Hi - I've recently bought a TL140 with 3000 hours from a rental yard, have put a 100 hours on it with a 4n1 with tilt, and a heavy duty grapple, and now I'm having problems with the backhoe attachment (same as 4n1 - loflin) staying attached to my tractor.
My neighbor had his tractor plates welded and material added so his backhoe would stay on, I could get that done, but the backhoe company is telling me sometimes customers will need a shim to weld onto the lower catch plate to take up some of the slop. When I yank on a stump, I see about 1/2 in to 5/8 of a gap on the bottom, and then the pins retract - so I did some research on the pins not staying down. Seems like Kubota has a rebuilt kit for their tractors with new shims?
I went out and took park my pins and handles - there's a short spring that holds the level to the pin arm, and a long spring that seems to want to extend the spring. I tried tightening that nut to make the spring more compressed but it seems like it's bottoming out and the short spring on the handle is bottomed out. That one looks well worn but the long one I can't really tell.
Does anyone know what right solution is here? Take a look at the video and you'll see the pin retract, a gap form at the bottom of the implement, both when yanking as a test. The bucket completely falls off if I try to use it. But pushing the grapple, yanking the grapple, etc. 4n1. etc. - don't have the problem. All the heights seem to be the same on the catch plates - about 16 inches - which seems like the specs on the internet, and the loader plates are about 15 & 5/8.
Also - the gap only forms when I tug, when the bucket is in the air and gravity is pulling it down, there isn't much gap - so it makes me think that a shim really isn't the problem. You can see the bottom of the long spring start to retract on the third and forth pictures.
