Replacement parts for Dynamark lawn tractors can be purchased via websites such as DiscountOnlineParts.com, MFGSupply.com and MowerGraveyard.com. Dynamark lawn tractors are no longer made as of 2015, so contacting the manufacturer directly for parts is not an option. However, most of the necessary parts are still available and can be ordered online through various lawn mower parts retailers.
Discount Online Parts sells replacement Dynamark lawn tractor blades, control cables, deck belts and drive belts. As of May 2015, replacement blades range in price from a little over $9 for a low lift blade that is designed for 39-inch cut decks, to around $16 for a high lift blade that fits 42-inch cut decks. The website only carries one type of Dynamark deck belt. The belt is compatible with 38-, 39- and 45-inch cut decks and costs about $33. Their selection of drive belts is much more extensive and consists of 12 different belts that are priced between $9 and $46.
