Deines lawn mowers are zero-degree-turn-radius mower with forward mower decks. They cut grass like any other ZTR mower. The mower deck on the Deines mower has pulleys mounted inside that guide the belts that spin the mower blades. Each pulley has a bearing, and these bearings wear out over time. The bearings in this case are cylindrical or doughnut-shaped devices that hold the blade shaft in place and facilitate rotation. Replacing the bearings in a Deines mower deck will get the mower back in peak condition.
Turn off the mower and lift the hood. Place four wood blocks on the floor in front of the mower. Pull up on the mower deck to disconnect it from the rest of the mower. Pull the mower deck forward and remove the rods from either side of the deck. The rods should slip off their spindles easily. Set the deck down on the blocks.
Turn the pulleys inside the Deines riding mower to see which ones need replacements. Only the ones that squeak require replacing.
Unscrew the bearing from the top of the pulley with the socket wrench. Remove the belt from the pulley and lift the pulley and washers off the spindle. Use the wrench to remove the bottom bearing.
Place a new bearing on the bottom of the spindle and tighten it with the wrench. Place two drops of machine oil on top of it.
Place the pulley and the washers back on the spindle. There should be a washer between each pulley and bearing. Slip the belt over the pulley. Tighten the new top bearing over the washer with the socket wrench and place two drops of machine oil on the bearing.
Lift the mower deck from the wood blocks and slide it back onto the mower body. Place the rods back on the spindles in the side of the mower deck. The deck should click into place.
