9.7 BEDKNIFE-TO-REEL TRUESET™ REEL ___________________________________
(Pre-adjustment Check)
1. Check the reel bearings for end play or radial play. There should be no end play or radial play. See Section
4.9.
2. Inspect the reel blades and bedknife to insure good sharp edges without bends or nicks.
a. The leading edge of the reel blades must be sharp, free of burrs and show no signs of rounding off.
b. The bedknife and bedknife backing must be securely tightened. The bedknife must be straight and sharp.
c. A flat surface of at least 1/32 in. (0.8 mm) minimum must be maintained on the front face of the bedknife.
Use a standard flat file to dress the bedknife.
3. If wear or damage is beyond the point where the reel or bedknife can be corrected by the lapping process,
they must be reground.
4. Proper reel-to-bedknife adjustment is critical. A gap of 0.001 to 0.003” (0.025 to 0.076 mm) must be
maintained across the entire length of the reel and bedknife.
5. The reel must be parallel to the bedknife. An improperly adjusted reel will lose its sharp edges prematurely
and may result in serious damage to the reel and bedknife.
6. Grass conditions will also affect the adjustment.
a. Dry, sparse conditions will require a wider gap to prevent heat buildup and damage to the reel and bed -
knife.
b. High quality grass with a good moisture content requires a closer gap (near zero).

CAUTION
To prevent personal injury and damage to the cutting
edges, wear gloves and handle the reel and bedknife
with extreme care.
