Can anyone please show me there top link setup on a 45 with the newer seat! I have been trying to come up with something that actually works for a couple of weeks! I have tried to bolt something to the top bolts on the lift assembly but, apparently my ideas won't work, the bolts won't go back into the frame because of the closness to the angle iron I'm using!! I need some help!! PLEASE!!!! Thanks for any ideas or pics of your setup!!

I don't have any pictures, but I just welded some 1/2" steel brackets to the rockshaft. Cut them to match the curvature of the shaft and have the lift arms in the "up" position when you weld them on. Been using that setup for 15 years with no problems..... ....RP

Heres a plan for the ones I build. It clamps on to the rockshaft. Works better than the cheap ones you see for sale. It stays centered and doesn't dent up the rear differental cover. Let me know if you have any questions.

your plans look great, I have been looking to redo something for my top link is bashing into my rear cover. Thought it was because the top link was too long. But after checking some magazines and a few retailers, found them all to be the same length. I had just two questions, is the bracket you built on the rockshaft welded to the rockshaft? or is the rockshaft able to move freely? Nice job! Scott.

I've done them both ways, but I like it to move freely on the rockshaft.
There are always some problems incountered though when it rotates on the rockshaft. Like if you use a back blade with the tractor in reverse you get a forward force on your top link causing it to rotate up and over the rock shaft. But in the forward direction it seems to work a little better than having the top link rotate with the rockshaft. When I started building the this way, I was trying to figure out a good way to keep the toplink centered on the rock shaft. I was using the simple strap you see for sale everywhere, but it was alwas sliding sideways on the rockshaft.
I also built one similiar, but used 2" u bolts to attach it to the rockshaft. I bolted tight to the shaft and rotated with it.

I was looking at possible using a piece of 5 inch angle iron, attaching to the top bolts of the rock shaft, and the top two bolts of the rear cover with spacers, and the rear bolts on both brake covers, after cutting down the top side with the plasma cutter. Then welding the two brackets for the top link to that. this would give me a longer reach since my top link is adjusted in all the way, but still seems too long. will look at it closer when the rear end is done. and 3pt is bolted back on. Scott.

Something doesn't sound right. Your toplink connection would be higher and probably more forward than mine. I use a 20" top link (thats the distance between the pins when it closed all the way) and I use it about in the middle of its travel. I have some 16" top links which I use on another tractor.
What are you using for your lower lift arms. measure from the pins of the lower lift arms to the end of the PTO shaft. That may be too short and thats why you are having problems.

My toplink is 20 inch's, and adjusted all the way in, the lower arms are 34" center to center, and are attached to a cross piece over the draw bar directly below the transmission. The arms and this cross piece have newer paint on them so I'm guessing someone added this on. It looks like this cross piece (which is 3" angle iron with cat.2 pins welded on the ends) can be unbolted from the top of the drawbar and turned around, this would extend the lower arms out maybe 4 or 5 inches. Think maybe someone installed this piece backwareds?

Scott, Measure from the very rear end of the PTO shaft to a line between the ends of where the lower lift arms would attach to an implement. When I design hitches I aim for 20" - 22". If this is less, you could try a 16" toplink. I have seen some specs. on this measurement and will try to locate it.

shows to be 21 1/2 inches. add the 34 inch lower arms, and that makes 55 1/2 iches from the PTO to where the ends are. Is anybody elses that meas.?

can't post a pic, don't have a dig. camera, however I reread your request on the measurement from the PTO, and I read it wrong the first time. took the measurement from the stub shaft coming out of the PTO to the front of the lift arms and then to the back. My tractor is all torn apart right now so did some reassembly for measurements this am. from the end of the PTO shaft to a line running thru the lift arm ends as if it were attached is 15 inches. I think this is what you were asking before? you can e-mail if you need. thanks.
