Things You'll Need
New motion drive belt
New mower drive belt
Craftsman DLT 3000 riding mowers make it manageable to have a large lawn. They allow you to cut the grass quickly and efficiently. After two years of mowing, the deck belts need to be replaced, as the belts will become misshapen from time-honored wear and tear. In order to safely replace the belts on a Craftsman DLT 3000, you must first remove the mower deck.

Disengage Clutch Belt
Position the attachment clutch deck into disengaged position. The clutch is located under the steering wheel.
Drop the Deck Lift
Position the attachment (deck) lift to its lowest position. The attachment lift is the large lever on the right side of the deck. Place it as forward as it will go.
Remove Engine Pulley Belt
Remove the belt off the engine pulley. The engine pulley is located directly under the engine. Pull the belt that is wrapped around it.
Remove Retainer Rings
Remove the retainer rings, anti-sway bar connecting the deck's center to the mower's frame.
