I need a 3 point hitch geometry lesson.

You mentioned in an earlier post that you wanted 1000 lbs counter weight. Are you sure you can lift 1000 lbs on your 3pt. For ref, a 55 gal drum of water weighs in at 440 lbs. What do you think will happen to the front end with nothing in the FEL. Your pivot point is on the front axle/wheels, and any weight behind that is counter weight. I believe I would try water in a barrel first and find the right combination of filled tires and additional weight needed. An empty barrel is easier to handle.

Please refer to post #19.

Thanks! The CAT 1 dimensions should be close to the same. Ideally you should have the top and bottom pivot points parallel but this is not possible with the barrel set up. Would you be somewhere close to 2 or 3 inches away from the edge of the barrel on your top pivot point? Is the distance between pivot points around 16 inches? Another question I have would be what is the distance you put the bottom bar from the front and bottom of the barrel? I hate to be a pest but if you built a good working unit then why not share?

I would like to add a drawing but I'm not sure how on this site

One way to add a drawing is to save it in one of the extensions that TractorByNet recognizes. On the page you post, lower half of page,you will see manage attachments, and select it. Under the attachment list is all the extensions that can be used and the max file size

I see, said the blind man. Must have skipped that one

Attached is a drawing with dimensions I think should work. Anyone on this site care to comment?

For cat 1, I would go 24" instead of 16 from top link to bottom. This measurement is off my 48" woods rm mower. I don't have a fel and have no need of a counterweight but I would recommend running square tubing out the rear for a hitch for added use. Dad did that 30+ years ago on a IH 3616 TLB that the backhoe was removed from.

Will you be using a stationary top link or hydraulic? Stationary top links and hyd top links are made in various dimensions with some adjustments. The height of the implement will dictate the length of the top link.

If he measures his tractor's pivot points it will give him his approximate measurements. With the top link it can be spun out a couple of inches to allow for how much adjustment you want, when you build the frame, put the drawbar in the lower mounts and you will see when the top link is paralell, where the mounting point should be. This is the simplest way to gather dimensions. Also the reciever tubing added to the frame is a great idea.
