A-Tachometer

B-2400 rpm Mark (540 PTO rpm)

C-2200 rpm Mark (540 PTO rpm)

  

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

Warming Up Engine

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

1. Idle engine at 1200-1500 rpm for several minutes.

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 three or four minutes, minimum engine speed should be 1200 rpm.

Observe Engine Work and Idle Speeds

For 5045E, 5055E, 5065E and 5075E Tractors

Slow idle speed should be 825 ±25 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, run engine at 2400 rpm for standard 540 rpm operation.

Observe Engine Work and Idle Speeds

For 5045D and 5055D Tractors

Slow idle speed should be 825 ±25 rpm. At light or no load, full throttle speed will increase to 2525 ±25 rpm.

Normal working speed is 1600-2300 rpm rated speed. Within these limits engine can be put under full load.

For correct PTO speed, run engine at 2200 rpm for standard 540 rpm operation.

Restarting 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 one or two minutes before stopping.
