Hi,
i looked at everything there and since we were (believe it or not) actually downsizing from a bigger tractor, I ended up at the 1433 with a bunch of nice accessories. The bigger tractor (a nice cab Deere) couldn't get where we wanted to go, and ate up the lawn. Most of our tractor stuff is light loader (1,000lbs max), tilling small areas, light drive grading and pasture mowing. The smaller tractor will fit the bill nicely. Sounds like you need a bigger beast! Haying all that acreage would be a chore on a CUT... We have two bobcat mowers for the lawn, so no MMM needed. worked out great. Those people were awesome, I can't recommend them enough. Go see Wally and the boys!!! (My new tractor arrives Monday or Tuesday, signed today, pretty fast!)
