SOURCE: Craftsman riding mower noise when blades engaged

With blades on and engine off reach under and wiggle each blade up and down. If you have excess play you will need bearings.

SOURCE: Craftsman zero turn - blades won't engage

The PTO switch contacts to operate the clutch that starts the blades is defective. I have replaced mine and the new one just failed again. Sears must know this is a defect problem but so far they are quiet about the problem

I have a John Deere LA145 lawn tractor. When I engage the mower, a loud noise (grinding) comes from the mower. What could be the problem? The tractor is 2 yrs old.


check and make sure all of your drive pulleys are spinning freely a bearing may be bad in one of the pulleys cause it grind metal on metal but the most common problem is a bent or warped mowing blade cause it wobble and shake and contact the underside of the deck.

BLADE DRIVE BELT ADJUSTMENT


Well, most riding mowers have a "pully idler", meaning once you have the belt on there (and it is the RIGHT size), the idler automatically gives the belt tension when you engage it (in fact, the idler pully is what IS engaged when you engage the belly mower).

Couple things to check (super simple):

The Belt. Look to see if she is wore smooth out.
Sometimes....they WILL stretch on you, instead of busting/coming apart, and give you noise (when she is engaged, but wore out enough to flop around a little)

The Deck Blade Bearings. Straight away, that is what it sounds like, or bent blades.

Check your Blade Bearings (super simple):
1. Pick up your deck to the highest high setting (mower off, just sitting).
2. Reach under, and grab your mower blade (do this for both sides), and TILT your blade UP (meaning, don't LIFT the blade straight up).
Seriously, jiggle it at a TILT. If you feel some slack in the bearing, the bearing IS shot. Straight up and down is most of the time OK, IF it is VERY little play on your blade bearings. As you do it, look at your belt pulley directly on top, if you see that pully bobbing....

However, if you grab one side of the blade only, then tilt the blade up, and she moves.....
Bearings need replaced, both the upper AND lower bearings PER blade.

They are not hard to replace, and not expensive either! (Though unfortunately, most are "sealed" junk nowadays!)

Bad Bearings show up (make themselves known) in only a few ways: Tons of Noise (grinding, squealing) & Vibration.

Go check them thar Bearings!

Grinding when mower is engaged but no apparent damagewas found


You may have a bearing gone on one of the quills (blade shafts).

Remove the mower deck from your tractor,and check each quill for play in all directions. If there is any movement other than spinning, you will need to replace.
