Used my old Dearborn two bottom plow for first time today.

[mike35549]

I got an old Dearborn two bottom plow few days ago. Well today i plowed about an acre with it with my Mahindra 2538 worked best as fast as it would go in low gear nit sure how many mph that is. Everything went a lot better than i thought it would after reading as much as I could about using one on here. It pulled straight, after a few adjustments I got it to where it was plowing pretty good. The only problem I had was that the front plow was plowing deeper than the rear plow. Front was plowing 7-8 inches deep and the rear was plowing 6-7 inches deep. Not sure why everything was level with wheels in furrow. I guess I could have made it unlevel towards the rear plow and maybe got them even but it was plowing good so I just went with it.

Keep experimenting with Three Point Hitch adjustments. Chances are you need to raise front plow a fraction, using the right lifting rod adjustment.

I use a 8" Torpedo Level to fine adjust the plows level front to rear and side to side. More efficient than making adjustments by eye.

Once rust is worn off moldboards symmetrically you will have to readjust.

Also, check to be sure wear parts are about equally worn on both front and rear plows.

Some grease plows between uses. If you decide to grease, use relatively waterproof marine grease.

I prefer one coat of Rustoleum spray paint, whatever type is around. (except pink)

If the shares are cutting level side to side slightly extend the top link till the share cuts are level Front to back.

You can block up the left rear tire the depth of desired furrow and make adjustments then.

He is in the ground now. He needs to make his fine adjustments with the plow working in his particular soil and particular moisture.

You need to block both wheels on one side in order to make approximate plow adjustments. Having tried that, not my favorite thing. With my plow mounted, the combination is three tons on little 6" X 6" X 12" blocks, which want to slide. No thanks.

Block size should not be a factor. You just use bigger ones if required.
Front axle is on a center swivel.

I keep a pair of 6" X 6" X 12 ft long timbers for setting up the plow along with other things.

I find it so much easier and safter to use a 8" Torpedo Level to fine adjust the plows level front to rear and side to side in the ground, relative to blocks. And, at age 69 years, I cannot manhandle a 6" X 6" X 12' piece of lumber.

Front axle is on a center swivel.

The front is still effected though, even though it swivels.

I use 8" concrete blocks. An 8" block under a single front tire most certainly will raise the front of the tractor. IT dont do anything about the side to side angle, but pitching the nose of the tractor up does have an effect on how you need to set the plow.

But just using a block under a rear gets pretty close. And then fine tune in the field.

Just screw together 4, 2x10's at the length you need for front and back tires, and angle the front cut at 45 degrees instead of using a 6x6. Can just use some cutoffs for each tire. Much safer and wider. You can add/subtract with a 1x10 depending on what depth you need based on your plow size.

I don't understand all the block talk?

If the front plow is deeper than you like, extend the top link. If you can't get the plow to engage, you went too far.

If the plow is operating in a manner that suits you then go with it. I've never measured with a ruler, the plowing depth. I just look at the finished product to make adjustments.
