tractor auxiliary hydraulic pump factory

Our PTO Auxiliary Hydraulic System is used for any type of agricultural equipment when an application or piece of equipment requires more hydraulic oil flow than the tractor/equipment can provide. Out most typical application is for Air Seeders (planters) when Ag Tractor Hydraulic systems don"t meet the flow, pressure or cooling requirements for proper operation of equipment. DFP"s PTO Auxiliary Hydraulic Systems are completely customizable to fit your specific application.

Hydraulic reservoir is typically 25 gallons, but capacity is flexible to meet any application requirements as these systems are built to order. Also included is a Spin-on Return Filter and an Oil Cooler (12VDC) with Temp. Switch mounted and plumbed to Hydraulic Reservoir (tank). (end user to supply power to 12VDC Fan on cooler) Other options for the hydraulic reservoir, but are not limited to: Relief Valve Block, Pressure and Tank Manifolds, Hydraulic Directional Control Valves and Flow Controls. DFP"s PTO Auxiliary Hydraulic Systems are completely customizable to fit your specific application.

This industrial built and designed 3-point auxiliary hydraulic unit allows you to operate attachments on tractors that don’t generate enough hydraulic horsepower on their own. This self-contained unit produces enough gallons per minute allowing you to operate these hydraulically-driven attachments, thus expanding the versatility and value of your tractor loader. The hydraulic pump offers superior performance over any of our competitors because it generates higher gallons per minute and line pressure. This allows for a wider range of attachments to be used.

High performance and dependability are the trademarks of all Kawak Auxiliary Hydraulic Systems. The Kawak Bell 47 auxiliary hydraulic pump is designed to provide an inexpensive, robust, and reliable replacement for pumps which have been previously installed. The Kawak auxiliary pump drive is also fully compatible with our Chemical Pumps and Boom Valve Assemblies.

These pumps are specially designed with drive shafts which have been engineered to shear when torque between 850-1000in/lbs is applied. This feature functions as an automatic system disconnect should the hydraulic system malfunction while the aircraft is operating. The adapter plate which attaches the pump to the engine pad also includes a drain port which allows for simple inspection of failing pump shaft seals to enable the operator to minimize revenue-generating aircraft downtime.

The use of hydraulic pumps in tractors has not been around as long as you might think. The first hydraulic system wasn’t developed until the 1930s in the United Kingdom, by Harry Ferguson. He invented what is known as the Ferguson three-point linkage system powered using the unique and still used Scotch Yoke piston pump.

His hitch system used hydraulics to raise and lower implements on the tractor, as well as the depth of an attached plough. His newly designed tractors did not take off too well initially. Once he partnered with Henry Ford in 1938, and soon after, his tractor hydraulic pump design was being copied and used by other manufacturers.1

Over the years, as hydraulics technologies have advanced, so, too, have the uses in tractors. Hydraulic systems were added to control front and rear attachments, driving motors, and various components on the attachments. In addition, steering and braking systems on tractors were adapted to work hydraulically.

When computer technologies came along, it helped advance hydraulic systems. Computer-controlled hydraulic pumps and systems in tractors can carry out functions and commands much faster than having to move a lever or push a button. Some functions can be pre-programmed and executed with precision control.

In addition, new transmission designs are incorporating the use of hydraulic pumps and motors to supply power to the front and rear axles for more effective control. This advance was developed in AGCO Fendt’s 1000 Vario series of tractors. Their creation was the first variable powered drivetrain invented for use in tractors.

Tractor hydraulic pumps and systems have come a long way since the 1930s. Today, you can use hydraulics with very sophisticated systems like operating air planters that plant seeds and spread fertilizer simultaneously.

Or you can hang an external pump, reservoir, and valve to have greater flow and more versatility. My MF-236 loader used a leg of the main frame for the reservoir, has its own valves and used a pump on the PTO. I later changed that to a pump running off the front of the engine. The front axle pivot is hollow and in line with the crankshaft. The pulley had a place to bolt a flange, which I made, though the parts may yet exist, and made a shaft to the pump sitting on a shelf under the radiator. I cut the bottom radiator shroud to clear the pump.
