The recommended operating tire pressure is
approximately 10 psi for the rear tires and 14 psi for the
front tires.

A fuse is installed in your tractor's wiring harness to
protect the tractor's electrical system from damage
caused by excessive amperage.
If the electrical system does not function, or your
tractor's engine will not crank, first check to be certain
that the fuse has not blown.
It can be found under the hood mounted behind the top
of the dash panel on the support bar.
