Bush Hog Stump Jumper Removal

I hit a stump with my Bush Hog and it began shaking violently. The blades were not obviously bent or damaged, but there was a dent on the stump Jumper. I decided to remove the stump jumper which can be a major challenge. I created this video after I was able to remove it to share the technique I used along with a couple of mistakes. This is a SQ172 Bush Hog. The blade nut size requires a 1 11/16 " per the manual and I found that to be what I needed. I found that a 36mm socket fit the castle nut on the gearbox output shaft. I have now replaced the gearbox and bent the framework back into shape and the Bush Hog works fine without any vibration. The new gearbox, new blades and blade nuts cost $742.32 from a local tractor dealer. I also purchased some anti seize which I put on everything and I had to purchase the unusual sockets from Amazon.

I feel your pain, I took mine apart last fall to replace a rotted out jumper. Also, appreciate sharing mistakes as well as success! All the best in getting yours back together!

The main nut came off rather easily on mine. Now to apply some heat to try to break that splined shaft loose. Thanks for the video!

I have been working for 4 hrs and still haven't gotten the castle nut off. Thanks for the video.

I had to split the castle nut and the two blade nuts to get them off. You would think Bush Hog could afford a little never seize when they build them.

Thanks for the Laughs a 1inch Impact that you can Rent would have taken it all apart, and a Hydrolic jack is used to take the stump jumper off.

Replace the arms with chains. It works way better on uneven surfaces.

That’s the purpose of the stump jumper is to prevent shaft damage. I guess it wasn’t enough. My question is does that heat compromise the temper of the hardened parts?

Thanks for watching and your comment. I replaced the gearbox because the shaft was bent, installed new blades and blade bolts, but I put the same stump jumper back in. I have been using it regularly and have not had any problems. I originally tried using my acetylene torch to heat the stump jumper, but I found out quickly that even though the acetylene torch gets very hot, enough to melt the steel, it is too localized. The large propane brush burner torch enabled heating of the spline shaft and receptacle in the stump jumper without melting any steel parts.

I think a chain from your tractor to the three pt hitch would work better to turn it over. Problems multiply,dont they? There must be blood also for mechanical work. That top frame looks kind of flimsy. We mow alot of rocks where I live. We never bought a Bush Hog. We were lent a heavy duty JD mower once but I didnt get aggressive with the mowing because it was borrowed.

Thanks for watching and your comment. You are right about the top frame. This was a lower end model for a Bush Hog, but I have gotten a lot of use out of it.
