MOUNT REAR BLADE TO TRACTOR
IMPORTANT
The rear blade should be mounted on tractors
with a maximum power rating of 65 hp (48 kW). For
4WD tractors, the maximum power rating is 60 hp
(45 kW).
The rear blade is a 3-point Category 1 implement. It will
attach to ASAE standard Category 1 quick-attaching
coupler.
Place the tractor rockshift control in "position control"
(non-floating) for attaching and detaching the rear
mounted blade. "Draft control" or "position control" can
be used while operating.
Back the tractor until the ends of the lift arms can be
attached to the lift points on the implement. Secure the
lift arms to the mast.
Attach the center link to the top of the mast and adjust
so that the rear blade will be level in the operating
