MTD lawnmowers need maintenance after years of cutting the lawn, carrying brush and ploughing snow. MTD makes replacement parts for its lawnmowers. The cost for these parts ranges from £13 for a blade to £45 for a tire, plus shipping. These parts are easy to put on and will help preserve the mower.

Drive Belts

The drive belts are divided by the deck size--the longer the deck is, the bigger the belt it needs. Thirty-eight-inch decks need belt 954-04062. Forty-two-inch decks require the belt 954-04060B. Forty-six-inch decks require two belts. The upper drive belt is 954-04142, and the lower drive belt is 954-0349.


Each deck size requires a different blade. Thirty-eight-inch decks take blade 942-0610A. Forty-two-inch decks take the 942-0616A blade. Forty-six-inch decks need two blades. The centre blade is 942-0612A, and the outer blade is 942-0611A.


Front tires are sized at 15" x 6" x 6". There are two different connectors, round and square. The round shoulder is 734-04240A. and the square shoulder is 734-1731. Rear tires are 20" x 8 x 8 and are separated by the round and square version as well. The round shoulder is 734-04241 and the squared shoulder is 734-1730.
