TO CHECK BRAKE

stop at highest speed in highest gear on a
level, dry concrete or paved surface, then
brake must be serviced.

paved surface, depress brake pedal all
the way down and engage parking brake.
2. Disengage transmission by placing
freewheel control in "transmission disen-
gaged" position. Pull freewheel control
out and into the slot and release so it is
held in the disengaged position.
The rear wheels must lock and skid when
you try to manually push the tractor forward.
If the rear wheels rotate, then the brake
needs to be serviced. Contact a Sears or
other qualified service center.
