1.Gear units - Move transmission shift lever (A) to N (NEUTRAL) position.

Automatic units - If equipped with shift lever, move shift lever to N (NEUTRAL) position. If equipped with foot pedal controls, do not depress either pedal.

2.Lock the park brake (B).

3.Pull PTO lever (C) all the way back to the rearward (OFF) position.

4.To start the engine:

•S1642 and S1742 - Place the throttle lever (D) in the CHOKE (￿) position. As the engine begins to run smoothly, lower the throttle lever in small steps, allowing

the engine to accept changes in speed and load, until the throttle lever is in the FAST (￿) position.

•S2046 - Place the throttle lever (D) the FAST (￿) position and pull out choke knob (E). As the engine begins to run smoothly, push the choke knob in until fully seated.

5.Turn ignition key (F) to start position to crank the engine. Crank engine until it starts, but no longer than 5 seconds.

6.If engine starts, release key to run position. If engine does not start, release key to run position and wait 10 seconds before cranking the engine again.

7.Let engine run for a couple of minutes to warm-up before operating tractor.

Using Throttle Control

Always operate the engine at FULL (￿)THROTTLE.

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:

A

M96455

•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.
