How to Troubleshoot Mower Blades That Will Not Engage

The blades of a riding mower must be engaged for the tractor to cut. When the blades no longer engage, inspect the mower for damage and defects. A few factors may cause the blades not to engage. Checking these things yourself can save a costly repair bill.

Things You'll Need

  • Deck belt

  • Metal putty knife

Step 1

Check the blade rotation control lever to ensure it is securely in position. Wiggle the handle to ensure it is not stuck between positions.

Step 2

Check the drive belt for damage or excessive wear. Replace if needed.

Step 3

Clean under the mower deck to ensure that debris is not clogging the drive shaft and that the shaft is not damaged or bent.

Step 4

Level the mower housing, making sure the blades are even.

Warning

Wear gloves when handling mower blades.
