CHECK PTO LENGTH - TURNING AND ON HILLS

The Pro-Flex 120 mower is designed for mowing of uneven,
contoured landscape. When negotiating turns, the input PTO shaft will
change in length. During mowing of steep contoured conditions,
when the tractor starts up a hill the PTO shaft will collapse and when
cresting the hill, it will extend. It is important to make sure that the
PTO shaft does not fully collapse, fully extend or contact the hose
shield or hose support rod during turns or when travelling over hills.
To ensure proper setup check the following conditions:
1) With the tractor in the lowest gear and travelling very slowly,
make a sharp turn to the right.
2) 2) Watch the PTO shielding to make sure the PTO shaft does
not totally collapse. There should be a minimum of 9 ½" of the
inner black PTO shielding exposed at maximum turn.
3) 3) Ensure PTO shielding does not come in contact with hose
support or hose support rod.
NOTE: This is not the worst condition. Making turns while the tractor
is angling up a hill will cause the PTO shaft to collapse even more.
Likewise, traveling straight up or down a hill will either extend of
collapse the PTO shaft. The operator should avoid making sharp
turns on uneven terrain.
If the PTO over extends, it will come apart and can cause injury
to the operator or
If the input PTO shaft collapses fully, it will force the shaft back
against the hanger bearing. This will cause damage and
premature failure of the bearing.

CHECK TIRE CONTACT DURING TURNS

The Pro-Flex 120 mower features a hose support which also serves
the function to limit the steering angle of the mower without damage
to components. In proper operation, the tractor tire should contact the
hose support first if the operator attempts to turn too sharp without
damage to the drive-line.
To check tire contact:
1) With the tractor in the lowest gear and travelling very slowly,
make a sharp turn.
2) As you turn, watch closely to make sure the tractor tires contact
the hose support. (not other parts of the mower)
3) If the tires do not contact the hose support, adjust tractor tire
width (if possible), so they contact the hose support. Contact us
for a modified guard.
NOTE: Using this setup, with the proper adjustment, the tire will
contact the hose support and will not allow the tractor to turn
any further. It will either, prevent the contacted tire from
turning, spin the opposite tire, or push the front of the tractor
around. This guard is not designed to work with lug style
tires.
