Abstract: Apparatus for cultivating soil and sowing and bedding seed and/or fertilizer on steep slopes. A tractor comprises a chassis which is supported for movement along a path over terrain by endless tracks. The tracks have lateral widths which are optimum relatively to the overall width of the tractor to enable operation of the apparatus over steep grades. A scraper blade is carried on the front end of the chassis, and a seed/fertilizer broadcaster is mounted on the scraper blade. A harrow for working and bedding soil is mounted on the rear end of the chassis. The tractor can be configured in different modes with the scraper and/or the harrow in either up or down positions while the broadcaster is either turned on or off.

Abstract: A crawler tractor is disclosed with a counterweight assembly which affords optimum weight distribution and traction for operation on steep slopes and grades. The assembly includes a counterweight body having a shank which is carried by a housing mounted by a support arm weldment on the rear end of the tractor. The shank is releasably engaged with the housing. Hydraulic actuators are provided to move the counterweight to a lowered position for backing the tractor uphill, and for raising the counterweight for dozing in a downhill direction. One embodiment provides for selective fore and aft positioning of the counterweight relative to the tractor in accordance with operating conditions.
