They made at least 2 arm styles. I have the thinner one here, I can try to get measurements on the other tomorrow evening or the next nite.

I'll try to do this verbally, if it doesn't make sense, let me know, I'll make a drawing.

Overall length of the bar is 19 3/4
Center of each hole is 3/4 inches in from end.
Center to center on the holes is 18 1/4
From the tractor end hole center to the lift rod hole is 9 1/4
Lift rod hole is 1/2 diameter
End Hole in the flat stock is 7/8 sleeved to 3/4
Sleeve length is 1 inch overall length.
Arm is 5/16 x 1 1/2"

Hope that makes some kinda sense, good luck and let me know if you need more info.

BTW, if you get all the measurements rounded up, if you wouldn't mind posting them or uploading them as a PDF as a drawing, that would be very helpful.

I picked up the lift arm for a 3-point and these measurements will help to make the arms. I can make a drawing given some time. Will see what I get.

By the way, are these 1 1/2" X 5/16" material or larger?

Kenny, I actually have both sets in the same place now. The set I bought from BHTS is thicker material all the way around. I will try to get this done tomorrow nite.

I drew up a little something. You left out the height dimension of the bar stock. I changed it to 3/8" X 2". Also changed the 7/8" bushings to 1" (1/8" wall). Check this out:SearsLiftArm.jpg

Center to center on the holes is 18 1/4
From the tractor end hole center to the lift rod hole is 9 1/4

I have been gathering more info. Got some dimensions for the lift links and top link. I hope to make use one on the GTV/16, but I am going to try to hook it to the mower lift handle. I don't have a mower for this tractor and it is spring assist. It does have an adjustment for how far down it goes.

when you build it, put a dog leg in it to widen it a bit so it can take both sears and regular Cat 0

At present, I do not have any 3-point implements. But, yes I would build it to regular Cat-0 specs. The main reason is I like the ability to lengthen/shorten the top link for bite on the implement.

Need more info. On the lift bars, what is the approximate height the arm ends are off the ground when up? I need this to provide clearance for the dog-leg to the 26" tires I have on this tractor. Also, can some one point me to where I can find weldable Cat 0 swivel ends? Thanks. Drawings are in progress.

when you say how high are the arm ends, are you asking about the lower arms or the lift arms? i assume the lower arm height is what you want. i just measured my non-adjustable side and got 18" at the end of the arm. this measurement may be a tad off because my tractor is in the yard and not on flat concrete. hope this helps and if you need anything else just let us know.

Yes, that is what I was looking for. Since I put the 26X12's on this, I need to have clearance for the tires at full lift. I hope to be able to be a Cat 0 width out at the ends, but won't have much room for the bends to get there. Maybe I can get something drawn up this afternoon when it gets HOT outside and post it so you can see what a challenge it is.
