I got some well needed chains this weekend for my JD 750 tractor. The snow is knee deep and I still need to get down to the firewood pile in my field. the tractor was getting stuck. so now I have the chains on.. they are catching the link hardware of my 3 pt hitch...they knocked the chains off once.. and another time caught and stopped my right rear wheel!!!....and they catch and it sounds like something is jamming....because the links and the 3 pt hitch assy sways side to side and I fight the snow... I have a back plade on the 3pt hitch. and I need to keep that on...its just that the WIDTCH of the back blade attachment spreads the links wide!!

anyone have a solution?

I guess the first option would be to see if your wheels are offset and, if so, if you have them installed in the "wide" position. That might give you a few inches which may be enough to resolve your problem.

If that won't do it, then perhaps wheel spacers? I know Bora makes them for the 790 but I'm not sure if the 790 has the same bolt pattern as your 750.

Can you swap the lower pins to the inside of your blade? Maybe that will narrow the lower links some and give you enough to miss the snow chains....

you can turn the pins so they face inward???????

the wheels are probably offset outward already....the are deep set looking from the outside!!

I was referring to reversing the lower lift pins on the back blade. Instead of them pointing outward (wide), can you flip them so that they point into the middle? Then you lower lift arms would not need to be as wide....

Sounds goofy, but plain old rubber Bungees between the draw bar and the limit chains, will keep them from flopping into the tire.

Take up more slop, to limit sway, and just hook a bungee on each. Had to go that route with our heavy back blade on the Ford 19120, that was doing the same thing.

Moving the Pins on the blade is a permanent fix if you can.

ETA:

Just noticed the upper lift arm link, is what you are having issues with, not the dangling links of the limit chain...
Gonna need to reduce sway to near zero if you can, or swap the pins around somehow.

yeah the chains on my links that are supposed to limit sway AWAY...are so long, they are useless... I think the problem is this: the WIDTH of the mount of the back blade is so wide! same goes for my York rake...so the link have to be spread to fit on... and there just isn't that much room in between the tires back there!!

I actually lost a pin that fits the drop bar to the link when the tire chain grabbed the clasp and removed it...then the pin fell out in the snow somewhere...

there is sway in the links when the implement is attached... I guess the chains from the frame of the tractor to the links are supposed to limit that...but the links are so close to start with to the tires and the chains are so long.... Id need like 2" long chains at the max to limit side to side movement of the implement....

I have to do something..i am going to damage one thing or the other soon....

I think my problems boil down to the fact that I bought UNIVERSAL 3 pt hitch parts, because I couldn't find the ones for my JD 750. And I dint want to pay $500 or so buying the factory parts. I think the factory links would come out close to the centerline and flare outwards AFTER the tires and then hook back to straight for the mount location...while my universal bars are mostly straight
