Walker SB6670, DB6680, DB6660, RB6650, IH6620 Attach Tractor PTO to Debris Blower Input Shaft

Assembly Instructions

14.For GHS (Grass Handling System) equipped Walker tractors, install a blower intake cover in the blower intake tube. The cover “unloads” the blower and seals the intake to effectively elimi- nate power loss and noise when the blower is not being used. Refer to GHS Blower Intake Cover illustration for ROTARY BROOM in this section.

15.For stability of the tractor when transporting with the snowblower in raised position, approximate- ly 80 lb (36 kg) of counterweight should be in- stalled on the tail of the tractor. Optional tail weights for the various tractor models are avail- able from your Walker dealer or a sandbag or similar weight may be used.
