if you scroll down on the page you will see the gator utility vehicles. we had a bunch of them at the golfcourse i did greenskeeping at in high school. we had the 6x4 and the 4x2 type. all you would need is 4x2. these things were practically indestructable, we tried ;f, and with a little common sense, we were 17 and had little, you will never get stuck. great little machines.
to avoid sticker shock you might check with some of the local golf courses to see if they are looking to get rid of one. they are easy to fix and maintain and last a long long time. there was a 3 wheel gator there that was 15 years old. not the best machine but it got the job done.
