Has anyone tried to install the rockshaft control lift arms from a 4000 series compact tractor onto the 110 TLB to gain more width when hooking up implements? If you look at the 4000 series rockshaft arms they have an angle outward to them where as the 110 TLB arm is straight. And I understand why JD did this, because of the backhoe mounts and the power beyond connection point. But I have noticed it is very hard on some implements to get the draft link arms to widen out enough to clear the implement pins when attaching. I have owned a 4000 series and never had this problem. That is when I noticed what JD did to the rockshaft control lift arms. Anyone experience any of these issues? Will the 4000 series rockshaft control lift arms fit the 110? The mounting end looks the same on the JD parts diagrams.

I think that there might be some confusion of "terms" here. So, I'd like to know if you're talking about the draft link "lift" arms or if you're talking about the draft link arms??
The lift arms are interchangeable. I purchased the right side lift arm for the 4000 series - the adjustable one - to replace the hydraulic tilt cylinder on my 110 when using my Kuhn disc mower. Works just fine.
If you're talking about the draft link arms - the lower "flat bar" - draft arms.... well, they're different and then again they're not!!
If you go here:
John Deere - Parts Catalog
You'll see that the draft arm (29) for the 4720 is so similar to the draft arm for the 110 here:
John Deere - Parts Catalog
they're similar enough that they're interchangeable. The lower links for both machines are slightly bent at each end. The sway links are different, however.
But, if you look at #243 on the 110 parts - the lower link is more angled and the sway linkage is a slider/pin arrangement. When you look at the parts breakdown for the 4720 at #372: the lower draft link is also angled and the sway linkage is a slider/pin arrangement.
So, depending upon the serial number for the 4000 series and the 110; you can find either the angled lower link or the straight lower link. And, both machines have a slider/pin arrangement for the sway links.
Short story - want the angled - gotta go with #372 on the 4000 lower link and #243 on the 110 lower link. The angle is not exactly the same but likely a workable solution.
Same story with the straight lower link. Look at #371 on the 4000 machine and #244 on the 110 lower link.
IMO - the more problematic concern is the sway linkage. Whether the rear attachment pin is the correct size to fit the mounting bracket that is bolted to the rear axle housing.
