Check the Oil Sight-Glass (when the Tire Combination has been Changed)

IMPORTANT: If a different tire combination is selected, or new rear tires are selected with an SRI (speed/radius index) higher than the previous ones, the tractor's electronics must be recalibrated by your John Deere dealer.

Refer to "Specifications" section for the SRI (speed/radius index) of the tires supplied with the

tractor when it left the factory. Ascertain the indicator letter (A-G) of the existing oil sight-glass by referring to Table 1.

Ascertain the indicator letter of the required sight-glass by finding the SRI of the desired tire combination in Table 1. If a new glass is required, refer to Table 2 for the part number.
