I was scraping horse squeeze out of my trailer with my Branson Tractor that I adapted a Jinma Hoe to and the boom stopped lifting. When I checked the top eye of the lift cylinder broke apart. It has always dropped like a rock on the down stroke and if you stopped before bottoming out the boom would bounce real bad so I guess it finally caused damage.
I took the cylinder out, cut off the remaining metal with my Plasma cutter, made a new end on my lathe and welded it back on. I thought about trading the lift cyl with the dip cyl but my weld job looks stronger than the factory weld!
I also took an adapter fitting that I had to make to replace a hose on the boom cyl in the past and brazed it shut, then drilled a 1/8" hole to make an orifice so the boom won't drop so fast. It seems to work, I will know the first time I use it.
