The tractors needed more traction to get around under load on the damp soils in the irrigated fields. They also didn"t have the hydraulic capacity to handle more than a bale or two at a time.

The Kalcevics looked around for a heftier loader tractor, but couldn"t find what they wanted. They already had an early 1960"s vintage Wagner articulated 4-WD tractor that was no longer big enough to get much use on their growing farm. And they had a couple of Versatile 145 articulated 4-WD"s, too.

"We"d bought the Wagner used from a dealer in 1968 and had used it a lot for light tillage and drilling grain, but by the early 1970"s, it was just too small for most tillage tools on our farm," Johnny says.

But the old Wagner was a far cry from a loader tractor. Its 453 Turbo 4-cylinder Detroit diesel, rated at about 140 hp, gave it plenty of power for what they wanted it to do. But there was no place to mount a forklift mast and the original hydraulic system was under-powered to handle it. Also, the standard transmission was going to be difficult to work with in hay loading, and the old cab was noisy and needed better climate control for those hot days in the hayfield.

To increase the hydraulic capacity of the tractor, they piggybacked a second hydraulic pump on the tractor. "With the second pump, we have a 20 gal. per minute flow to the fork and 24 gpm on the steering, so we can turn and use the fork at the same time," he says.

Finally, because they felt they needed more electrical capacity to reliably handle the electronic over hydraulic controls on the Freeman mast and the hydrostatic transmission, they replaced the old alternator with a 120-amp Delco alternator.

The Wagner project went so well they decided to convert one of the Versatile 145"s in the same way. With its 180 hp Cummins diesel V-8, the 145 had more power than the Wagner, but needed the same changes in the cab, hydraulics, alternator and drive system. It also lacked mountings for the forklift.

The biggest difference between the Wagner and Versatile conversions, he says, was that the hydraulic reservoir on the Versatile was inadequate. However, it had two 40-gal. fuel tanks. They solved the hydraulic fluid volume problem by converting one fuel tank into a hydraulic reservoir.

Small 4-WD"s Make Great Loaders For Big Bales TRACTORS Loaders 26-1-3 Joe Kalcevic and his sons Johnny, Jim, and Joe, Bennett, Colorado, produce high-quality hay on 1,000 irrigated acres just east of Denver. That"s a lot of hay, but it pales by comparison to their 80,000-plus acres of small grains and other crops. All the hay that is not used on the farm is sold directly out of the field. Because there are always plenty of other tasks demanding their attention, they needed a quick way to handle big bales. For years they used 2-WD industrial fork tractors with Freeman squeeze masts. "The fork masts were great, but we had problems with the two-wheel drive tractors," Johnny says.The tractors needed more traction to get around under load on the damp soils in the irrigated fields.

Also, the standard transmission was going to be difficult to work with in hay loading, and the old cab was noisy and needed better climate control for those hot days in the hayfield.They decided to mount the forklift mast on back and turn the cab 180 degrees so the operator faced the rear. "We rebuilt the cab so it was better insulated and sound-proofed, and then attached it to a separate base and mounted that on rubber," he says.While they were working on the cab, they pulled out the clutch and transmission and replaced them with a hydrostatic drive system. "We had to mount an adapter plate on the flywheel housing of the engine. We coupled a hydrostat motor on the upper drive line from the engine to the drivline into the drop box that powers all 4 wheels," he says.To increase the hydraulic capacity of the tractor, they piggybacked a second hydraulic pump on the tractor. "With the second pump, we have a 20 gal. per minute flow to the fork and 24 gpm on the steering, so we can turn and use the fork at the same time," he says.They added an oil cooling system and replaced the standard engine fan with one on which the blades had more pitch to increase airflow. They also added a new condenser to air condition the cab.Finally, because they felt they needed more electrical capacity to reliably handle the electronic over hydraulic controls on the Freeman mast and the hydrostatic transmission, they replaced the old alternator with a 120-amp Delco alternator.Johnny says they can now handle four 4 by 4 by 8-ft. bales by putting two together and then stacking two more on top of them before picking up the four to haul off the field to a waiting semi-trailer.The Wagner project went so well they decided to convert one of the Versatile 145"s in the same way.

The 972M hydraulic system has significant design changes and customer value improvements. The main hydraulic valve is now a mono-block with an integrated ride control section. The mono-block design reduces weight, has forty percent fewer leak points and is common across all M Series models. Auxiliary third and fourth hydraulic functions can be easily added at the factory or in the field with the addition of a second remote valve.

The new ride control system now has two accumulators enabling it to be more effective over a greater payload range, increasing productivity and operator efficiency due to a better ride. The next generation implement pump continuously and automatically balance hydraulic loads with the machine performance desired by the operator. Engine response is improved as is performance at higher altitudes.

The 972M power train has been improved with the addition of a lock-up clutch torque converter standard. These new torque converters have been matched with the engine power and hydraulics to improve performance and fuel efficiency. These rugged planetary transmissions also have a new split-flow oil system which use new multi-viscosity oil to improve fuel economy.

The deep system integration of the new engine and emissions system, power train, hydraulic system and cooling system result in 10% lower fuel consumption on average compared to the 972K. The new 972M is second only to the 972M XE which is the class leader in fuel efficiency.

Your operators will enjoy and quickly adopt the industry leading seat mounted EH joystick steering system, which provide precision control and dramatically decrease operator arm fatigue. For operators who prefer a steering wheel, an electro-hydraulic steering wheel is available as an option.

Fusion is the patented wheel loader coupler system from Caterpillar. The Fusion Coupler System provides performance virtually identical to pin on - with all the flexibility of a quick coupler system. The Fusion Coupler sits back, close in to the loader arms - minimizing offset and increasing the machine’s performance.

Fusion is designed to integrate the work tool and the machine by pulling the coupler and tool closer in to the loader. As a result, the center of gravity is moved inward, towards the machine. This translates to increased lifting ability when compared to machines equipped with other coupler systems.

PAYLOAD technologies enable accurate weight measurement of material being loaded or hauled. Payload information is shared with loader operators in real-time to improve productivity, reduce overloading and record both weights and number of loads per shift.

Monitoring product health is key to optimizing the life of an investment into a Cat Wheel Loader.Cat Product Link - Cat Product Link allows remote monitoring of equipment to improve overall fleet management effectiveness. Product Link is deeply integrated into machine systems. Events and diagnostic codes, as well as hours, fuel, idle time and other detailed information are transmitted to a secure web based application, VisionLink. VisionLink includes powerful tools to convey information to users and dealers, including mapping, working and idle time, fuel level and more.

Machine configuration, operator technique, and job site layout can impact fuel consumption by as much as 30 percent. Data from customer machines show Cat wheel loaders are the most fuel efficient machines in the industry. Several features contribute to this excellent fuel efficiency:New M Series U.S. EPA Tier 4 Final/EU Stage IV Engine, Hydraulics, Transmission and Ride Control - Deep system integration results in reduced emissions, more productivity, lower fuel consumption, without interrupting machine performance - making it seamless to you and your operators.

Loading Bucket - Load in first gear and keep engine rpm low. Raise and tilt bucket smoother, with Caterpillar’s multi-function capability, and do not use a “pumping” motion. Avoid lift lever detent and use of transmission neutralizer. Use programmable kick-outs and automatic cylinder snubbing during repeated cycles.

The Cat sloped “one-piece” tilting hood provides industry leading access to the engine. Its design has further been improved on all M Series wheel loaders to provide the best-in-class service access to engine, oil levels and coolant sight gauge.

The cooling system is readily accessible for clean out and maintenance. With nine cooling fins per 25.4 mm (1.0 in) and a perforated grill, most airborne debris entering the system passes through the cooler cores. The hydraulic and A/C cooler cores swing out providing easy access to both sides for cleaning. An access panel on the left side of the cooling package swings down to provide access to the back side of the engine coolant and Air-to-Air After Cooler (ATAAC). An optional variable pitch fan can automatically purge the cooler cores by periodically reversing the airflow when needed.

The electrical and hydraulic service centers provide grouped ground level access to numerous features, enhancing safety and convenience for your operators and service technicians, while reducing service time. The electrical service center, located beneath the left platform, contains the maintenance free batteries, a fuse relay panel, main disconnect switch, ground level engine shutdown switch, hood tilt switch, and the jump start receptacle. Hydraulic system components on the 972M and 972M XE are protected by full flow and kidney-loop filtration. A filter in the hydraulic tank return line filters all of the oil returning to the tank. There is also a case drain screen for additional protection and finally, a separate kidney-loop filter with a finer micron rating continuously filters smaller particles out of the system. This multilevel design ensures the hydraulic oil is clean and thoroughly protects the rest of the hydraulic system from contamination. A new thermal bypass valve has been added to improve hydraulic system warm-up. The hydraulic service centers are now virtually identical for the M Series product line. This new consistent layout makes it easier for service technicians who work on a variety of M Series models.

Linde Hydraulics has developed a system to receive considerable reduction of fuel consumption and noise emissions as well as lower initial and operating costs. This innovative system called Shift in Motion for hydrostatic drive consists of a variable displacement pump, a variable displacement motor, a shift actuator and an electronic control unit.

It enables shifting procedures in a moving machine, equipped with a manual transmission that is intended to be shifted at standstill by electro-hydraulically synchronising the drivetrain. This system is particularly suitable for vehicles that require both, high tractive effort and a high top speed above 25 km/h - for example for small and compact wheel loaders.

The shifting procedure is load-free thanks to electro-hydraulically synchronised gears and the ability to adjust the drive component"s speed and torque. Thus there is no need for multi-disc clutches and mechanical synchronisation using synchronizer rings and moreover there"s less pinion engagement. This makes the shifting procedures wear-free and also increases the transmission"s efficiency.

The diesel engine isn’t really the heart of a skid steer. When it comes to a heart (the machine’s pumps), a skid steer or track loader actually has three or four hydraulic hearts. These pumps power fluids — compressed oil — to move, spin, lift the boom, curl the bucket and run a zillion different attachments. This set of hydraulic pumps (gear, hydrostatic, tandem, back to back, variable displacement) come in many configurations, brands and power ranges. Over the last decade in particular, the science and technology behind these systems has made them smaller, more efficient and more sophisticated.

“Probably one of the biggest innovations in the last five to 10 years has been the advent of electronically controlled hydraulic systems. We call them EH systems,” explains Nathan Wood, hydraulics system engineer for John Deere Construction and Forestry. “You’re controlling the hydraulic system precisely with electronic signals. It leads to a lot more controllability and a lot more ability to do different types of automated controls and functionalities.”

“Originally the first skid steers were hydrostatic controlled by mechanical linkages,” says Kevin Scotese, product manager of sales support, compact equipment, at Volvo Construction Equipment. “The next step in the evolution was the implementation of pilot controls, and the last step has been in the improvements of electro hydraulic controls, which provide the possibility to customize the feel, speed and responsiveness. Another technology to maximize the power and reduce parasitic losses is the implementation of state-of-the-art closed center load-sensing systems in combination with the variable axial displacement piston pumps.”

Pretty high-tech stuff, eh? Today, fluid power is being used to control everything from the tracks to the attachments to the cooling fan to automated features such as creep mode, return to dig and settable attachment speeds — all built right into the joystick. But as you might expect, skid steer and track loader hydraulic systems have gotten quite complex, and just like any oil system in a machine, it will definitely require routine maintenance, testing and proper seasonal oil.

Well, that all depends on the size and configuration of each skid steer or track loader. Every brand is somewhat similar, but each unit is engineered uniquely. Let’s break the system down into two parts: 1) the hydraulics powering the boom, bucket and auxiliary circuit and 2) the hydrostatics powering the wheels or tracks. The hydraulic system powering the boom, attachment, automation features and even cooling usually uses up to three pumps — a main hydraulic pump, a charge pump, which provides control pressure, cooling and fan power, and if you get the high-flow option, a third high-flow pump. Without that option, there are two.

“For the pumps powering the arm, bucket and auxiliary hydraulics, smaller machines run a gear pump, but on the larger models this is a load-sensing axial variable displacement pump limiting the parasitic losses and providing better power to the loader functions and auxiliary,” says Scotese. “For the auxiliary, high-flow option on the smaller models, an additional gear pump is utilized in tandem to provide the required flow. On larger models, a higher-capacity load sensing axial variable displacement pump is providing the higher flow. Charge pressure and flow for the transmission and hydraulic fan motor is usually provided by a smaller PTO-mounted gear pump.”

When it comes to powering the tracks or wheels, there is a bigger, double-pronged hydrostatic pump that powers the machine’s mobility. There is a hydrostatic pump that provides flow and pressure to one motor on the right-hand side and one motor on the left-hand side. On a skid steer or track loader, it’s usually one tandem pump or back to back, providing dual power to two motors for each set of wheels or tracks.

Manufacturers use lots of different brands of pumps — Danfoss,Turolla, Rexroth, Concentric, Eaton and Parker Hannifin. These pumps combined with the overall hydraulic systems come with three main specifications — system pressure (psi), gallons per minute flow to the attachment (gpm) and overall hydraulic horsepower (which tops off about 100 hp). Each manufacturer will engineer and market those specs differently.

“Starting with the hydrostatic system, the transmission and drives system, pressures are pretty high, upward of 6,000 psi,” explains Woods. “These are heavy-duty components to get the speed and torque you want. When it comes to the hydraulic system, bucket, boom and aux, typically you’re running between 3,000 and 5,000 psi. We run right around the 3,500-psi range. We find that that allows us to use reasonably sized cylinders and boom geometry to get the breakouts we need, while still maintain the speed we require.”

Hydraulic flow to the auxiliary circuit and the attachment will be determined in gpm and as standard- and high-flow configurations. Bobcat’s tiny S70 skid steer uses 9.8 gpm for its standard flow system. The optional high-flow on the Takeuchi TLV12V2 (the biggest track loader on the market) is 40.4 gpm. The price difference between standard and high flow usually falls right around the $3,500 range (5 to 7 percent more), and the high-flow option is usually more common on the largest skid steers and track loaders.

“ASV builds the widest range of track loaders in the industry from the RT-30 with a flow of 10 gpm up to the RT-120 with a max flow of 45 gpm,” says Bill Wake, ASV director of product development. “The RT-120 also features variable flows and operator adjustable settings ranging from 0 to 45 gpm depending on the attachments needs.”

Let’s start off with this ubiquitous warning: It’s very important to review your owner/operator’s manual before attempting to perform any maintenance to the hydraulic system, taking special care to review the safety procedures listed in the manual. With the variety of options available today such as high flow, bucket self-leveling, ride control and hydraulic quick-attach brackets, there may be up to five or six control valves as well as pumps. All of these components are designed with very tight tolerances, which may fall below 0.001 in. Because of this, keeping the hydraulic system clean is critical to the life of these components.

“Keeping the system clean and cool is the No. 1 objective,” explains Wake. “ASV has the largest cooling packages and hydraulic tank capacities in their respective classes. That combined with double and triple filtering assures the oil is kept both clean and cool. Owners can help by following the maintenance guidelines in the machine’s owner’s manual, as well as making sure to clean around the hydraulic cap before removing. Be sure any hose fitting is cleaned before removal, and wipe off quick-coupler ends before hooking attachments to the machine.”

Contamination can enter the system in a variety of ways. Before removing the hydraulic oil reservoir cap, clean the area around it to prevent dirt from entering the tank. If using a bucket, make sure that there is no loose dirt on the lip. While all machines will have at least one hydraulic filter to remove debris from the system, this filter might be in the return side of the hydraulic system. There is a screen inside the tank to prevent large material from getting into the pumps, but it won’t catch small particles. Make sure you look for features from brands that make using and cleaning the hydraulic system easier.

“A very important feature which is standard on Volvo skid steers is the case drain on the auxiliary block and the pressure relieving by simply pushing in the quick-connect couplers on the manifold which simply vents pressurized oil in the main lines to the tank. This is a very well-liked feature to ease the hookup of hydraulic lines,” says Scotese.

In order to further prevent contamination, make sure to follow the OEM’s service interval for hydraulic filter replacement. This may fall anywhere between 500 to 1,000 hours depending on manufacturer and operating conditions. A plugged up hydraulic filter may cause a variety of issues such as loss of speed or power, overheating of the hydraulic oil and damage of components. What type of hydraulic oil should be used in your loader?

Just as important as the type of hydraulic oil used is the amount in the tank. The operator’s manual will show where the level should be within the sight glass and where the boom and bucket should be located while checking the hydraulic oil level. Most machines should be checked on a level surface while having the boom all the way down and the bucket flat on the ground. Hydraulic oil should be checked daily, if not before every time the machine is operated. If the level is low, look around carefully for leaks. Given the dusty and dirty conditions that skid steer loaders and compact track loaders operate in, it is not uncommon for debris to damage the hydraulics and thus affect things like “feeding speed.”

“Brushcutting and cold planing are a couple examples of demanding applications on a hydraulic system,” says Wake. “Both can use 100 percent power at nearly 100 percent of the time. In demanding applications like this, the key to maximum production is feeding speed. Feeding the attachment at a rate to use 100 percent of the power — but not exceeding it to the point the engine bogs, the attachment slows greatly or the attachment stops — will give the most production with the least demand on the machine and operator. A feed pace with the engine pulling a few hundred rpm off peak, tends to be the sweet spot.”

The accumulation of debris from an application like brush cutting can harm the hydraulic cooler. The oil cooler might use engine coolant or outside air to cool the oil. It is vital that the oil remain within the acceptable operating temperature range. Make sure the oil cooler is free of debris and the cooling fins are fairly straight. “John Deere has an electronically controlled hydraulic fan that can vary the speed based on the required cooling,” says Wood. “It’ll also automatically reverse at a set interval to expel the debris built up on the coolers to help limit the number of times you actually have to physically clean out the cooling package.”

Another common way for contamination to enter the hydraulic system is by using hydraulically powered attachments. Before connecting any of the auxiliary hoses, be sure to wipe off the connectors to get rid of any water, dust or other debris. If an attachment was used on a loader that had a hydraulic failure and spread contamination into the attachment, that contamination may enter the next machine it’s connected to.

“That’s probably one of the more concerning things,” says Gregg Zupancic, product marketing manager of skid steers and compact track loaders with John Deere Construction and Forestry. “When you rent attachments, the question is: Who rented that machine last, and what types of materials are in their hydraulic systems and sitting in that attachment unused for a long period of time? That’s why you do things like hydraulic fluid sampling.”

The Cool Flow hydraulic oil cooler from Loftness Specialized Equipment greatly reduces the risk of overheating in skid steers and hydraulically powered attachments when operating in demanding applications and hot work environments. The automatic thermostat-controlled fan provides adequate cooling to the system whenever needed to boost machine efficiency, even when an attachment is not being used. Unlike most other hydraulic coolers that are mounted near the attachment, the Cool Flow attaches to the roof of a skid steer cab where it is less susceptible to vibration, back pressure, debris and potential impact damage. It is specially engineered to allow full hydraulic flow to the attachment in either direction without risk of damage to the cooler. The Cool Flow has up to 40-gpm flow capacity and is compatible with all brands of skid steers.Concentric, Danfoss, Eaton, home, John Deere, March 2016 Print Issue, Parker Hannifin, Rexroth, Turolla, Volvo Construction Equipment

The piston pump has been designed, developed and enhanced for professional use. It allows a wide range of materials to be processed, from paints to coatings to plasters and adhesives, which is of course ideal for painting businesses. There, the acquisition costs are quickly written off through frequent use. By spraying the coating material, you save an enormous amount of time, which you can invest in other projects. The amount of material consumed is also less compared to other application methods.

WAGNER devices with a piston pump are available either as electric drive or petrol (especially the larger machines) and can even be converted from one drive to the other, so you are completely flexible and independent of the power supply on construction sites.

The smaller devices, however, are not only suitable for craftsmen, but also for active DIY-ers who tackle their own projects around the houseand where the paint sprayer will often be in use. For example, if you want to spray a property exterior yourself, or treat a patio or garden shed, you may well consider whether a paint sprayer with an electric piston pump is the right thing for you.
