Newbie needs help. I have a 26 horse Mahinda. I am looking at plows for a 1 acre food plot. Would a 1 bottom plow be enough or would a chisel plow be better. Ground is soft loam with grass/weeds now. Can't figure out what a chisel plow might be used for.
All those old n series Fords would pull a single 16" (Or 2X12") plow with less HP than you have at your disposal. Not sure of the model you have, but some compacts just don't hitch up well with a lot of CAT I plows. I believe it's Lienbach that sells a plow for "limited CAT I" hitch's. Weight/traction might be your limiting factor on how much plow you can drag.
A moldboard plow will do what you're trying. A single 16" pulled @ 4mph will cover just over .6 acre in an hour of plowing.
A chisel plow is the best method of tillage in MOST soils, IF you plan on deep tilling. The problem is, a REAL chisel plow will take a bunch more HP than you have for one of any width. At "normal operating depth" for a chisel plow, you'd be lucky to move one shank. Chisels are intended to operate 8" (at minimum) to 12" or 14", all dependent on current soil structure and its needs. (You'll find people that refer to their field cultivator as a chisel plow. There is a difference. Not made to work as deep)
The best alternative to chiseling with a small tractor is a subsoiler. One shank that can be pulled at whatever depth you so desire.
The object is to break up surface soil to a depth BELOW compaction level. If this ground has been previously worked with a moldboard plow, or just "pastured", it will have a compaction layer AT LEAST 8" to 10" down. NO moldboard plow will dig down that deep and UN-DO that layer. That's where chisel plows shine. In fact, a moldboard plow can actually make the "plow pan" (layer of compaction) worse.
I'd suggest plowing ONE TIME to deal with the sod layer. After that, look to use ONLY a disc or tiller in subsequent years. NATURE, with her freeze/thaw cycles will do what the cold steel of a plow can't.
