IMPORTANT: When sharpening blades, be sure to grind the

same amount on each side. Unbalanced blades will cause

excessive vibration and could cause the spindles to wear

prematurely.

Check the blade balance by inserting a horizontal rod

through the center hole of the blade. The heavy side of the

blade will drop down. Sharpen the heavy side of the blade

until the blade is balanced, see figure 28.

After sharpening, install the blades back onto the mower

deck. Make sure the wings are facing up. Reinstall the blade

bolt and Iockwasher.

CLEANING GRASS BUILDUP FROM DECK

CAUTION: Before cleaning grass buildup, be

sure the engine has stopped and the key has

been removed.

Cleaning the underside of the deck regularly will help

maintain deck cutting efficiency. Clean the underside of the

deck as often as possible.

To gain access to the underside of the deck, depress the

deck lift foot pedal and lock it in the transport position. Move

the deck cut height adjustment to the highest setting. Raise

the front of the power unit and support it with jackstands.

Clean out any grass buildup from under the deck and

discharge shield. DO NOT use high pressure washers or

sprayers.

BELTS

Inspect the belt pulley grooves and flanges for wear. A new

belt, or one in good condition, should not contact the bottom

of the pulley groove. Replace the belt when the belt touches

the bottom of the groove otherwise the belt will slip

excessively.

Always use caution when changing a belt. Never pry a belt

on to a pulley.

Always keep oil and grease away from the belts and never

use belt dressings.

Belts should be checked regularly, and replaced at

approximately 250 hour intervals. Belts should also be

replaced any time the belt(s) show evidence of cracking,

missing pieces, friction burns from slipping, or other extreme

damage. Small cracks or fabric polishing are normal.

Small branches and other similar debris can get onto the top

of the deck, into the pulleys, which may cause the belt(s) to

break or come off the pulleys. Make sure the area to be

mowed is cleared of this debris, and make sure all belt

guards are in place, before mowing.

To guarantee long belt life, always use genuine Ariens belts.

WARNING: Most service work requires the

engine to be shut OFR To prevent injury while

working on the mower, remove the ignition key

and disconnect the negative (-) cable from the

battery.

1. With the deck in the transport position, raise the floor

pan. To disengage the drive belt, latch the tension arm

in its deck bracket. Roll the drive belt off the idler

pulley.
