 Topic: Plow adjustment
Posted: 24 May 2017 at 10:26am |
Soooooo......Our farm owns or has owned at one time or another 4 semi mounted plows including the "new" Deere 2810 which is really a whole 'nother animal. We had a Allis 2000 series which I don't have anymore. We have an ancient Deere, no clue what the model is, decal was long gone when we got it 30 years ago. Now have this Ford which I think is from the early '80, some say a model 132, not completely verified. I have never had a book for any of them except the 2810, and again, that thing is quite different. Attached are pictures of the Deere and the Ford. Both have a link that goes from the hitch to the plow frame. I "assume" (yeah, I know) the Allis had the same type thing. What does adjusting that link do and why?

Its just added support for the hitch. It looks like the Deere hitch can be slid side to side which would change the length of the rod. The adjustment takes up the slack.

Agree, just a brace to help support the hitch when pulling.

Well, that's what I originally thought too. But especially on the ford, it is "enormously" adjustable, probably 6 inches or more, holes spaced every 1/2 inch. Seems a very odd way to build a brace. I changed it on the ford last night, and it changes the angle of the hitch mast to the rest of the plow, not necessarily a good thing. I was hoping it would change the pitch of the plow pull to the right, but I don't think it will do that. I didn't get a chance to pull it after the change last night, rained out. The JD one will adjust a lot too, but not as much.

By the way, both the Deere and Ford hitch does indeed slide side to side, but has no effect on the length of this rod. It's done by moving the "tow bar" through the front part of the hitch that clamps it in place. On the Deere, it's like moving a front axel in / out with spaced bolt holes, the Ford you just loosen up and slide wherever you want it.

If you move the hitch up or down you would adjust the rod. side to side wouldn't require you to do anything with the rod.

danraley, that makes sense. Move the hitch up or down, and you'd want the mast to remain relatively vertical. So....how would you adjust the trailing pitch? Doesn't seem there would be a way, since the hitch can pivot like a pintle, it's just going to trail like it wants to.....On the Ford plow, the tow bar is made with an offset. When I got the plow the offset was in the "vertical" plane. If I rolled the tow bar 90 degrees, it would put the offset in the horizontal plane, which would change the pitch of the hitch, but the plow frame itself would be free to trail however it wanted to steer itself by the bottoms.

I looked things over some last night. I didn't have a ton of time because I had to grind feed. The hitch mast on the Ford can indeed be mounted to the main frame in 3 different vertical positions and 3 different horizontal positions, as well as the tow bar itself can be slid from side to side quite a distance. Changing where the hitch is mounted to the frame in all those combinations would require adjustment to that link in question to keep the plane of the mast nearly vertical, though I'm not sure as much adjustment as they built in! Wow, I should have counted holes, there's a bunch! On the Deere plow, the mast can be mounted to the main frame in several vertical positions, maybe 4? There is no side to side mount there, just the tow bar itself, hence not as much adjustment in that link. Kinda makes sense, in fact I just undid my change last night to the Ford without trying it based on this discussion. So, the question is, is there a way to change the trailing pitch of a semi mount plow? The only one I can think of is to adjust the steerage of the tail wheel, but I believe the draft forces are already way overcoming the steerage of the tail wheel and pulling the plow left. I'm in sod. The plow pulls off to the left so bad, it's acting like a ripper. There's 4 slices in the ground, and all completely green side up, no turn over at all!

Dave, I think that's part of the problem. They are there, but quite worn. Been on order for almost a month.
I think there is enough there to do OK until the new ones are here, but maybe not.

Well, the Ford is not a model 132, like some thought. I ordered a manual for a Ford 132, and in the manual it says 132's were made in 5, 6, and 7 bottoms. This is a 4, so not a 132. It looks extremely similarly built though, so even though some of the dimensions may not be correct, hopefully some of the concepts will help me figure out this plow's adjustments. Manual shows a 7 bottom being pulled by 130 HP. GRRRRRRRRRRRRRRRRR!!!!!

Hmmm - maybe you could post pictures that show all of both plows from various angles so guys on here can maybe ID the model numbers?

Dave, I did that a while back, post title "Off color Plow" or something or other. I thought about posting this message on that one, but .. . .it's way back there somewhere and search function was arguing with me about permission.
