CUTTING DEPTH ADJUSTMENT
With the engine stopped and the reels raised, adjust
reels to desired cutting depth before using the mower.
Optimum cutting depth is 0.125 to 0.1875 in (3.2 to
4.7 mm) for most turf conditions. A greater cutting
depth may damage the root structure. IF the mower
slows down under load, it is an indication that the cut
may be too deep. Teeth should not penetrate into the
soil under any circumstances. To provide an even cut,
reels should be adjusted to the same depth below the
rollers within 0.015625 in (.39 mm) from end to end.
To make a cutting depth adjustment (Figure 13B-4),
loosen the locknuts on both sides enough to allow the
hand knobs to move the front roller brackets freely in
the side frames. Place a height adjusting gauge across
the two rollers outside the first blade on one end of the
reel and turn the reel to place one tooth of the blade at
90° to the top of the gauge. Adjust the reel visually to
the approximate depth desired. Check and make the
final adjustment with a scale to measure the distance
the tooth projects below the roller contacting the edge
of the gauge. Repeat the above on the opposite end of
the reel and tighten locknuts.
