ADJUSTMENT
Test Mower Blade Stopping Time
(Figure 25)
To determine if the PTO stops the mower
blades within 5 seconds or less, measure the
amount of time from when the PTO is shut off
to when the PTO belt stops rotating.
1. Lower mower deck to the lowest position.
2. Start engine and set throttle lever to
FAST.
3. Engage PTO to start mower blades.
4. Shut off PTO and simultaneously start
measuring the amount of time it takes for
the PTO belt to stop rotating.
• If the PTO belt stops rotating in 5
seconds or less, the electric clutch does
not need to be adjusted.
CAUTION: Use care when releasing
idler spring tension. Keep body parts
well away from idler when performing
this operation.
