Remove & Refitment of Safety Neutral Switch
In order to prevent starting of the tractor in gear or
when PTO is engaged, unknowingly, which can lead
to accident, a safety feature is provided. The starting
system of the tractor is linked with the switch on
forward / reverse shuttle shifting and PTO system. Hence
tractor can be started only if forward / reverse shuttle
shifting and PTO are in neutral.
Do not start the tractor by shorting
at starter motor as this will bypass neutral system and
can lead to accident
Removal of Neutral Safety Switch
1. To remove the switch, first remove the battery
cable from its negative terminal & then remove
battery cable from positive terminal.
2. Disconnect wiring harness from neutral switch.
3. Loosen the nut holding the switch to the bracket
and remove the switch.
NOTE: After removal of the switch preserve the shims.
Refitment of Neutral Safety Switch
1. Position forward/ reverse lever in neutral position.
2. Refit the switch by using removed shims. For new
switch add / remove shims, so that the tractor
starts in neutral position only.
3. After ensuring startability in neutral position,
tighten all hardwares to complete the assembly.
NOTE: Incase forward / reverse pivot is removed
during any repairs; first reassemble the
forward / reverse pivot on transmission shaft.
Reconnect the forward / reverse cable with pin,
cotter pin and washer. Place the forward /
reverse in neutral position. Refit the switch
by adding / removing shims, so that the tractor
starts in neutral position only. After ensuring
startability in neutral position, tighten all
hardwares to complete the assembly.
