Using Throttle Control

Always operate the engine at FULL (
Operating the engine at less that full throttle reduces the
battery charging rate and reduces fan cooling efficiency of
the engine.
Full throttle offers the best bagging and mower
performance.

Cold Weather Starting Tips

Always use fresh winter grade fuel.
Do not crank engine for more than 30 seconds in any single
attempt.
During first minute of operation engine may be operated in
partial choke to allow smoother running. As engine warms
slowly reduce engine speed to the full throttle detent
position.

On Automatic Transmission

Allow engine to run for a few minutes before using tractor to
allow automatic transmission oil to warm. Sluggish
transmission response in cold weather indicates that oil has
not warmed to allow optimum performance.

Warming and Idling Engine

WARMING ENGINE:
• Run Engine at half speed for 2–3 minutes.
IDLING ENGINE:
• Engine is air-cooled and needs a large volume of air to
keep cool. Keep air intake screen (A) on top of engine
clean.
• Avoid unnecessary engine idling.
