Brinly Hitch Adapter Plans
 

I want to build a Brinly-type hitch adapter for my narrow frame Cubs. I found design plans from Steve Spencer on the hitch and receive the lift strap dimensions from Charlie Proctor. I question Steve’s dimension for the width as he has 9.50 – using .38 inch steel that would mean that the lower hitch bracket on the tractor itself would have to be smaller than 8.75 – I measured mine at around 9.06 to 9.10. I made a drawing using some of Steve’s design (okay, most of Steve’s design) and Charlie’s lift strap measurements. I changed the 9.50 dimension from Steve’s to 9.88 (I’m thinking about increasing this also).

Unfortunately my design plan is in the pdf format and is 111KB, so I can’t attach them here (too big). I want to get some feedback, and this might benefit anyone else who wants to build one. So……

nicely done I was going to build one for my 782, is it nescisary to have the inside mount on the rear diff cover where the the pivot mounts to? i guess i could see it being a better stonger set up than just the single hole org factory set up

No, but it's a good idea. The double bracket lets you use clevis pins to attach the sleeve hitch adapter to the 3-point without destroying the holes in the lower 3-point bracket and adapter. With the single lower bracket, I'd advise using a rod all the way through both sides, and not using clevis pins, as the pins will cause wear in the hitch and adapter if it is just a single bracket.

Here is will happen to youe sleeve hitch adapter if you don't use a double yoke:

The shiney area was welded to build egg shape hole back up. The holes had that much wear in them from a single yoke system. Aother problem with a single yoke set up is you will have side play in you implement.

I did some research awhile back in the Cub Cadet parts lookup. The IH tiller, box blade and rear blade had support on both sides of the implement's arm. IH engineers saw the problem and had a solution for their products. I'm not a big fan of using a a rod all the way through both sides as Matt suggested. The rod can and will bend.

This is the set up I use:

gotta wait a while but ill be getting on that project after my 106 rehab... should be a fun little project.

The doubling of the lower hitch gives me an idea - tomorrow I will try and put a Rev "A" to my plans to include an extra "arm" on both sides to mimick what Merk has shown. Only it will bring the doubling effect to the hitch adapter, not to the tractor side.

There may be a couple of ways around the problem. One is as Matt says, is to run a rod through to both sides and then encase that in a pipe to prevent bending. Or, use bushings in the yoke of the hitch adapter to spread out the load and to give it a bearing surface. Thirdly, double of the yokes on the hitch adapter to mimic Merk's picture (only the doubling will be on the hitch adapter only). Lastly, follow Merk's picture. I will see what I can come up with.

THAT shound be just about the same but just doubled in another area, and i just put a new gasket and fresh hytran in there, so not wanting to break thoses bolts loose

Based on Merk's comments and based on more info, I made a revision to the design. Comments or suggestions appreciated, thanks.

The double arm is a good way to go if you only have a sleeve hitch adapter. I have at least 3 different attachments that will need a double arm. I would add a cross brace to lift tab (#6). My sleeve hitch adapter is bent in that area.
