CHECK PTO LENGTH - TURNING AND ON HILLS
The TDR-X 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 (shorten) 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 frame 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
– do not let the CV joint exceed 80 degrees
– see Figure 7 page 24.
2) Watch the PTO shielding to make sure the PTO shaft does not
totally collapse. There should be a minimum of 5
½” of the inner
black PTO shielding exposed at maximum turn.
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 or 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.
