Boomer 30 broken stabilizer mount

[mnfarmer]

We have a similar problem with repeated bending and breakage...but unable to replicate JKott's situation. My husband says he wasn't able to get it to bind up. Any other ideas?

Can you post a picture of your pin and mount?


If the pin has a non flat surface against the stabilizer, then try rotating the pin while lifting the arm to see of it catches.

You can see in one of my pictures where the pin is bent and the mushroomed head on the lynch pin is visibly scraping and binding. You can also see contact marks on the stabilizer arm.

If you are bending because it is binding or catching, you will see signs of it on the pin and/or the stabilizer.

If its not binding, then maybe it is something else like turning while an implement is in the ground or bumping into something less movable than the arm like a tree?

Can't say I have completely solved the issue, but I put in several food plots and spread a hundred yards of gravel with the box blade without bending anything else.


There is invariably some slack in the rigid stabilizers. Assuming you have changed the pins so it doesn't bind when lifting, I found it was bending partially because the slack let it compress on one side, before pulling on the other. When I setup the stabilizers now, I push the implement to the side and make sure that one side pulls on the mount before the side is being compressed. Thinking about it, "pulling" straightens the bar. Compressing the stabilizer forces it to give in the form of a bend.

The other thing I did was take the bar assemblies apart turn them around. I put the female end that is stronger with the box construction down by the lower mount where it has been bending.



After initially bending it at 6 hours on the clock and blowing apart the mounts before 30 hours, making these slight changes in behavior I've put about 90 hours on the tractor, most of it using a tiller in very rocky soil or box blade and its been pretty solid. That, or it is because I bought a spare stabilizer.

I ended up having two things break or bend, depending on the thickness of the weld and the tolerances in the pins.

On the left side, the stabilizer bar could not slide by the pin and it completely bent it ($80 assembly, bent part not available for order separately).

On the right side, the stabilizer bar was able to slide by the pin and it became a wedge and blew the end off the stabilizer arm pin ($120 part)

The ultimate problem is the wrong pin was used. Here are close up pics of both my tractor and the one sitting on the dealers lot. Having one at the dealer with the same problem made it very simple to get the replacement stabilizer and the mount covered under the New Holland warranty. Notice when the pin twists, that the bar cannot slide past it.

The solution I have found so far is to simply use a different style lynch pin. In this pic, the center one is the one delivered with the tractor. Notice the fat head that overlaps the round part on all sides (the center pin is flipped over compared to the other two, but it overlaps on all sides). The overlap is what is catching on the bar and causing the problem. You can clearly see where it is rubbing, grinding, and catching. I was checking everything else on the 3pt system for binding, but never thought I needed to check this part. Not to mention when the pins are straight they don't necessarily catch. When they vibrate and rotate is when they catch the corner the most.

The solution is the 25 cent pin I picked up at tractor supply (right--I dug through the bulk bin to find the smoothest ones) or the heavy duty pin the dealer shipped me on the (left). Notice how both of these are ground down and flat on one side.

Thanks for your post with pictures. I already spent the $ awhile ago to replace my stabilizer bars on my Boomer 35. Just changed 3pt. attachment which got me thinking about them bending again. Researched TBN and came across your post. So I just changed my pins. Thanks a lot for all your help. Enjoy your Boomer!
