FLOATING HEAD REEL ADJUSTMENTS
7.1
GENERAL ________________________________________________________________
!
WARNING
Before you adjust, clean, or repair this equipment,
always disengage all drives, engage parking brake,
turn power off and disconnect power connector to
prevent serious injury.
1. Adjustments and maintenance should always be
performed by a qualified technician. If proper
adjustment cannot be made, contact an authorized
Jacobsen Dealer.
7.2
BEDKNIFE-TO-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
7.5.
!
CAUTION
To prevent personal injury and damage to the cutting
edges, wear gloves and handle the reel and bedknife
with extreme care.
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 bed-
knife. 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.

CAUTION
Be careful to prevent entrapment of the hands and
fingers between moving and fixed components of the

4.
Do not change speed limit settings or overspeed the
drive motors.
a.
Dry, sparse conditions will require a wider gap to
prevent heat buildup and damage to the reel and
bedknife.
b.
High quality grass with a good moisture content
requires a closer gap (near zero).
