I've noticed that some of the wider fixed deck mowers have quite a spread between the caster wheels, and since they don't have anti-scalp rollers, you could get some nasty scalping in the middle. I suppose I could try to buy some anti-scalp wheel assemblies and have them welded to the deck, but even anti-scalp wheels can do some damage when you're turning into a rise, and they're not as easy to adjust height on. So, has anyone tried or thought of adding a 3rd center caster wheel assembly to the middle of the deck to handle terrain better? It could just bolt on rather than require welding and the technical problems of that. And since the wheel casters, the mounting arm wouldn't need to be mounted straight ahead, like the anti-scalp wheels would. Is there some technical problem with this I'm not considering?
