What to do if blades vibrate when engaged on my DR PRO Lawn Mower?
- Ddonald96Sep 2, 2025
If the blades vibrate when engaged on your DR Lawn Mower, the blade carrier mounting bolt may not be tight enough. Tighten the bolt as tight as possible by hand with at least a 1ft long 1-1/8" wrench. A swinging blade may be too loose on the blade carrier, so re-tighten the swinging blade mounting hardware.
