1954 Forestry Magazine Add for HD9X Shows how it workedl

The unique things about this tractor are:

The blade is physically attached to the nose of the machine;
The blade is raised and lowered by mid-tractor mounted hydraulic pistons that push against the truck frame. You go up and down like on a rocking horse.
The tractor was complete even in the battery boxes.
This tractor will be repainted to AC Colors and the house will be removed.
