I have been considering purchasing a John Deere 790 tractor with turf tires. I plan on equipping it with the 60" mid-mount mower and using it primarily for mowing the lawn. I also plan on purchasing a rototiller and possibly a box blade. Is this too big of tractor for mowing (about 2 arces of lawn) with and too small for rototilling (about 1 acre)? I think the 790 with the mid-mount mower is about $15,000. I don't know how much a PTO driven rototiller is. BTW, I plan on buying 3 more acres across the street and installing a soccer field (180'x330', about 1.5 acres) next year, so I will have a larger area to mow. Or would I be better off purchasing a large garden tractor for mowing, say a JD GX345 with 54" deck (about $8,500) and the rototiller attachment for my Bobcat (about $5,000)? I have a Bobcat 773 for loader work, so I don't plan on purchasing the loader attachment. I also have the 60" Brushcat for the Bobcat, so I don't need a rotary cutter for the tractor. Also, my business is currently more geared toward landscaping and land clearing right now. I don't plan on a mowing service other than just the first or second mowings on new lawns, but will do those with a walk behind mower. I might set my son (14 years old now) with a mowing business soon, but would be 2 years before he could drive and tow a trailer to a job with a riding mower.
