10.11. The socket head cap screws that secure the
neutral return assemblies to the hydros act as a
travel stop at the hydro end of the linkage. The
lap bar pivot brackets should contact the stop
screws before the socket head cap screw con-
tacts the end of the slot on the neutral bracket.
See Figure 10.11.

10.13. After final adjustment, test the operation of the
reverse safety switches. They should turn the
PTO clutch off whenever both lap bars are in the
reverse position.
NOTE: With one lap bar in the reverse position,
and the PTO turned on, the PTO clutch should
turn off as soon as the second lap bar crosses
the threshold from neutral into reverse. Repeat
test for each side.
NOTE: When at least one lap bar is in the neu-
tral or forward position, the PTO clutch will oper-
ate. There is not a relay to re-set by cycling the
PTO switch off and on again, as is the case with
MTD front engine residential equipment.
10.14. If the reverse safety switch adjustment is not
correct, loosen the reverse safety switch bracket
using a 3/8" wrench. Pivot the bracket and
switch to a position that results in correct opera-
tion, then tighten the bracket. See Figure 10.14.

NOTE: It is not necessary to remove either con-
trol console to reach the reverse safety switches,
but it may be necessary to temporarily discon-
nect the blue wires in order to reach the mount-
ing screws for the brackets.
