I posted here last spring about a Jinma backhoe we found and bought for $800. It was a subframe hoe and we needed to mount it on our 1953 Ford Jubilee with 3 pt hitch. With some photo help from a couple guys who posted on TractorBuy that did something similar to this, it is finaly done.
My 85 year old father did most of the fabrication and plumbing, but he fell a couple months ago and does not get around to well yet. I finished it with help from a couple freinds that are good welders. I made brackets and mounted the counter weight today, except for paint its done.
Not the perfect machine but to maintain our water line and do a few odd jobs around here it will work very well. It digs in hard clay with no movement to the hitch, no nasty cracking sounds in our mountings etc. Once we got the subframe cut off and mounted the first time, we needed to beef things up a lot, so it became a whole new project...We even found and bought a new control valve block, which works very well now for this type of hoe. With practice its a decent digging little backhoe.You want to take it easy on the slamming around when in transport mode with that tractor, but it seems to handle it ok. Here are some photos.

I think you're gonna break that tractor, sorry, it doesn't look like it's meant to take that on the top link.

Absolutely! That 3PH was never designed to take the loads a backhoe will impose on it. It's not a question of "If", it's a question of "When" it will fail.

It would have, But not now. No movement, digs fine in hard ground. It might see a couple hours a year if that.
If it was going to break that top link bracket it would have when I dug for an hour or so straight in heavy clay today just to see how it held up. I dug as deep as the machine would dig and heaping buckets, full extension, prying out junks of clay, etc. I run heavy equipment for a living, and I can assure you it will do what we want.That top link bracket is pretty well beefed up.The slamming of transport of a heavy mower, cultivator, etc causes much greater shock loads on that steel casting than the straight push or pull of that hoe when digging. I wonder how the other guys that mounted them the same way feel about it... any pictures of failure to a top link bracket with a draft control spring on it?
