I'm shopping for a 6' - 7' disc harrow for my new Kubota GL3940. I'll be using the disc for about 5 - 10 acres of food plots, with most of the plost in the 1/2 acre size. Money is definitely an issue, but I don't want to go cheap and be sorry later. Any recommendations on make and model?
Are these food plot areas covered with turf or have they been tilled recently?
If the soil is virgin turf, I would expect that you would need a heavy offset disc to cut through the turf. Otherwise, you might be able to get away with less aggressive tilling using a tandem disc.
IRRc, food plots generally don't require deep tilling (6" or less). Once you get the turf removed or buried, your 3940 could handle a 6-7ft tandem disc.
My discs are all old, vintage stuff so, unless you're in the market for that kind of hardware, I can't give you a recommendation.
Here's my offset disc, a heavy old 1940s vintage 6.5 ft Towner loaded with about 400 lb of concrete weight to work in my dry, hard soil. It 's hinged on the right side (two pairs of axles in a V-configuration) and is considered a primary tillage implement.
This disc was a gift from a neighbor. Figure on adding weight to whatever disc you eventually buy to get it to work effectively.
My Massey Ferguson 6-ft tandem disc ($200), 1950s vintage. It's hinged in the middle (4 axles in an X-configuration) and is considered a secondary tillage implement.
My 1960s vintage Minneapolis Moline 13-ft tandem wheel disc ($600) has been cut down to about 10-ft so my Mahindra 5525 (54 hp engine, 45 hp pto) can handle it. This very heavy disc was actually built by Krause, a big name disc manufactured still in business. Your tractor needs remote hydraulics to operate something like this. Wheel discs, like 3pt discs, are nice to have when road transport is required.
Note that these are pull-type disc. I don't own a 3pt disc.
Don't know if this info helps you at all. Good luck.
