Mower Deck Vibration?

[Nuru]

If your mid mount mower deck vibrates at high rpms (engine 2700 rpms), Is that a balance problem or are the rpms just too high?

 

[golfer]

It could be that one of your blades has been broken off at one end. This will cause one side of the blade to be heavier and vibrate.

 

[Nuru]

So it is probably related to an imbalance?

Check your blades. If they are chipped, etc that will cause your problem.

 

[Nuru]

Will do!

Grab one end of the blade and wiggle it up and down to see if there much play,if so you may need to replace the bearing in the housing,also check to see if the blade has been sharpen even.

 

[Nuru]

Will do, I will check all of that and maybe replace somethings like the bearings and the blades or get them sharpened professionally.

Mower blades can get a grass build-up on them.After a while this build-up can start to take the blades out of balance.Before sharpening,I try to clean off the build-up,then sharpen and balance the blades.The best way to have a bearing fail is to run unbalanced blades.

Me, too, with the wire wheel on the bench grinder.

if your blades are properly balanced, and you have done everything the others here have suggested, and you have greasable spindle, pump up to 25 skirts into each spindle, or as much as you can before the grease comes out all over the place.

if that does not help, time has come for either you or your dealer to check out the spindle for damage. DON"T CONTINUE TO MOWE, the thing will not go away "by wear and tear".

good luck

Nuru;
All good tips, also don't forget to check your belts for damage, they can cause some bad vibrations also!

 

[Nuru]

bubenberg; This vibration happens when the mower deck is raised up to mow high, instead of low. I will perform these checks to locate the problem. Thanks

 

[Nuru]

Thanks Zemek!

Nuru:

Does your mower have any u joints on the drive line? If so perhaps looks at these if it only vibrates in the raised position.

Might have to adjust the waste gate on your Turbo too.

Thanks i don't think it does but I will check. The wastegate, hmmm, i guess when I finally put it on (the tubo), i will have to check that too!

 

[Nuru]

Isolated; Vibration occurs at highest setting for mowing. Could this be ujoints, shaft or just incorrect adjustments?
