Grinding Noise Under the Cover

Mower was working fine then it began to make a loud grinding noise....blade still turned, etc. Removed the cover and took off the top motor including the magnets and vacuumed and cleaned with alcohol and q-tips. Noise still exists. Any idea on what's going on?

Possible armature shaft are wobble. to check if i am right see the blade end & mark a spot against the mower deck & do the same other end of the blade. if the blade are not align on the same spot then the shaft are bent.

I have a John Deere Sabre 38" 14.5 hp mower. It works fine at low speed but when you try to accelerate it makes a grinding noise


This could mean many things, innumerable possibilities, I will give you the most common, at low speed the blades will not wiggle unleveled as much as when they are accelerated, that grinding noise would, most likely, be your blades touching the sides or top of the protection shell or cover in your machine. Remove and level with those inexpemnsive kits and a grinder, also when you hit a rock, or in any case a root, while you are in use of your machine, this will slightly bend one side of the blade making it impossible to see by eye but when the blades spin, this will be very noticeable by the noise made. Good luck

Hi Josh, It sounds like you have a bearing going out on your deck. The best way to check is to remove your deck from your mower, and remove belt. Then spin one blade at a time, they should spin freely and fairly quietly. You will be able to verify the bad bearing quickly by isolating and checking one at a time. The noisy one that grinding will probably need to be replace, although you could try greasing it first. They are fairly simple to replace and not too expensive. It should consist of three or four bolts. FYI, you may want to take a picture of how your belt is routed before removal, this will help you when reinstalling it. Good luck and I hope this helped.

Won't Fully Engage Drive Gears


If the machine has been sitting idle for a period of time it is probable that the cutter spindles have failed / rusted bearings. They suffer from wet grass/ water seepage when working and when let stand idle for a time will rust up the balls in the bearings. Loosen the drive belts and see if the cutters can be turned freely by hand .

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.

Grinding loud noise in the transaxle


sounds like the bypass lever might not be re-engaging, push it in firmly. OR, the brake is sticking. this, of course, is if the noise is a growl or a groan. if it IS a grinding noise, look for something stuck in the trans cooling fan or between the axles and wheels, otherwise it's inside the trans and that's not good [re: replacement]

I would check to see if you can rotate the fly wheel by hand. Also check to see if the blade(s) move easily (with the mower off and key out get under tractor and try to rotate the blade if it moves freely then great if not then you have other issues). Report back so that we can go from there.
