Recommended Engine Speeds and Operating Procedures

Tachometer (A) shows engine rpm, read in hundreds.

Warm Up Engine

Do not place tractor under full load until it is properly warmed up.

2. Run engine at about 1900 rpm and under light load until engine reaches normal operation condition.

Avoid Idling Engine

Allowing engine to idle at low rpm uses fuel inefficiently, and can cause a build-up of carbon in the engine.

If tractor must be left with the engine running more than 3 or 4 minutes, minimum engine speed should be 1200 rpm.

Observe Engine Work and Idle Speeds Consistency

Slow idle speed should be 900 ± 50 rpm. At light or no load, full throttle speed will increase to 2625 ± 25 rpm.

Normal working speed is 1600-2400 rpm rated speed. Within these limits engine can be put under full load.

For correct PTO speed.

Restart Stalled Engine

Should the engine stall when operating under load, depress clutch and restart it immediately to prevent abnormal heat build-up and continue with normal operation, or operate at slow idle for 1 or 2 minutes before stopping.
