When we purchased our "new" home back in October, it came equipped with an older Husqvarna lawn tractor. Probably one of the most user UN-friendly units I've ever owned, but in general, does the job. Unfortunately, I believe the tires on this thing are the originals (unit has just under 800 hours on it) and one is constantly losing air and both are weather-checked. I'd like to replace both, but can't get the wheels off. I can't because, there are wheel weights on both wheels and I can't get those off, which needs to happen if I'm going to get at the wheel lugs. They're some type of plastic/poly, and I believe, are probably sand-filled or such. They bolt on with two through-bolts on to the wheel. Loosening the bolts is a piece of cake, but I swear these things are virtually *welded* on to the wheels themselves. I spent close to two hours on one side Friday, trying to get the thing off. Beat on it, tried prying, squirting WD-40 back behind it and beating on the back side with a drift pin. A lot of sweat and banged up knuckles later, still no luck! Any ideas? I'm almost at the point of taking my reciprocating saw to the stupid things and having to destroy them, in order to remove the darn things!
