depress brake pedal all the way down and engage
parking brake.
•

in "transmission disengaged" 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 manu-
ally push the tractor forward. If the rear wheels rotate,
then the brake needs to be serviced. Contact a qualified
service center.
