Roger that, I was not certain. *and I was too lazy to price check*
Your message prompted me to call Gene at Get Sno.
That wheel which is for a wide track steel cleat machine is $654.00 loaded, which means it has seals and bearings.
Apparently it is an Extra heavy duty Ice Breaker. according to Get-Sno it was available on the wide tracks or by special order.
Spindle was surprising cheap, about $100
So like the add says less than $600.
