    Default Building a "chisel plow" for CUT.

    OK, its really a small chisel plow. I am putting together a 3-POINT HITCH garden tillage tool from parts off an old field digger. It will be pulled by a jd4100, 20HP 4wd hydro. I think I can pull 7 tines thru the garden, expecting to take them to maybe a foot depth after a couple passes. Sound reasonable? these are the 2" wide tines (are they called danish tines?, can't remember). They are each spring loaded to the frame. I have all the materials now and will start this weekend, pictures then. If anybody has any feedback on the 7 tines, let me know. I was going to use 9 tines, but started to get nervous. I want to be able to pull it. I have turfs, btw. And can have the loader on for more weight. ThANKS.

    So is this like a 3 row cultivator?

    Brinly-hardy.com show a cultivator that uses 8 shanks and are typically used on 20hp garden tractors. Based on that, Id say that go with nine shanks.

    If you're talking a real chisel plow I doubt that a compact could pull one tine much less seven. A cultivator is much less aggressive and would be more suited to a compact. Here's a pretty serious chisel plow with some serious horsepower in front of it

    I have a B7500 with r4's and with my neighbors 4 tine chisel plow i will still spin out before 12". I would not go with more than 4 and put them at least 1 foot apart as a minimum. Also it would depend on soil type.

    Rule of Thumb for a real chisel plow is 1 shank per 10hp. But that is much deeper (there is a reason they are called subsoilers) than what Jim is going. I also think that Rule of Thumb starts at 40-50 hp, i.e., a 20 HP CUT won't have the grunt to pull one even if the rule says it can pull 2. At the 1' depth, that's a cultivator, not a chisel plow. No matter what the source of the teeth/tines/chisels. You might be able to pull all 9. I doubt it, but make the frame long enough to give a place to put them. If you can't pull it, a torch or sawzall will solve your oversized frame problem. I also expect soil conditions will have a large impact on your pulling ability.

    Sounds like a [img]/forums/images/graemlins/cool.gif[/img] project. Always neat to have the parts, and the ability to put them together into something useful.

    Jim do u have a box blade w/ rippers?
    If u do shorten top link and drop rippers down and try this.
    It will only go about 6" deep but will give u a feel for # and size of shanks.
    our chisel plows go 9-12" deep, use to break up hardpan below moldboard plowing
    sub soiler goes 12-24" deep, shatter and lift soil profile
    Field cultivator goes 2-4" deep, for leveling instead of discing
