Re: Is my tractor big enough for a 3 botto plow?
I'm not sure how big your 3 bottom plow is but plowing speed is an important factor. It's alot better to plow fast, it will turn over faster and break and you will get better coverage too.
I've been pulling two 14s with a Ford 2000, probably aroud 35 HP, for 32 years. It does a good job but wet spots and uphills are a challange, sometimes I have to go down to 1st gear and I have to play with the depth alot. This year a bought a 5010 Mahindra, 5O HP, about the same as your Massey. I can go much faster, never have to gear down or fiddle with the depth. I think it could pull a third plow but it does a great job with the two 14s and I wonder if there would be anything gained. Maybe two 16s would be best.
Not a direct answer but I hope it helps.
