Scotts riding mower belt diagram 42 inch

If the belt that drives the blades on your Scotts S1642 lawn mower is slipping, it’s time to replace it. Worn belts stretch and don’t make sufficient contact with the pulleys to spin the blades. It’s easiest if you first remove the mower deck before replacing the belt. It sounds like a long process, but the entire installation only takes about 30 minutes.

  1. Park your Scotts S1642 mower on a level surface, such as a concrete garage floor. Engage the parking brake, turn off the engine and remove the key.

  2. Place a wooden block under the mower deck on each side. Move the deck lift lever to its lowest position so that deck is resting on the blocks. Before placing blocks under deck, ensure no parts on the mower are moving.

  3. Locate the engine pulley. Pull down on the left side of the metal belt guide, attached to the engine pulley, to remove it from the bracket. Swing it out of the way. Remove the belt from the engine pulley.

  4. Disconnect the blade drive lever from tractor frame by removing the cotter pin and washer from the tension rod near the front of the mower deck.

  5. Remove the left-front draft arm on the front of the mower by removing the cotter pin and washer on the end of the arm nearest the mower deck. Pull the arm out through the front axle bracket. Repeat for the right-front draft arm.

  6. Remove the left-rear draft arm on the rear of the mower deck by removing the cotter pin from the bolt-like pin holding the draft arm to the tractor frame. Repeat for the right-rear draft arm.

  7. Move the mower deck lift lever to its highest position so the rear draft arms, attached to the tractor frame, are lifted up out of the way. Pull the mower deck out from under the right side of the tractor.

  8. Note the routing of the mower deck belt. Snap a digital photo to help you recall the correct configuration.

  9. Remove the belt guard located on top of the mower deck, by removing the cap screws from the guard with an Allen wrench. Decks that are 42-inch have one belt guard and two cap screws. Decks that are 46-inch have two belt guards and six cap screws.

  10. Remove the belt from around all pulleys on the deck.

  11. Install the new belt in its proper route.

  12. Replace the belt guard(s) and reinstall the mower deck in reverse order of how they were removed.
