CHECK PTO DRIVELINE DURING MANEUVERS
The TD92 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 input shaft will collapse and when cresting the hill, it
will extend. It is important to make sure that the input shaft does not
fully collapse, over-extend or contact the hose support 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 driveline shielding to make sure the input shaft
does not totally collapse. There should be a minimum of 1/2
” of
the inner black shielding exposed at maximum turn.
3) 3) Ensure input shaft 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 damage to the mower or tractor.
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 TD92 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: With 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 will not work
with lug style tires.
