    Default Re: What size HP for a 3 furrow land plow

    I run a 3 furrow plough behind my MX5100 (50hp). The soil however is a decent loamy type with some clay lower down.

    If it were me, I would buy a 3 bottom for decoration, maybe plant some flowers around it then go by a chisel plow and call it a day

    You can remove the rear bottom if you can't pull it as a three. What tractor do you have?
    I have a Branson 47 hp.
    Seems the area is a lot of clay according to the well drilling chart

    47 engine or PTO? PTO horsepower is said to roughly translate to draw bar horsepower. Your power might be marginal for 3x16 but I pulled a 2x14 with a 25 PTO hp tractor and it did well.
    That's the picture in my signature.
