Tighten mower blade hardware
Mower blades are sharp. For your personal
safety, do not handle the mower blades with
bare hands. Careless or improper handling of
blades may result in serious injury.
For your personal safety, blade mounting capscrews
must each be installed with a spline washer and a
spring washer, then securely tightened to 61-75 N.m
(45-55 ft. lbs.).
Mower blades must be timed perpendicular to each
other.
1. Make sure each blade (B) is installed with the tabs pointing
up toward mower deck. Use a wooden block (A) to prevent
blade rotation while tightening the capscrew (C) to 61-75
N.m (45-55 ft. lbs.).
2. Check that the mower blades (D) are positioned
perpendicular to each other. If not, perform the mower
blade timing procedure found in the “Regular
Maintenance” section.
