Mine is a old ford N series 5 foot 6 inch wide set.. 22 inch disks double gang .. if i don't hang 5, 42 lb weights off the front it will lift the front of my 2210.. With that four foot set you will be fine..
My 2210 has a full set of the suit case weights that came on it when I bought the tractor; now, if I just had a fall deer food plot to use it on... Maybe I need to rent myself out; I actually like doing this stuff so much, I would just about do it for free! Mind you, I am new to all this tractor/disking/cutting stuff. But it sure is fun!
Perfect match for your 2210. I have a frontier 4 foot disc harrow I use with my 2305. I do hire my work out. It can be very rewarding especially in the spring. I have done some deer plots for different folks. I have a 4 foot bushogg also along with JD 647 tiller,FEl,62" mmm, 4 foot BB.
