A carriage bolt is a type of fastener. It features a smooth rounded head and a square domed top. It has threading, which leads to up to the square shoulder. The purpose of its square is to prevent the bolt from spinning. Once the carriage bolt is inserted through the hole, using a nut and washer can provide additional security. Carriage bolts can corrode and loosen over time. Since it doesn't have a slotted head, a socket wrench is needed when replacing. This bolt carriage replacement is compatible with wood chippers, tillers, string trimmers, lawnmowers, and edgers. It is a genuine MTD product that measures 5/16x.075. It has a smooth rounded head and square shoulder underneath it. This carriage bolt is sold individually.

This scraper blade is an authentic OEM replacement part for a snowblower. Snowblowers operate using an auger that scoops up the snow and blows it to a different location. However, an auger cannot gather all of the snow because it would have to scrape against the ground. Scraping that auger against the ground would damage its blades and make them unusable. Instead, this scraper blade drags against the ground and collects any remaining snow so that the auger blades can remain protected. Scraper blades can be damaged if the snowblower goes over rocky terrain. Although it is nearly impossible for a blade to snap completely off a blower, the blade will leave the snow behind, making the blower less effective if chipped or dented. To replace a scraper blade, simply use a socket wrench to unbolt the blade from the auger housing. Be sure not to lose the bolts as they will be needed for reassembly. This part is compatible with Craftsman, MTD, Cub Cadet, Ryobi, Huskee, Yard Man, and Yard Machines snowblowers and is sourced from the original manufacturer. This part is a high-quality replacement part. It does not ship with additional hardware.

The friction wheel for a snowblower is sometimes also known as a friction disc or a friction ring. The friction wheel is what helps to move the snowblower forward. When the disc is in contact with the spinning drive wheel, the disc will rotate and turn the axle to propel the snowblower. Over time, the friction wheel can start to wear down or even break. If this happens, it will mean that the snowblower will move slowly, or that it might have erratic movements. Owners who find that they are having similar problems with their machine will want to check the friction wheel to see if it is damaged or broken. They will need to replace the disc before they can use the machine efficiently and safely. The genuine OEM replacement friction wheel is for use with snowblowers, and it is sold individually. Compatible brands include Cub Cadet, Craftsman, Troy-Bilt, Yard-Man, Montgomery Wards, Bolens, Huskee, MTD, Yard Machines, and Ryobi.

In a snowblower, the driveshaft is connected to a part called a worm gear. The worm gear turns the auger blades which eject the snow. The worm gear is connected to the worm shaft, which causes the auger blade to turn rapidly. Eventually, the incredible torque inside the machine, plus the occasional bumps and bruises experienced by the machine in operation and when being stowed, may cause the worm gear to malfunction. When the snowblower is erratic in its operation and fails to remove snow completely, there is a good chance the problem is the worm gear. To replace the worm gear, remove the housing to get to the worm shaft. Remove the entire worm assembly. Next, remove the blower fan and remove the worm gear. Grease the auger assembly before installing the new gear. Reverse the order to reassemble. While the snowblower is disassembled, it's the best time so exam the auger, driveshaft, sheer bolts, and tires for wear. You may find other parts that need to be updated. Make sure to replace the worm bolt and any other necessary parts with a genuine OEM manufactured part such as this one. This gear can be used in a number of snowblowers, including machines made by Yard Machines, Craftsman, Bolens, Yard-Man, Troy-Bilt, Cub Cadet, Ryobi, Montgomery Wards, Huskee, and MTD. Part sold individually.

This is a simple extension spring with an outside diameter of 0.38 and a slack length of 2.5. It is primarily used as an extension spring for snowblowers, but may be compatible with other lawn equipment. It’s designed to apply tension as the throttle is applied. The more gas there is, the more resistance will be present. Under most circumstances, replacement is easy. When the spring breaks or gets rusty, look at both points of attachment. Memorize where it’s attached, or take a picture, and remove the old spring using a pair of pliers if necessary. Install the new spring and the tool is ready to use. This is an OEM part sourced directly from MTD, and it is sold individually. It’s black in color and was initially designed for Troy-Bilt lawnmowers. However, because this is a versatile part, it has since been repurposed for a number of MTD and related machines in other brands. These include lawn tractors and snowblowers, as well as lawnmowers, in brands such as Ryobi, Yard Machines, Husky, and Cub Cadet.
