 "GROUNDSAW"

 TRENCHER

MODEL H-900 KIT FOR
ALLIS-CHALMERS B-10 TRACTORS

Patents Pending

CARBIDE TIPPED CHAIN

The “Groundsaw” trencher is designed around a new high speed trenching chain. The bucket design makes it possible to dig in solid frozen earth. Carbide teeth on all trenching chains are standard equipment with the “Groundsaw.” The Model H-900 is a completely hydraulic unit including pump and hydraulic motor on the trenching chain drive. Hydraulic boom depth control, hydraulic motor traction drive with automatic sensing valve to control forward speeds.

This unit comes completely assembled ready to attach to the tractor with one pin and one bolt, one sheave to be put on the tractor power takeoff and slip on two belts, fill the oil reservoir and it is ready to go. Standard depth is 30 inches, with a 36 inch extension available.

Trench width is from 2-¼”, 3", 4” and on special order, 6”. Hydrostatic drives make it ideal to control shock loads such as are encountered in trenching. Oil filter is easily serviced.

These features practically eliminate all breakage and down time which is costly. The ease of handling this all hydraulic unit eliminates back breaking hand labor and can be used with the regular Allis-Chalmers dozer blade for back filling and packing the trench. With the hydraulic control in the traction drive, there is no  stopping for clutching and shifting gears as the control can be used for forward and reverse, making it an ideal operation for dozing.
