Safety Interlock System Check

Service Interval: Every Fall & Spring
Check the function of the safety interlock system using
the test procedure found on page 12 of this manual. If
the tractor fails any of the tests, see your dealer.

Blade Brake Check

Service Interval: Every 100 Hours or Fall & Spring
Mower blades and mower drive belt should come to a
complete stop within five seconds after electric PTO
switch is turned off.
1. With tractor in neutral, PTO disengaged and operator
in seat, start the engine.
2. Look over the left-hand footrest at the mower drive
belt. Engage the PTO and wait several seconds.
Disengage the PTO and check the amount of time it
takes for the mower drive belt to stop.
3. If mower drive belt does not stop within five seconds,
re-adjust the clutch or see your dealer.
Check Tire Pressures
Service Interval: Every 25 Hours
Tire Pressure should be checked periodically, and
maintained at the levels shown in the chart. Note that
these pressures may differ slightly from the "Max
Inflation" stamped on the side-wall of the tires. The
pressures shown provide proper traction, improve cut
quality, and extend tire life.

PTO Clutch Adjustment Check

Service Interval: Every 250 Hrs
Check the PTO clutch adjustment after every 250 hours
of operation–or if the clutch starts slipping or will not
engage. Check and adjust the clutch using the
procedure outlined in the Adjustments section of this
manual.
