Was wondering if any tractor gurus could help me out ... will be mainly mowing approx 4 acres of flat land, 2 acres will be "lawn" the balance mainly thicker "thatch" .. I'm down to a 21D or a 4100, specs appear pretty close ..21 vs 20hp, 16 vs 17pto, but the thing I noticed was the total pump flow is 7.4gpm on the 4100 vs 6.75on the 21D but the Boomer has a lift capacity of 1265 vs 930 on the Deere ... since I'm thinking I'll get a belly mower, post hole digger, and a blade at first to do some landscaping , then throw a FEL on later ... is there something I'm missing here? Any comments on either of these two tractors would be greatly appreciated !!
