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.
