Genuine Mtd part
By: Mtd
Part Number: 732-0994

This extension spring is a genuine OEM part sourced directly from the manufacturer for use on lawnmowers. The extension spring is part of the idler pulley system that allows the idler pulley bracket to pivot when turning blades on and off.

Bell Washer
Genuine Mtd part
By: Mtd
Part Number: 736-0105

This is a replacement bell washer, a flat washer that can be used with a wide range of various types of lawn and garden equipment. The inner dimension of this washer is 0.40 inches, while the outer dimension is 0.88 inches. Washers are typically used as a way to help ensure a tight connection when used with bolts or screws.

This could mean they no longer provide a solid and secure connection. Other times, the washer could become lost while working on the machine. Owners should always be sure that they replace any lost or damaged washers right away. Not using washers can reduce the lifespan of the machine. This is a genuine OEM bell washer that is sold individually.

Drive System Fluid
Genuine Mtd part
By: Mtd
Part Number: 737-3121

This is MTD drive system fluid. Drive system fluid is designed for hydrostatic lawnmowers. These types of lawnmowers use hydrostatic pumps to use oil that moves through the pistons in the hydrostatic drive system. Hydrostatic mowers allow users to operate through a wide range of speeds instead of changing through preset gears. Typically, these mowers have more power and speed than regular mowers. Checking the dipstick or sight glass marker can indicate whether it's time to add more drive system fluid. The drive system fluid should be changed every 1,200 hours of drive-time. Remove the drain plug for the transmission system. Allow the old fluid to drain into a pan. After the fluid drains, remove the transmission sump screen and clean it. Replace the main hydraulic filter, and fill the reservoir to the recommended level written in the owner's manual. Let the mower run for about five minutes before using it to cut a full lawn.This product should only be used with Cub Cadet lawn tractors. No other parts or components are included with this product.
