overshot loader factory

The cycle time was actually decreased. After taking on a load in the bucket the tractor simply moved straight back to unload. The distance between loading and unloading the bucket was usually that which was required to allow the loader to make its complete lift as the tractor moved backward to the dump point. When the operator got more proficent the machine would arrive at the dump point at, or just a second or two before the bucket unloaded. The loader on the HD5 raised fairly quickly. As such, from the time the bucket was full and operator started the unload cycle the tractor only needed to travel in reverse about 40 ft. After dumping it took that 40ft. to travel forward again and have the bucket back on the groung ready to take on the next load.

A small town near here used that same HD5 to load snow off the street after windrowing it with a grader. A truck would back into position and the loader would simply move back and forth between the windrow and the truck to load the snow. The crawler, as most crawler loaders do, had street pads on it so no damage was done to the pavement. Every once in a while the loader operator wouldn"t notice that the truck had backed up a bit and there would be this load crash when the loader smacked into the truck. The tail gate on the truck took quite a beating by the time spring rolled around. I made a few impressions on the tailgate myself.

At the gravel crusher, a dozer pushed the material into position and the loader just performed its forth and back routine to feed the cruaher. Worked great.

Marv’s Jayhawk is an overshot hay stacker, a piece of horse-drawn farm equipment patented in 1915. Manufactured by the F. Wyatt Mfg. Co. (which evolved into what is today the Hesston Corp.) in Salina, Kan., the long and leggy Jayhawk is a clutch-driven creature that stumps almost every onlooker. Measuring 12 feet wide, 30 feet long and 12 feet high with an 80-inch rear axle, the Jayhawk has a “head” (or “sweep”) originally used to lift hay into bins or cribs. “The head trips like a trip bucket on a tractor,” Marv says. “When it gets up so high, there’s a lever that dumps the load.” The sweep could hold approximately 600 pounds of loose hay as it swept overhead.

Although the Jayhawk is a deceptively simple conglomeration of steel and cables, chains and wood, Marv invested nearly 40 hours in its restoration. He had to find new rear wheels because the original ones had been removed to allow a tractor to push the stacker. “When they converted it for use with a tractor, it was just a convenience,” he says. “I don’t know if they hooked it to a loader-type tractor or not. A mechanical lift on the front of a tractor is like a fifth wheel on a truck. That’s why they had to get rid of the rear wheels.”

Hay loaders and balers served farmers in a slightly different capacity than the Jayhawk. “The hay loader was the other thing that would’ve come after the hay stacker,” Marv says. “I’ve got a dump rake and the old side-delivery rake here, and the horse mower. I have a chain of command of haying pieces.” Several other restoration projects await, but for now, Marv is simply pleased to be able to display his haying equipment, including the flightless Jayhawk.
