Test Mower Blade Stopping Time

(Figure 26)

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.

• If the PTO belt does not stop in 5

seconds or less, adjust the electric

clutch.

Adjust Electric Clutch (Figure 27)

NOTE: Ariens recommends having the

electric clutch adjusted by a professional.

Contact your Ariens dealer.

If the electric clutch fails to engage or

disengage properly, begins to make an

abnormal noise, or if the mower blade

stopping time is too high, check the air gap at

the three inspection slots.

Inspect air gap:

1. Stop engine, set parking brake, remove

ignition key, and wait for all hot parts to

cool.

CAUTION: Use care when releasing

idler spring tension. Keep body parts

well away from idler when performing

this operation.
