A spin grind only reel means the reel has to be reground as soon as quality of cut has declined. I notice that spin ground reels get dull rapidly when cutting bermuda, seashore paspalum or zoysia lawns. Lawn services with reel mowers sharpened that way get less than a month out of their machines before they start tearing grass or jamming. A zero contact spin ground mower might be ok for bent grass on a putting green, most lawns are not bent and they are not cut every day.
hhmmmm maybe that explains why my mower got dull so quick after i had a golf course sharpen it for 50 bucks. i know if i take it to the REEL mechanics they charge 110 bucks but i think the take the whol mower apart and all and backlap it.

spin grinding is where they put some type of grit on the blades right?
