I am going to buy a 4 wheeler to spray lawns with. The only one I can find that has the "Turf Mode" is a Polaris sportsman x2 500 or 550 or 800. Question is does any other brand of atv's make a turf mode so I can turn sharp corners without ripping up customers turf. Maybe an aftermarket rear diff. that will unlock the back tires so only one spins at a time? I don't need such a large 4 wheeler with all the storage and second seat. Too many options on the Polaris for me. Just want a smaller basic setup.
