Well, I chose. 5075E arriving next week. Unfortunately I couldn't find what I wanted in the used market for anything but a pretty small discount to new, so I went with a new machine.
Reasons I chose this over a 4720/4066:
- Larger frame and heavier....I'm hoping this, plus filled tires, and moving wheels out as wide as they'll go, will make for a more stable platform than wide+filled wheels on a 4-series (though maybe each properly configured would be equivalent)
- Clearance: 5 series has more clearance than 4, steering components on the 4 are pretty low. I'll be beating this thing up in my rocky woods.
- Cat 2 vs Cat 1 hitch. I'm gonna use a backhoe attachment occasionally; the stronger hitch and mounting hardware gives me the option to do this in 3pt variety (ie, without installing a backhoe subframe...which I might do anyway, but dealer assures me it'll be fine on the 3pt)
- More power (and traction) for hauling logs out of the woods uphill.
- Ultimately just more operational options with the bigger machine. I realized the 4-series is probably too big for around my house/barns anyways, so may as well go a level up since work in narrower spaces is ruled out for me to begin with. So more power for fields and woods.
Anyway, we'll see. Maybe in a year or two I'll wish I had the smaller tractor, but I suspect if I'm not happy with the 5075E, my conclusion will be that I should go more specialized and buy a skid-steer & and a mini-ex or something. Seems some people start with a utility tractor and end up with that conclusion. We'll see - looking forward to the tractor right now though.
