My question is what gear or ground is ideal for chissel plowing? I'm planning on going about 10 to 12 inches deep. Any input or opinions is appreciated Thanks smalltimer [Reply]   [No Email]

The plow just has 2 or 3 inch straight points and the tractor is dualed with a full set of weights up front. Tried it a bit today and probably going to drop the outside shanks off in the future. I could only run about 7 inches deep and was running in B1 most of the time a little in B2. Pulled a couple wheelies. This ground hasn't been worked very deep for the past 10 years or so. Had a friend working another field with his Titan four wheel drive with 500+ horse with a dmi ripper and could only go about 8 to 10 inches deep previous tenants didn't believe in working ground very deep it was to rough for them in the spring they always said.

A chisel plow needs to be pulled "Briskly" to do a good job, if you are fighting for traction you lose the turbulence of the soil flow, and end up just "scratching". If you plan to farm with a tillage method and a mid to small tractor you would be much better off moleboard plowing...you will end up with a more consistent seed bed. [Reply]  [No Email]

I used to pull a 11 shank with 4 inch twisted teeth with a turned up 4640 (200 hp) and dual 20.8-38's at 10 inches deep and 5-6 mph and it was plenty enough for that tractor in average conditions here with our mixed soils and a few stones.

Pulled it in B2. [Reply]  [No Email]

Currently in the market for a good 4630 to pull the 7 shank Glencoe. In my opinion, anything bigger than that will be too much for a 4630. That is here in Illinois so it cold be different in lighter soils. We used to pull an 11 shank Glencoe SS with an IH 4586 4wd 300hp. [Reply]  [No Email]

We pulled a 14 shank case chisel with our hot 4440 for a few years. It had plenty of power, but hard to keep the front down. Most of the 44 and 46s around here pulled 10 shank chisels.
