We currently have a Gator 4x2 (gas) that we use to run up and down our 1/2 mile gravel driveway to take out the trash, pick up mail, etc. Parts of the drive are very steep and the Gator is painfully slow to climb hills, and with no rear suspension and no front brakes it can be hairy coming down the hill. We're considering upgrading to something a little more capable, but can't afford a new one. We already have diesel on site for the tractors so we want to go with a diesel Gator to eliminate the need to store gasoline. It must have front brakes and suspension on all wheels. 4x4 would be a plus but is not a requirement. I'm finding HPX 4x4 diesel and an XUV 850D. What is the difference between these two models? It looks like the HPX has a straight axle and the XUV has independent rear, is that the only difference? Are there any others that I should be searching for? What is the top speed on these, and do they climb hills without slowing to a crawl like the 4x2?
Thanks in advance for any input.
