FMC Sidewinder brand, model SW66, rotary mower. Pull type with pin hitch and adjustable height side wheels, especially handy for the pulling tractors like Farmall, Allis, Deere, etc. Replacement tires just added. With the heavy duty drive wheel than can be adjusted with shims and then reversed to the other side of the drive tire for many more years of use. I use a similar 7’ sidewinder mower and it works great. $460.
