Cub Cadet Lawn Mower Parts

Cub Cadet 21" Mulching Blade
Genuine Mtd part
By: Mtd
Part Number: 942-0741A

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.

Cub Cadet Flange Lock Nut
Genuine Mtd part
By: Mtd
Part Number: 712-04063

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.

Cub Cadet Lawn Mower Spindle Assembly
Genuine Mtd part
By: Mtd
Part Number: 918-04822B

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.

Cub Cadet Flanged Lock Nut
Genuine Mtd part
By: Mtd
Part Number: 712-04065

This is a flanged lock nut. It’s designed to apply tension, typically on a joint that needs to have a certain amount of flex. As such, it’s mostly used on snowblower chutes and lawnmower handles. They can remain in place, but with a forgiving connection that can take a beating. The nut size is 3/8, with a thread size of 16. A lock nut will generally last for many years. However, the silicone ring inside will wear down if it’s frequently tightened and loosened. It needs to be replaced when it will no longer reliably remain in place. Generally, this begins as a symptom of slight slippage and worsens as time goes on. Thankfully, whether it’s being used on a snowblower or a lawnmower, this nut is generally straightforward to access. Simply unscrew the old nut, then screw the new nut on until it’s nice and tight. Our flanged lock nuts are genuine OEM MTD nuts, and they are sold individually.

Cub Cadet Steering Pinion Gear
Genuine Mtd part
By: Mtd
Part Number: 717-1554

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.

Cub Cadet Flange Lock Nut
Genuine Mtd part
By: Mtd
Part Number: 712-04064

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. It works with lawnmowers, trimmers, snowblowers, cultivators, tillers, and leaf blowers by Poulan, MTD, Toro, Cub Cadet, Murray, Troy-Bilt, Bolens, Yard Machines, Craftsman, and Yard-Man.

Cub Cadet Interlock Switch
Genuine Mtd part
By: Mtd
Part Number: 725-04363

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.

Cub Cadet Brake Puck
Genuine Mtd part
By: Mtd
Part Number: 917-0678

This is a brake puck intended for use with lawnmowers. It is made from durable material and is part of the brake assembly. The purpose of the brake puck is to create pressure on the brake disk whenever the brake pedal is pushed. This part is essential to ensuring the lawnmower stops when a user presses down on the brake. Over time, the brake puck will start to wear down and may need to be replaced.One of the indications that the brake puck needs to be replaced is a squealing sound that occurs when the brake pedal is pressed. This happens because the brake puck wears down, and metal is able to rub against metal. If the problem isn't fixed, it can cause additional issues with the lawnmower. The brake puck should be replaced using a socket set and wrench set.This brake puck is designed for use in lawnmowers manufactured by Craftsman, Toro, Cub Cadet, Troy-Bilt, Murray, Yard Machines, MTD, Huskee, Bolens, Yard-Man, and MasterCut.
