Estimated Drive Unit Speed Tables
Use these tables to estimate the Intermediate Drive Unit and End Drive Unit speed based on the drive unit
motor output RPM, tire size, and machine voltage. Refer to Figure 81-1.

Drive Unit Speed(ft/min) = (Tire rolling Circumference x Motor Speed(rpm))
(Gearbox Reduction(52) x 12)
** These speeds are estimates only. Actual speeds will vary according to inflation pressure and field conditions.
Machine speed should be measured after installation to determine the actual performance.
*** Includes turf tires of same nominal size.
