Knob
Genuine Mtd part
By: Mtd
Part Number: 720-04061

This knob is an OEM replacement part for MTD power equipment. The seat knob is responsible for adjusting the height of the seat to ensure a comfortable and safe position for the operator while using the lawn tractor. It is usually located on the side or the front of the seat and is connected to a shaft or linkage that controls the seat height adjustment.

Causes of a bad knob can include regular wear and tear from frequent use, exposure to harsh weather conditions, or accidental damage. These factors can lead to the knob becoming loose, cracked, or broken, making it difficult to operate the equipment effectively.

Symptoms of a bad knob include:

  • Difficulty in turning or adjusting the knob
  • The knob slipping or not staying in place
  • Visible cracks or breakage
  • The knob falling off during use

This MTD replacement part is also compatible with other brands and models within the MTD family, ensuring broad applicability for your outdoor equipment needs.
