TO CHECK BRAKE

stop at highest speed in highest gear on a
level, dry concrete or paved surface, then
brake must be serviced.
You may also check brake by:
1. Park tractor on a level, dry concrete or
paved surface, depress brake pedal
all the way down and engage parking
brake.
2. Disengage transmission by placing
freewheel control in "transmission dis-
engaged" position. Pull freewheel con-
trol out and into the slot and release so
