I was told about a set with good tires. Never seen any on an N series so I am not sure if that is what they really for. We ran a Massy 1085 for years, mainly hay. We also used what I am calling a batwing disc at times. We never had any problems but would hit them with an impact every so often. My tractor really does not work hard unless I am pushing dirt around with the dozer blade. It is more or less a mobile power source to run the backhoe, so I have no need for a seasonal width change. If I get these wheels does the group recomend swapping the tires over to my existing rims? Assuming the tires are in good shape I wouldn't need the wheels any longer than what it takes to clean up my existing rims. Going to offer $150 for the pair and see where it goes.
