Checking Tires

1. Check tires for damage or noticeably low pressure.

2. Have any cuts or breaks repaired as soon as possible.

3. Protect tires from exposure to sunlight, petroleum products, and chemicals.

4. Try to avoid rocks and sharp objects: drive carefully.

5. At least every 50 hours of operation, check tires with an accurate gauge having 10 kPa (1 psi) graduations. If tires contain liquid ballast, use special air-water gauge and measure with valve stem on bottom.

IMPORTANT: Drive wheel tire pressure in normal field operation is 193 kPa (1.9 bar) (28 psi). If transporting on the road for more than a 1/2 hour with a 6 or 8 row head attached, drive tire pressure must be increased to 248 kPa (2.5 bar) (36 psi).

Wheel Type of Tire Tire Size kPa (bar) (psi)a
Drive Tractor (R-1) 23.1-26 14PR 193 (1.9) (28)
Guide Ribbed (Standard) 9.00 x 24 8PR 303 (3.0) (44)
Guide Cleated (Optional) 14.9 x 24 6PR 234 (2.3) 34
aInflation pressure is the same for tires with air or liquid.

 

6. Check and torque wheel hardware to specifications:
