I have a GC2400 with the FEL and the 54" 2320 mower deck. Yesterday I was surprised to see the front left gauge or caster wheel was gone...just the bracket that attaches to the deck was there. I've never had a wheel fall off any of the 3 tractors used for mowing, so I spent an hour or more walking around the farm where I had driven the tractor, mostly hauling logs and rarely mowing, but to no avail. I have no idea how this could come off, and not be noticed as I would surely have driven over it when it happened. This morning I thought I better see what the replacement cost would be. On my 2 tractors with Woods mowers, I expected them to be high, and replacing the wheels on one of those a year ago set me back around $70, each. Imagine my shock when I looked up the cost to replace this one small wheel assembly...$350!! Holy smokes! Is there an alternative out there. I was literally blown away.
