Dearborn 10-80 instructions for use/tips

Hi,

I recently test drove my (new) Dearborn 10-80 on a friends field. I recently acquired it, replaced the shot bearings and the worn discs.

He wants to flip over about 1 acre of sod and plant a cover crop on top while the sod slowly decomposes, so he can plant crops next year.

The 10-80 printed instructions make it sound like any moldboard plow. I leveled it side to side and fore and aft, and connected it to the bottom hole of the top link.

It made some nice cuts for a short distance, but then tended to pull up and out. It never cut more than about 4-5" deep, which seems shallow.

It has the massive cast-iron weight its supposed to.

Suggestions? Plow speed? Position control? (this tractor only has draft, and is also new to me).

thanks in advance.

Bill
 
What length is your top link set at? most of the old Dearborn plows were made to use with the top link set at 25". When you said it wanted to pop up and out is it just jumping up or is it going to the left and coming out? If it is going to the left and pulling out then it is the furrow wheel causing the problem. If the furrow wheel is right and the top link is set correctly, other than leveling it once your in the furrow, they run easily. Draft is what you want for that plow, not position control. The cross shaft hasn't been moved has it?
 
I will check the top link measurement. I ahd it leveled fore and aft.

The furrow wheel may not be working quite right as it does tend to steer the tractor a little to the right. I wonder about the spring ont eh furrow wheel- might it have gotten a little lazy?

the soil wasn;t the easiest - old sod athat was maybe still a little damp.
 
Thats the thing about disc plows, they don't care if the soil is damp or hard as a rock they will plow it. If the disc on the furrow wheel is worn down it will tend to come out of the furrow. The furrow wheel is the key to getting a disc plow to work properly.It may be the spring is weak, but I can't say for sure. I have never used a Dearborn disc plow, all I have used is the Ferguson disc plow that I have and even though the operation is the same they are quite differently built plows.
 
I said something about draft control which is what you want for plowing but the draft control must be adjusted and working properly. Not saying yours isn't but if it wasn't it would make plowing with one much more difficult.
 
I am going to swap tractors for one with a better-known working draft control.

Furrow wheel looks fine to me. I can send pics. I will also check the cross shaft.
