I have a HaulMaster QH, and 5 different implements for the 3-point system that all claim to be QH ready. News flash: no two of them are actually anything alike, meaning on 2 in 5 (the box blade and the chipper with some finagling on swap) actually fit the QH when I got it, That also required moving the top hook all the way to the bottom to hook the bolt and bushing on the BB with the top hole unused and the chipper was the most compatible with it. I already modified my cheap tow hitch (widened it to Cat II width) but it was still slightly aggravating to put on the QH because of the top hook placement. The various problems I ran into was different angles of the front frame on the different implements. Everything except the subsoiler is labeled QH compatible, but I guess that depends on whose QH you have.
So, yesterday, I did some measuring and cipherin’ and some gazintas and figured out the QH would work brilliantly on the chipper if I moved the hook up 3 inches (extreme top position and coincidentally the same distance between the two top link holes on the chipper). A little studying and I figured I could move the bolt and bushing on the BB to the top hole as well. That change made it much friendlier to connect with the QH. Next up was the LSR (landscaping rake). Hmmm, the diagonal braces on it are welded, but moving the bolt and bushing to the top hole would be close, albeit the front frame leans more forward and can’t move. The tips of the front frame hit the bolts of the top hook but otherwise it looked like it would work. Clipped the corners off, and BINGO, it’s super easy to connect now. I still have to get off the tractor to stow the storage stand, but I usually do anyway for a quick inspection before I use the implement.
Finally, I modded the tow hitch again to use the top hole and now 4/5 of my 3-point gear is actually compatible with my QH, and MUCH easier to connect. Took a few photos to show the changes.
Moved the top hook
Rearrange the top of the BB
And finally the rake
The subsoiler is gonna take a bit more welding and tweaking because it only has the lower top link holes and the top of the frame is welded.
