Adjusting Set Speeds to Match Varying Load Conditions

Set speeds are obtained from measuring tractor axle speed combined with tire size details. Select a set speed that is approximately 3.2 km/h (2 mph) higher than the desired working speed in order to obtain maximum productivity in applications where a precise forward speed is not critical, such as plowing. The tractor will reach the higher set speed value during a no load or light load condition.

The ground speed (A) indicated on the display will always be lower than the set speed (B) if there is measurable wheel slip.
