A mulching blade has a unique curved or angled design that allows discharging, bagging, and mulching. 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. This OEM mulching blade can be used for MTD, Craftsman, Cub Cadet, Murray, Yard-Man, and Bolens lawnmower models. This brand-new mulching blade is sold individually. The support blade and screw hex are sold separately.

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. The MTD 712-04063 Flange Lock Nut OEM replacement can be used with Craftsman, White Outdoor, Yard Machines, MTD, or Columbia lawnmowers. It is a genuine or OEM MTD replacement part that measures 5/16-18. It is threaded and requires the use of a wrench. This replacement flange lock nut is sold individually. An MTD bolt carriage may also be needed and is sold separately.

The Lawn Mower Spindle Assembly is an OEM part for MTD lawn mowers Located in the mower's lower deck, the spindle assembly connects the blade to the drive belt. This enables the mower to cut grass effectively. This assembly is comprised of an adapter and a spindle. It gets activated as a pulley spins the drive belt. While designed to withstand minor impacts, larger or harder objects may cause damage. Damage can lead to blade misalignment or detachment.

You should replace the spindle assembly if it becomes damaged due to impacts with rocks, roots, or other hard objects, or if it wears out over time from regular use. A faulty spindle assembly can lead to uneven cuts, excessive vibration, and potential damage to other mower components.

Symptoms of a bad spindle assembly include:

• Uneven or missed areas of grass during mowing
• Excessive vibration or wobbling of the mower deck
• Unusual noises such as grinding or squealing
• Blades not spinning properly or at all

This OEM part is compatible with various brands under MTD, including Cub Cadet, Troy-Bilt, Yard Machines, Bolens, and some Craftsman models.

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. Then, lift and hold the mulch cover up. Take the brand-new side discharge chute and hook the tabs on to the hinge pins. Then, release the mulch cover. MTD manufactures this brand-new side discharge chute. It is an original replacement with Craftsman, MTD, Murray, Yard-Man, Yard Machines, Bolens, Huskee, and Mastercut lawnmowers.

This steering gear is an integral part of the guidance mechanism for riding mowers and lawn tractors. This gear meshes with the turning mechanism of the wheels, connecting the front axle to the steering column. The constant, short diameter turning of riding mowers puts a tremendous amount of pressure on the steering pinion gear as well as the steering plate, causing the teeth of each of these parts to wear out. Over time, the steering will become less responsive until eventually the drive wheels will not respond at all when the steering wheel is turned. This is usually an indication that the steering pinion gear is stripped and must be replaced. Replacing this gear involves removing the nut and bolt that fix the gear to the mowing housing. Often, the bushing that sits beneath the pinion gear also needs to be replaced because of wear, and this is the best time to do that, as well. It's also a good idea to see if the steering plate teeth are also worn, as this is the ideal time to replace it as well. All parts should be replaced with genuine OEM parts, manufactured, as this replacement part is, according the specs of the original part. This pinion gear is compatible with Huskee, Murray, Bolens, Yard Man, Troy-Bilt, MTD, Yard Machine, and Cub Cadet riding mowers. This part sold individually.

This is an oil filter designed to fit a variety of small, gasoline-powered motors used primarily on lawn equipment. This genuine OEM replacement filter removes contaminants that otherwise would wear down the internal working parts of the engine. While the filter works very well, it should be replaced annually as a part of regular maintenance. Depending on use, the filter may need to be replaced more often. When replacing the oil filter, the crankcase oil must be drained and safely discarded as well. To remove oil from the gasoline engine, start the engine and let it run for a couple of minutes. This circulates the oil and heats the internal engine parts so oil is better able to drain. Next, remove the drain plug located on the bottom of the oil pan and collect the oil. Remember to dispose of the oil safely where it cannot contaminate streams or aquifers. Once the oil has been removed, remove the old filter and discard it properly. The new filter should only be hand-tightened in place as using a wrench may cause the filter gasket to seal to the engine block. This filter will fit Yard Machine mower engines and MTD equipment.

A flange lock nut, also known as a flange lock or a lock nut, is created to be used in various types of lawn and garden equipment. This flange lock nut holds other parts in place and, when properly threaded, will resist loosening. Over time, a flange lock nut may begin to weaken and may become loose or break. If it appears to be broken or weak, a replacement is required. Flange locks can be adjusted and uninstalled after use. When replacement is required, you may need a socket set, screwdriver, hacksaw, and butane torch. The socket wrench will loosen the bolt it is connected to, while the torch is used to heat the lock nut. A socket wrench may remove the nut, but sometimes cutting it with a hacksaw is required. This flange lock nut is a genuine OEM component directly from the manufacturer and comes in an individual unit. It is made of metal, a gold color, and can be found in various areas of lawn equipment.

When interlock switches are working properly, they will keep the engine from starting if there is no foot is not on the brake or if the parking brake is not set. When the switch breaks, it will not allow current to reach the starter even when the brake is on, which means the engine will not start. If the solenoid is not clicking when the ignition key on the tractor or mower is turned, the interlock switch is likely to blame. This is a genuine OEM replacement interlock switch that can help get a lawn tractor up and running again. Is is compatible with riding tractors and mowers from many different brands, including Craftsman, Bolens, Yard Machines, Yard-Man, MTD, and Troy-Built.

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.
