sunnyside, yes I did install them myself. Its just a matter of taking your wheels and tires off the tractor hubs, then bolting on the extensions using the bolts provided. Then once the extensions are in place, bolting the wheels onto the extensions with your factory wheel bolts. The trick since you have loaded tires is going to be to get the tractor at just the right height so you can place the wheel hubs just right, so you will not have to lift the loaded tires and wheels to get them lined up and bolted to the extensions. Get some help if possible the loaded tires are going to be too much for one person to handle. It would be nice if you had a neighbor with a tractor/loader to help. I had no trouble doing mine myself,but my tires are not loaded.
Sincerely,
Dirt
