Quantity 2 Part # TP-17532 OEM Part # ET17532 John Deere / 2500 Medium Duty Bedknife. Turf Pride Premium Bed Knives. Turf Pride Bed Knives are available in three thicknesses and are available to fit major brand greens mowers. Hardness: Rockwell C scale 48 – 49 Material: Spring type steel high carbon content, with chrome/nickel alloys. Polish finish. Thickness: 3mm Effective Cutting Heights: Turf Pride (thin bed knife) 0.100 Turf Pride (super thin bed knife) 0.075 Turf Pride (tournament bed knife) 0.050 Straightness: In order to achieve maximum cutting performance, a bed knife must be perfectly straight. Even the slightest bow will result in less than desired performance. A bed knife with a “smile” shape will cut on each end and not along the middle. On the other hand, a bed knife with a “frown” will cut along the middle and not on each end. Turf Pride bed knives are guaranteed to be perfectly straight without the need of grinding after attaching. Thickness: With the Turf Pride premium knives, the over all thickness from one end to the other is guaranteed not to vary more than .001”. In low cut settings even the slightness difference in thickness will result in a deviation in cutting heights and will be more amplified the lower the cut. Turf Pride Premium bed knives will ensure a true golf ball roll on all putting surfaces. Hardness: Consistency of hardness is crucial in order to maintain an even and straight wear pattern. This again is critical when mowing at lower heights. Updated December, 2012. We are now making a 30 – 40 degree Manufactured Relief standard on all of our bedknives. No need to spend time grinding relief, saving dollars. Set grinding stone at 2 to 3 degrees negative. Then make 2 or 3 passes to establish the "land area" and you're done. Makes mid-season touch up a breeze. Manufactured Relief is exclusive to TurfPride. Payment can be made over the phone via Visa, MasterCard, American Express or Discover by calling 239-357-1853 Craig.
