I used the Kubota for a couple seasons and it is a workhorse. Aux hydraulics are great and a lot of attachment options. Top speed was an issue but for a work rig 25 is usually enough. The bad about it was that the thing was very heavy and not overly rough terrain competent. E-brake can be a bit of a pain n the hydrostatic transmission will hold for a minute and then release when parked, if the brake is not tight it will roll. Ask me how I know

My FIL has gone a few thousand miles on a couple of the trail narrow Mules and loves them. He runs an off road motorcycle track and works the thing relentlessly. I have run them a lot and they are very solid and hard to get stuck. Not all the bells and whistles but tough machines.
I have a Gator for work and it has been pretty solid. Bought a cab heater and lighted it all around. Winch is next. A real pain to work on and the E-brake sucks!
Friend has the Ranger n loves it, much better than the Gator which he ran previously.
