at sunflower we've been using a 2WD Gator for quite a while. It's handy for pulling a sprayer, brushing off the runway (with appropriate attachement), and we use it to tow gliders on our concrete ramp. The only complaint we have is that we have trouble holding a smooth walking pace. Ours seems happiest just a little faster. We've actually been talking about getting an electric golf cart to try out for towing out.
