Speeds shown represent following tire sizes at rated
rpm (2100):
18.4 x 38 R1
23.1 X 34 R1
24.5
x 32 R1
24.5
x 32 LS2
20.8
x 38 R1
30.5L x 32 R1
To determine speed for other tire sizes use the
following chart multipliers:
Average Static Tire Size Factor
Loaded R.R.
30.7. 20.8 x 34 R1
33.5 20.8 x 38 R2
33.7 18.4 x 42 R1
34.6 20.8 x 42 R1
33.0 30.5L x 32 R2
32.5
30.5L x 32 LS2
Example of Use:
If chart speed was 14.6 MPH and tractor
was equipped with 20.8 x 34 R1 tires,
Then:
MPH = (Chart) x (Factor)
.96
1.05

Engine Speeds·
If MPH is wanted for engine speeds other than rated,
MPH= MPH (Chart) x Engine RPM
Rated RPM
Example:
If chart speed was 14.6 MPH and tractor has engine
with rated speed of 2100 RPM and MPH wanted at
1800 RPM,
Then:
MPH= 14.6 x 1800 = 12.5 MPH
