Hi Mowerfreak thanks for that mate, I have a couple of vice grips in the toolbox when I get around to it i'll see how straight I can get them. Yes your right they will be far better than what they are now. I had to actually push it around with the front wheels off the ground as to not scrub them out badly, and also it was hard to push as they are pointing outwards a fair bit.
One thing I have noticed though with these older thick rubber wheels on this mower when compared to the other powertorque style wheels is how smooth and quiet these older thick rubber wheels are when pushing the mower around on the road/footpath when compared to the other harsher hard plastic tread powertorque wheels, which sounds and feels like you are pushing the mower around on steel bearings when compared to the earlier thick rubber wheels! lol
Cheers!
