My Brush Hog is Shaking Like it's the End of the World

[@damonr2233]

Curious to know how much up and down movement to expect where the blades meet the stump jumper

[@johhlocke1687]

Thanks guys for the excellent information. You answered my question about the wobble within my bushhog going to tractor pto. The bearings are worn out and the reservoir was empty. Learn as you go.

Thanks for sharing

How much vibration is too much? I have a pretty good vibration that seems to mostly dissipate after getting cutter up to speed and while cutting. But it’s definitely noticeable when first starting. Any insights? Thanks, as always, for the helpful info!

[@TractorMike]

That sounds normal. Things shake a bunch as the blade pan and blades get up to speed.

[@johnbirman5840]

Yep. Just started brush hogging for the year. Vibrating too much. Didn’t do anything different than end of season, checked blades, one a little gummed up with old weeds. Cleared It out, put a. Little grease. No vibration. Off we go. Thanks.

Thanks guys!

Thanks Mike, this helped me troubleshoot my brush hog issue.

[@comlbbeau]

I might add, and you've mentioned it, the gearbox mounting bolts should be checked for security as well in the event of vibration. Good points.

[@larryhewitt1078]

Sometimes the gearbox’s bolts can come loose from the deck so always keep an eye on them and keep them tight!

I have an issue with my Brush Hog. It has less than 10 hours on it and it is new. I have a vibration issue. I checked the blades and they were not moving around freely. They seemed like they were too tight. I will find out this weekend if something is caught under the blades. I don't know yet though.

My JD MX6 is wobbling bag. The pto clutch is Hitting the housing. I pulled the stump jumper and can't find much damage. Mayne the blades are damaged. I will buy new ones. Can the gearbox be replaced?

[@TractorMike]

Yeah, but they're pricey! When you figure labor and everything it doesn't take long to get a big chunk of the price of a new cutter in an old one. Maybe time to trade?

[@henrybarrow1]

How about some information about fixing the gearbox and testing the u-joint ?

[@ioe12]

Is there a certain way to time the two blades or gearboxes so they don't hit each other or cause a vibration

[@csedan510]

I did a weld repair on my stump jumper, I had cracks around the holes where the bolts hold the blades. I removed the blades, welded and ground them, then took 2 pieces of . 065 ( both 6"x6" square) punched a hole and welded those over the fixed area. On reassembly, I have a little wobble through the steering wheel. What's the best way to balance?

[@lmfarms4611]

grass builds up between the blade and bolt preventing the blades to spin, how do I prevent that from happening?

[@richardvaldez2181]

I have a 10 foot rotary cutter by Kodiak it’s borrowed the blades are interfering with each other, I am bolted one of the driveshaft and rotated it half but it still seems to line up should the two blades come together at all or is the blades that are on or too long?

[@TractorMike]

The blades should not contact each other. That'll make a heckuva racket when you engage the PTO. Sounds to me like the wrong blades.

[@GPOutdoors]

Thanks Mike! Good video. Cheers!

[@toddbollinger7667]

That made my day. " You about cut my head off" LMAO

[@loganyoutube4818]

The castle nut pin can come out and the castle nut can back off and let the stump jumper wobble too

[@martypapanek8858]

My bush hog is scalloping (cutting lower on one side). Is this due to an inbalance?

[@BrucesShop]

Thanks Mike.

[@jacobc5757]

Tractor Mike - You forgot that it may have lost a blade or broke a blade. Also, if the blades get a foreign object wrapped around them! This could cause a vibration! I had experience with a stray water hose that was left out in the barn yard and it was picked up by the blades in the tall grass. You have did previous videos I know. But still, a new tractor owner might not know!

[@cogreza]

on my bush hog 160 the blades hitting each other like crazy, they started after a cut a mesquite tree around 2 1/2 in diameter

[@HeritageFarmsTexas]

Outstanding video. Good info

[@txtpqb]

Can a PTO shaft between the tractor and gear box that has play in the slide cause a bad vibration too? Just wondering if mine is the blades are uneven and/or the shaft is too loose where they slide in and out of one another? thx

[@Dan-oz4qb]

Quit your whining Mike close only counts in horseshoes and hand grenades. Your head is mostly still attached. 😕

[@chevyon37s]

We’ve had a seal go bad on our old HX15, oil leaked out. Killed the lower output bearing but instead of a vibration it snapped the bolt holding the stump jumper on and the whole stump jumper and blades fell off. Luckily I shut it off quick, and with new bearings, seals, and a new bolt it was good to go.

[@bendigr]

blades sharpened unevenly will cause a vibration.

[@txtpqb]

how did you correct that and come to that conclusion?
