I am using a 2004 Honda Rubicon 500cc with electronic shift. It has the solid rear end. I removed the original hitch and replaced it with a 1/2 inch plate U-bolted to the axle tubes and a brace downwards to the rear end housing so the hitch wouldn't drop. I did this so the rear end housing wouldn't breakup as it is only aluminum. I then built an A-frame that couples to the hitch with a drop in bolt. At the front are two uprights welded to the A-frame. These bolt to a cross bar which is U-bolted to the front brush guard. I built a 4 foot wide by approximate 20 inch high dozer blade of 1/8th. metal, curved and re-enforced. A 3/4 inch "T" rod fastens the blade to the A-frame and has a spring clip for easy removal. I use the winch for raising and lowering the blade. This quad came with a full time 4x4 with hi and low range. I modified it by putting in a Detroit Gearless Locker in the front and and a 4-2-4 front drive shaft from Hi Lifter. This drive shaft is engaged and disengaged using a heavy cable much like the older grain or gravel trucks used to engage or disengage the power take off. For normal use, one does not need the quad in 4 wheel drive, and being out of 4 wheel drive the turning radius is greatly reduced. For good traction I use MudBug or Bear Claw tires which have a deep tread. For travel in deep snow, I remove all 4 wheels and install a track system where each wheel was fastened. To use the track system the quad has to be operated in 4x4. This quad was purchased new, is well looked after, not driven at high speeds, nor used in quad derbies. It has given me excellent service and has approximate 1500 kilometers on it (just under 1000 miles). At times I do a lot of heavy pulling and by having a quad that is not belt driven, I am able to gear down and still keep my engine rpms up for maximum horsepower. At that time 500cc. was the minumum recommended for running a track system and at that time the track system was relatively new and was not recommended for independent suspension. Since, several companies have come on line building track systems of different designs making for easier steering and narrower front system so one can drive between the fender wells of a full size pickup. Mine being the older design, is either hauled on a trailer or loaded on a ramp system that is level with the top of the pickup fenders, putting the quad much higher when loaded.
