I use my Gator on a farm in fields. When it is in 4 wheel drive it works fine going forward. If I stop and put it in reverse, it seems like it is bound up, and when you back up it seems like the front wheel kinda drag and aren't going the same speed as the rear ones. You can see where the left front wheel kinda tears up the grass when backing up. It is really hard to turn when going backwards. I then stop take it out of 4wd, and go forward a few feet and then I can back up with no binding. It has 200 hours, and I'm just a old guy who putts around the farm fixing fences, and cutting wood. It is the gas model. It has done this for a long time. I only use the 4wd when going through wet areas, and take it out as soon as it is safe. Of course the dealer went out of business the day after I bought it, and its a long ways to the next one.
