Yamaha Grizzly or Polaris Ranger...
Kawasaki Mule tends to be a cheaper but adequate utility vehicle.
I use a Kubota B8200 compact tractor, it's small but has a class 1 rear lift and PTO and adequately replaced an old Fergie tractor (it's also very narrow and has optional 4x4 and lots of gear options).
I replaced an old 1 tonne 2wd single cylinder dumper with a much heavier 3 tonne 4x4 electric start articulated steer dumper, but it is much bigger, wider and higher in woodland (risk of head / eye injury from low branches with no cab), it isn't that practical for lots of woodland use loaded in the wet - although it will go almost anywhere it can fit, it will make a mess.
There was an advert locally for horse-logging, which isn't such a bad idea narrow with multi-tool frames
