3 pt arms

Ted in NE-OH · Nov 12, 2019

I need to make some custom 3 point arms, I know it is made of tough steek and probably heat treated. What steel are they made of?

I mean "steel"

I made some for a Allis WD 45. From the snap coupler of a 3 bottom AC plow. Everything is there. Almost! Have lasted 30 yrs.

Depends on the size and lift of the tractor. No special steel is needed til they start lifting a lot.

I'd be looking for some factory arms as close to what I wanted then modify them.

Factory arms might be heat treated but you'll never be able to replicate it, so just use mild steel and err to the side of overkill. At least as thick and wide as the end of the ball that you weld to the arm.

The benefit of mild steel is that it will bend and not snap like some homebrew attempt at heat treated steel.

I recently bought some from TSC and cut them and modified them to fit my Kubota L5030.
They were not expensive.
Tractor did not have them when I bought it.
It was used pulling an irrigation trailer on golf courses when they put in irrigation lines.
I cut the arms I bought and welded them up with 7018 AC rods.
Was easy to do.
Got stabilizer bars to put on now.
Also modified the old yellow links that pick them up.
They had been in my barn forever.

They are probably made from C1010-1018 cold rolled steel. Nothing special.

How much sway in that setup? I need to fix my Ih454 cause all the adjustments are rusted and won't turn. That looks like easy fix for mine.

Orignal bars on the Grey Ford and Ferguson tractors were easy to bend and straighten.
