Lawnmower wheels replaced cheap!
Logged a LOT of hours with these on golf courses in my younger days- height of cut is around 2 1/2- 3". Definitely NOT for putting greens, they (or any type of rotary mower, for that matter) can't cut nearly close enough for that height of cut (generally around 1/8" for bentgrass greens, slightly higher on public courses). Reel type mowers are used for greens, tees, and fairways.
