Change Rear Tires

If rear tires have been changed since last successful seeding, inspect main drive clutch sprocket (B) to ensure tooth count matches new tire size. Tooth count is stamped into sprocket for easy identification.

NOTE: Add or remove chain links (as necessary) when sprockets are changed.

IMPORTANT: Maintain accurate travel speed, area, and application rate on monitor. Recalibrate tire speed sensor when tire size changes.

(See Monitor Setup section for sensor calibration procedure.)

Wheel hub and axle housings (A) are factory assembled to match original rear tires. Reposition (as necessary), if rear tire size is changed.
