3.2 Mounting Mower to Power Unit
Step 1. Insert the tubes of the Power Unit into the matching brackets on the mower deck as
shown. You may need to manoeuvre the Power Unit into place by grasping the rear nerf bar and
wheeling it into position
Step 2. Secure the Mower Deck to the Power Unit with the provided locking hardware!
Step 3. Install the drive belt – which comes with the Power Unit - that goes from the drive pulley
on the Power Unit under the Motor to the driven pulley on the mower deck. In order to
accomplish this, follow these steps:
1. Remove the Deck drive shield
2. Loosen the 4 bolt and nut assemblies that hold the motor in place.
3. Loosen the 2 adjuster bolts at the rear of the engine plate.
4. Slide the engine completely forward to the mower deck.
5. Loop the drive belt around the driven pulley on the deck and thread it through the two
sets of idlers and place it onto the drive pulley beneath the engine. Ensure that the belt
is running in position and is not twisted, before tensioning.
6. Manually slide the engine plate rearward to put some tension on the belt and then
tighten it with the two tensioning bolts at the rear of the power unit frame.
7. The belt tension should be tight enough that by reaching beneath the mower in the
center section of the power unit, that it takes 7.5 lbs of pressure to deflect the belt 1/2
when grasped just below the opening in the covering plate.

belt routing between the
idlers on the power unit.
