MAINTENANCE
BLADE TIMING AND ROTATION
(Mnt-R-0102)
Blades on multi-spindle mowers overlap cutting paths to ensure a complete cut across the width of the mower
and to compensate for blade tip wear. If a gearbox has been repaired, a blade carrier or side driveline has been
removed, or other maintenance performed which altered the factory set blade carrier timing, the blades must
be re-timed to ensure they will not collide while rotating.
BLADE TIMING PROCEDURE
1. Raise the mower to minimum height to allow sufficient clearance between the mower deck and ground to
visually inspect blade carriers.
2. Completely shut down the tractor and secure the tractor in position by placing the tractor in park and
setting the parking brake. Securely block the mower at this height.
3. On a side gearbox, remove connecting driveline coupler.
4. Manually rotate carriers until blades are positioned at near 90 degree angle from one another. See Fig.
Mnt-R-0102
5. Replace connecting driveline and coupler.
6. Manually spin carriers a complete rotation to ensure blades do not collide with one another.
