My woods brush hog had a bad vibration when cutting brush. In this video I determine the cause, fix it and test it out!

    Thanks so much. This is what I was planning on doing to mine. The blades aren’t swinging as freely as they should. 👌🏼
  • Good Video! I recently got a Milwaukee 1/2” Drive Feul Impact wrench. Makes it really easy to loosen up the Blade nuts compared to all the years I used a breaker bar! Have a 4’ B/H Squeeler with 1&5/16” nut with no key. The round bolt head Has to be held with a pipe wrench
  • I have the very same cutter with the very same vibration. I will do the same repairs you did this spring. When mine started vibrating I stopped the cutter then restarted it and it smoothed out again until I cut something like a 1 or 2 in. tree limb.
  • Thanks, I'll try to remember Your video. Mine has only a couple of uses over the 2 years I've had it. I mostly use the Loader, Box Blade & Forks, SO FAR. Ken
  • It’s best to be at low idle when you engage your PTO
  • I’m going to try this on my brush hog to see if it helps. I pulled the stump jumper off and the spline shaft has some play. Any idea if that’s normal or should it be totally rigid? What size nut is holding the blades?
  • Just FYI, a 4 ounce difference between the tips of the two blades on a 6' mower will result in 73 pounds difference in centrifugal force at 540 RPM (61 pounds for 5'). Losing a little more metal on one blade than on the other won't matter much, but a slightly different radius caused by a gummy pivot point will make a huge difference.

    a very well explained how to video... thanks...:) i wonder how much vibration is ok before the equipment tears itself apart?
  • One of the main vibration causes is the weight of the blades have to be the same. A 2 oz difference can cause it to vibrate really bad.
  • You screwed up big time, most Bushhog blade bolt nuts are one time lock nuts, each time you remove the nut is should be replaced with a new one. Most vibration I have seen comes from worn gear box bolt holes.
