If its edges are already dull, it can lead to longer mowing time and frayed and torn grass blades. Mulching blade installation is easy. First, unplug the spark plug wire. Then, position the lawnmower on its side. Get a woodblock, preferably 6 x 2 in size, and put it between the old blade and housing deck. Make sure that the wood will prevent the old blade from moving. Take a socket wrench and remove the blade’s nut and washer. Remove the old blade and put the new mulching blade in. Put the nut and washer back and tighten until it is secured. You can use the woodblock to prevent the replacement blade from moving when it is tightened. This mulching blade replacement s an original MTD product.

A flange nut's unique wide flange design distributes the nut's pressure over the part it is securing. In return, it creates an even fastening surface, which reduces part damage and nut loosening. This one-piece all-metal fastener has a lock nut version that features a protruding circular flange. This drastically increases bearing surface, compatibility either for irregular or oversized holes, and surface tension reduction. Flange lock nuts are the preferred type of fastener for many lawnmower models because it can provide better fastening than regular screws, which are known to loosen under extreme vibration. However, it’s important to know that flange lock nuts are susceptible to wear and tear due to constant vibration exposure. It is essential to replace the broken flange lock nut immediately to prevent serious damage to the lawnmower.

A side discharge chute is engineered to move the debris away from the machine's underside. This is because grass that is not only long and thick but also moist can get trapped and clog the deck and the blades. When this happens, you will have to stop to clear the accumulated clippings periodically. To mitigate clogging and maximize cutting, using a side discharge chute is ideal. When a side discharge chute is installed, but clogging still occurs, there might be a problem with the chute itself. It can be torn or already loose. Luckily, installing a brand-new side discharge chute is easy and will take less than 5 minutes. Start the installation by removing the spark plug. The engine should be cool to the touch.

This replacement chute is an authentic OEM part for a lawn mower. The chute attaches to the side of a lawn mower, and as the blade cuts grass, it pushes the clippings towards the chute. The chute then sprays grass towards the back and side of the mower. These clippings can be left as nutrient rich compost for the lawn or the operator can go around and pick up the clippings for a stately, professional look. Chutes are made of a durable reinforced plastic, but because they are attached on the outside of the mower and protrude to the side, they can easily be rammed into trees, walls, and other obstacles. If hit too hard, the chute will tear off and grass will spray unevenly across the lawn. Fortunately, chutes are easy to replace. This repair will only require a socket wrench for disassembly and reassembly. As a top-quality replacement part, this chute comes sourced directly from the original manufacturer. It is compatible with Craftsman and Troy-Bilt lawn mowers. This part does not include any of the hardware required for assembly. Therefore, be sure to not lose the bolts removed during disassembly.

This blade adapter is made to attach a lawn mower cutting blade to the drive shaft of a push mower. Though it is made of sturdy metal and is tightly fastened to the mower's drive, the adapter and blade may wear and loosen over time. This can present a dangerous situation as well as poor cutting performance for the blade. Also, each adapter has a small insert tab that fits into the blade attachment. This tab, called a “key,” is actually a shear pin. Should the blade strike a solid object, the key will sheer off, preventing the blade from coming loose or suffering irreparable damage. The solution to either of these problems is to replace the blade adapter. The blade itself should be closely examined to make sure it fits the new adapter with no wobble or slack. To replace the blade adapter, turn the mower on its side with the air filter on top. Use a ratchet to remove the bolt that attaches the blade and adapter to the drive shaft. Make certain to fit the new adapter key into the keyway on the shaft. Always use a replacement part like this one, that is OEM certified to be identical to the original. This blade adapter is compatible with Ryobi, Yard Machines, Yard Man, Huskee, Cub Cadet, Troy-Bilt, MTD, and Bolens mowers.
