Mower "ON" / "OFF" Switch or Wiring Malfunction?
CAUTION, MAKE SURE TRACTOR IS IN NUETRAL WITH PARKING BRAKE
SET! MAKE SURE ENGINE IS DISABLED TO SO THAT IT WILL NOT
SUDDENLY START SHOULD IT START CRANKING, ALSO MAKE SURE
EVERYONE AROUND YOU KNOWS THAT THE TRACTOR ENGINE MAY
SUDDENLY START CRANKING! THIS BECAUSE WHEN DEALING WITH A
SHORT OR LOOSE CONNECTION YOU MAY MOVE IT AND MAKE IT START
TO OPERATE!
Check for Voltage at Starter Solenoid when Starter Switch is engaged. If
Voltage is not present make Sure Mower Switch is "Off" and recheck for Voltage
at Starter Solenoid. If still no Voltage check through circuit till voltage is found
(checking must be done with Starter Switch engaged). The faulty component
is most likely immediately down stream of the point of voltage. Repair or
Replace as needed and retest system. DO NOT BYPASS MOWER SWITCH
SAFETY FEATURE!
Most of the problems that will cause the Tractor Battery to fail drain power will
be found in the Tractor, However there is a cause that involves the Mower. Only
the problem that could be caused by the Mower is covered here, and only
mower models that have electrical systems that are tied in with Tractor
Electrical system could affect Tractor Battery Circuit.
"ON" / "OFF" Switch or Joystick Wired Incorrectly?
Power Wire from Tractor to Mower control system must be wired through the
Tractor Ignition (Key) Switch to where it only has current when Tractor (Key)
Ignition Switch is "ON". If the Mower Power Source is connected where it has
Power (Constant Power) when Tractor Ignition (Key) Switch is "OFF" it will put
a constant Drain on Battery. This is the only one problem that should be able
to affect Tractor Battery from Mower Electrical System. Check where Wiring is
connected, Correct as required, See Operators, Parts or Repair Manuals for
Wiring Schematics.
