FRONT AND REAR MOWER MOUNTING
The mow ing uni t s hould b e placed in t he mac hine w ith
the rear roller on the table and front roller held in the
front tooling. The front tooling can be moved side to
side along t he too ling b ar s o they can b e posi tion ed as
far ap art as neces sar y to acco mmoda te al l reel wi dths.
Decals on the tooling bar make i t easy to position the
tooling based on the width of the reel. To move the
tooling, loosen the knob located at the front of the
tooling base and slide tooling along the tooling bar . The
tooling should be located as close to the frame as
possible leaving the maximum room to use the
position gauge (the gauge will be discussed in the
alignment section). The horizontal position is attained
by using the hand wheel located at the front of the
tooling. If yo u are gri nding a Quick Adjus t mow ing unit
(QA7 or QA5), use the decals loc ated on the tooling to
quickly position the reel. There are two positions for
each reel depending on how the front roller is mounted.
See FIG 2.
If you are using the all- pos it ion brac kets , the ver ti cal
and horizontal posi ti on c an be adj usted by l ooseni ng
the knobs located on the side of the tooling and
moving to a new set of pins.
Verify that the reel is positioned properly for the spin
wheel and relief wheel by checking the travel limits,
both wh ee ls will need to have clearance to come off
the reel on both sides. Checking during setup will
eliminate the need for major adjustments and
alignments when going from spin grinding to relief
grinding. W hen the mower is in place lock it into
posit ion by tigh tening all kno bs. L ift the rea r r oller onto
the angled bracket and clamp the roller firmly by
squeezing the clamp handl e.
REEL POSITION
The reel should b e positioned so that it i s at a o ne o’clock
or 30° angle position in reference to the grinding wheel.
See FIG 3. If the all - pos i ti on br ack ets ar e used tr y to
position the unit so that the bottom of the reel is
between 1.50-2.00" [38-51MM] off the table. W hen
using the roller mount styl e tooling try to maintain the
one o’clock positi on and check for clear ance between
the reel and grinding wheel. Verify that the proper relief
angle can be achieved with this setting and make
any adjustments i f necessary.

Retighten the ratchet handle when adjustment i s correct .
RELIEF WHEEL DIAMETER ADJUSTMENT
As the wheel wears, the finger system will need to be
adjusted to maintain the correct gap between the f ixed
finger and wheel. To move the finger system loosen the
small ratchet handle. See FIG. 6. The gap between the
fixed finger and the grinding wheel should be between
.06" [1.5 m m] and .18" [4.6 mm] dependi ng on the amou nt
of existin g relief on the reel . Retighten the rat chet handle
after the adjustment i s made.
INDEX FINGER ADJUSTMENTS
The R elief Assemb ly incl udes tw o fing ers. S ee FIG. 6. The
Fixed Relief Finger hold the blade in position during the
relief grind process. The Movable Index S top Finger moves
from the Relief Finger Side (back side) of the reel blade
when traversing from right to left, to the grinding wheel
side (front s ide) of the reel blade when traver sing from left
to right. T he indexing finger all ows the gr inder to index to
the next blade automatically during the relief grind.

IMPORTANT! After adjusting the Index Finger Stop
Position Knob there should be 1/32" [0.8 mm] clearance
between the index finger and the reel blade when you push
on the index finger . This will allow the Fixed Relief Finger
to guide the reel blade during the relief grind cycle. The
Reel blade should never be riding on the Index Finger
when grinding.
The Index Stop Pin is height adjustable. It should be
adjusted to catch the reel blade and still leave enough
clearanc e to the reel spider after the r elief i s gr ound to the
depth required.
There is a forward position stop on the Finger system
located near the pivot poi nt of the I ndex Finger . T his w ill only

ALIGNMENT GAUGE
A properly ground reel should be cylindrical. All taper
must be ground out of the reel. To ensure the reel will
be ground correct ly it MUST be aligned pr ecisely prior
to grinding. The digital alignment gauge is used for
accurate reel setup. The gauge is used for setting the
horizontal alignment and checking for taper within
thousands of an inch. The digi tal gauge al l ows y ou to
measure o ne end of the reel by extending the slide rai l
until you make c ontact w ith the cen ter shaft of the reel.
See FIG . 8. By measuring at the far left and the far right
on the center shaft you can adjust the horizontal
alignment using the front tooling adjustment knobs until
the alignment is w ithin .005 i nches [.13mm ].
When this is completed, you can then res et the gauge
to zero on the center shaft, retract the gauge slide
and measure the outer surface of a reel blade. By
comparing the readings on the left side of the reel to
the right side of the reel, you can determine exactly how
much taper you have in the reel. Compensating for
taper will be explained later in the grindin g proced ure.

JACOBSEN EQUIPMENT :
Below is a list of drive systems based on the cutting units:
* 5" reel units can be driven from the non hydraulic motor end of the reel. Install a 3/8" bolt in the end of the reel shaft
with a jam nut very tight so it does not loosen while spinning. Use a 9/16" socket to drive. They can also be driven from
the hydraulic motor end by pressing a Square Socket Drive Adapter [3/8" square male to 1/2" square female] into the
splined reel coupling Jacobsen part number 337370 and use this pressed as sembly as the adapter.
* 7" reel units can be driven from either end. The reel unit has a coupler attached to the reel shaft a both ends. Purchase
Jacoben part number 4102440 Reel Motor Shaft and weld the hydraulic motor shaft form the kit to a 1/2" socket and use
this weldment as the adapter.
* Tri-King reel units can be driven on older pulley drive units with a 9/16" socket on the 3/8" bolt that holds the pulley. On
newer splined units, purchase the splined reel coupling Jacobsen part number 132002 and press a S quare Socket Drive
Adater [3/8" square male to 1/2"square female] into the splined reel coupling and use this assembly as the adapter.

RECOMEN DA TION FOR SPI N DRIVE RPM A ND
TRANSVERSE SPEED WHEN GRINDING
SPIN DRIVE RPM
SPIN DRIVE RPM IS VERY IMPORTANT IN
ACHIEVING A QUALITY GR IND. USE C ARE IN
ESTABLISHING THE SPIN DRIVE RPM, PER THE
INSTRUCTIONS BELO W.
Generally, the Spin Drive RPM will be be tween 180
RPM (45%) and 380 RPM (100%). The speed required
to spin a specific reel is dependant on reel diameter,
the number of reel blades, and reel hardness. For all
reels, there i s an opti m um Spin Speed where ther e i s
an AGGRESSIVE, yet smooth grind as you spin gri nd
the reel. Your objective is to spin grind the reel as
aggressi vely and as fast as pos sibl e w hile m aint aining
top quality .
It is r ecommen ded to star t grinding eac h reel at a S pin
Speed of 200 RPM (50%) and evaluate the RPM by
adjusting hi gher and lower to opt imiz e the S pin S peed
for that reel. If the Spin Speed is incorrectly set, you
can experience two problems, grinding wheel
dressing or grinding w heel resonance. Each of these
problems is explained below .
On some reels, especially small diameter high blade
count reels if the Spi n S peed RPM is s et too high, the
reel can act as a dr esser to the grinding w heel. T here
can develop what appears to be a very aggressive
grind (as if the infeed has self infed) and then a
sudden stop of grinding with no grinding wheel to reel
contact. If this occurs, your Spi n Speed was set too
high and you effectiv ely dressed y our g rinding w heel.
Some ree ls have a res onant R PM w here the reel goes
into harmonics with the grinding wheel and the
resonance vibrates the grinder and results in a very
bad grind. By changing the Spin S peed to a higher or
lower RPM you will move out of the resonant range.
After determini ng the best S pin S peed RPM for a reel,
note the RPM on the "Set-up Chart" in the "NOTES"
section. (Set-up chart is located at the back of th is
manu al) By no ting th e correct RPM, you will a void
evaluating the Spin S peed the next time y ou grind the
reel. Also note the spin drive position using the
position decals on the spin mounting and
documenting the position on the "Set-up Chart".
TRAVERSE DRIVE RPM
The T raver se Speed potentiom eter is adjust able from
approximately 5 feet per minute [1.5 meters per minute]
to 20 feet per minute (6 meters per minute). It is
recommended to grind between 15 and 20 feet per
minute (4 and 6 meters per mi nute).
Gri nding a t a slow er tr aver se spee d, 10 feet p er min ute
(3 meters per minute) as an example, will give a better
finish but will extend the gri nd cycle ti me. Grind finish
versus grind cycle time is controlled by the choice of
the operator .
COMPENSATING FOR TAPER.
To maintain the best quality of cut, the taper in a reel
must be removed returning the reel to a true cylinder.
T o re move the t aper that w as measur ed with the gauge
(as discussed previously in Checking For T aper Section)
first align the reel to the shaft by the touch m ethod (as
discussed previously). Then drop the side of the
grinding shaft that is hi gh (the sm all er side of the reel )
the amount suggested in the chart
[See char t on next page or Compensation for
Taper Chart located on the machine].
Example: For a r eel that is 22 i nches [56 c m ] long
with a measur ed t aper of .12" [3 m m ],
the adjuster on the smaller side of the reel
would be dropped to read-.546 [13.9 m m].
This will bring the grinding shaft parallel to the reel
center shaft. Z er o out the di gi tal g auges loc ated on the
vert ical adj ustme nt tower s and infeed both side equal ly
until the wheel just touches the large side of the reel.
Zero the gau ges again, you are now rea dy to grin d and
remove the taper. When grinding, the wheel will only
make contact with the larger side of the reel and will
gradually grind more as the larger areas are ground
away. The reverse button may be used to help speed
of this process . Gri nd until full c ontact is made acros s
the entire length of the reel, and the reel is sharp the
entire width of all blades .
After the reel has been aligned and the taper has been
adjusted for , you ar e now ready to spin grind the r eel. Cl ose
the front and r ear guar d doors. (The g rinding w heel and spin
motors will not work unle ss th e doors are closed.) Position
the spin/relief selector switch to the spin position. Tu rn on
the Grinding M otor and the S pi n Dri ve M otor swi tch. Set the
spin speed at approximately 200 rpm (Refer to Spin Drive
RPM on per vious page) . M ake s ure spin r otation i s the same
as the grinding wheel – clockwise (CW) looking from right
end. See FI G 22.
IM PORTANT: When the reel turns i n the sam e rot ation as
the grinding wheel , the point of contact where they meet is
in opposit e direc tions.
Tur n on the tr averse dr ive m otor sw itch and turn the speed
dial up to approxi matel y 15- 20.
IM PORTANT: If the gri nd st arts get ting heav ier , adjust the
grindi ng head down u ntil yo u can tr avel th e full length of the
reel w ithout heav y grindin g.
When grinding, infeed the wheel approximately .005” [.13 mm]
at a time. Allow the grinding wheel to travel back and forth
across the reel 2 to 3 times before infeeding. The spin
grinding is completed when full contact is made across the
entire le ngth of the reel, the entire width of all bl ades and the
reel is s harp. The l ast pas ses shoul d be a norm al .005 [.13
mm] infeed gri nd at a slow trav erse speed (appr ox. 8 feet per
minute [2.5 meters per minute] or slo wer). Aft er the l ast pass
turn the grin der off.
(Note: Due to the positioning of the reel to the 1 o’ clock posi tion,
infeeding the wheel .015 inches [.38 mm] will remove .010
inches of material. )

LUBRICATION
LUBRICATION OF GRINDING SHAFT AND LINEAR BEARINGS
STEP 1 – Thoroughly c lean all three shafts.
STEP 2 – Flood spray all three shafts wi th CRC 3-36 until the lubricant is dripping off the shafts. (Do
not use a Tefl on-based lubri cant) Then run the grinding head ass em bl ies bac k and forth through
their full range of travel. This will remove the dust and deposits from inside the wheel flanges. Repeat
if necessary until l ubric ation is cl ear of deposits. Cl ean keyw ays l ocated on the gri nding shaft w ith soft
brush.
STEP 3 – With a clean rag, wipe off the excess amount of lubricant from the shafts. Run the gr inding
assemblies through their range of travel and w ipe the shafts after each traver se. Repeat until the
shafts are dry to the feel. This completes the lubri cation pr ocess.
IMPORTANT:
If the unit will be shut down for an extended period of time, more than four w eeks, then the shafts and
other appropriate par ts of the unit should be flooded with l ubric ant and that lubri cant left in pl ace until
the unit is brought back into serv ice. When the unit is brought back into service the full lubri cation
procedure as stated abov e should be repeated.

(See Traverse Belt Repl ac ement s ect i on)
REM OVING TH E TRA VER SE SHAFTS:
To remove the traverse shaft s use the ver tical
adjusters to low er both grindi ng shaft support arm s
until they are in there lowes t position. Now r emove
the left grindng s haft support arm. To remove the left
arm, first rem ove the bolt at the r ear of the machine.
(It may be neces sary to c lamp onto the s haft that the
bolt is screwed into s o that it does not spin.) After
removing the bolt, pull the arm off the rear shaft. Now
move the arm toward the r ear of the machine to
disengage the front of the arm from the vertical
adjuster. Next pull the arm aw ay from the gri nder
and off the traverse shafts. ( Note, the shafts may
come out of the r ight s i de ar m so support the shafts.)
Slide the Spin and Relief Gr inding Head Assem blies
off the traverse shafts.
Replace the s hafts if necessary .
REPLACI NG THE TRA VERSE BEARI NG:
T o r eplace the traverse beari ngs, press the bearings
out of the bearing housing. Sl ide in the new bearings
and secure in place with the seal s. (Two bearings go
in the front and 1 bearing the rear of the housing).
3. LIFT ARM OFF REAR
PIVOT SHAFT AND SLIDE
ARM BAC K THEN OUT.
TO REASSEMBLE:
Clean the 2 spher ical beari ngs in the right ar m
and place the trav erse shaft into the bear ings.
(The shafts should sl ide into the bearings.
There is ver y m ini m al c l ear ance s o the shafts
need to be preciesly aligned for the shafts to
slide into the bearings.) Next slide the gri nding
head assemblies ( spin firs t then r elief) onto the
traverse shaft s. Now , clean the bear ing in the
left arm. Then align the bearings i n the left arm
to the two traverse shafts. The shafts should
slide into the bearings . Reinstall the left arm
into the v ertical adj uster hous ing and onto the
rear support s haft. Reinstall the rear pivot bolt
and tighten. Continue to instal l the traverse
belt, gri nding sh aft, and gri nding m otor bel t.

CLEANING AND MAINTENANCE GUIDELINES FOR POLYCARBONATE
WINDOWS
Cleaning In str uction s
DO NOT USE GASOLINE
Adhe r en c e to r e gu la r and pr ope r
cleaning procedures is recommen ded
to preserve appearance and perform an ce.
Washing to Minimize Scratching
Wash polycarbo nate w indows w ith a mild dish w ashing liquid detergent and lukew arm w ater, using a clean
soft spon ge or a sof t c loth. Rinse w ell w ith clean w ater . Dry thorou ghly w ith a m oist c ellulose spo nge to
prevent water spots. Do not scrub or use brushes on these windows. Also, do not use butyl cellosolve in
direct sunlight.
Fresh paint splashes and grease can be removed easily before drying by rubbing lightly with a good
grade of VM&P naphtha or isopropyl alcohol. Af terward, a warm final wash should be made, using a mild
dish wa shing liquid detergent solution and ending with a thorough rinsing with clean water.
Minimizing Hairline Scratches
Scratc hes and minor abras ions can be minim ized by using a mild autom obile polish. Three such
product s that tend to po lish and fill scratches are Johnson pa ste Wax, No vus Plastic P olish #1 and #2,
and Mirror Glaze plastic polish (M.G . M10 ). It is suggested that a test be m ade on a corner of the
polycarbonate window with the product selected following the polish manufacturer's instructions.
Some Impo rtant "D ON'TS"
♦ DO NOT use abr asive or highly alkaline cleaners on the pol ycarbonat e window s.
♦ Never sc rape polycarbonate w indows wit h squeegees, razor blades or other sharp
instrument s.
♦ Benzene, gasoline, aceton e or c arbon tet rachloride should NEVER be used on polycarbona te
windows.
♦ DO NOT clean polycar bonate windo ws in hot sun or at elevat ed tem pera tures.
•The use of m asking tape, adhesive tape or lint removal tools works well f or lifting off old
weathered paints.
•T o rem ove labels, stickers, etc., the use of kerosene, VM &P naphtha or petroleum spirits is
generally effective. When the solvent will not penetrate stickier material, apply heat (hair
dryer) to soften the adhesive and promote removal.
GASOLINE SHOULD NOT BE USED!

CONTROL BOARD POTENTIOMETER ADJUSTMENTS (Continued)
SPIN DRIVE CONTROL BOARD (SDC)
The Spin Drive Control Board has four potentiometers, two switches and one dial as shown on FIG. 24. These
potentiometers,swtiches and dial have been set at the factory to the positions shown on FIG . 24.
In the Relief Gr inding Mode--
The T orque Shut Off mode selector allows you to turn on or off the T orque Shut Off feature. When switch 1 is set to ON, the
board w ill decrease t he sp in motor torque on ce the shu t time is achieved after leaving the right pro ximity sens or . The amount
of ti m e i t takes bef ore t he torque i s decreased is set with t he Torque Shut O ff Del ay di al . The spin m ot or toque will be
increased to the higher value once the right proximity switch is activated again. If the T orque Shut Off selector is in the OFF
position the torque will rema in co ns tan t du ring relie f grind ing . Th is s hould be set to OFF.
T orque Shut Off Delay dail is used to set the duration of time before the torque is decreased after leaving the right proximity
sensor during relief grinding. If the dial is turned clockwise (higher number) the higher torque value will stay on fo r a lon ger
period of time.
The Relief Speed (RSP) and the Relief T orq ue Pot (R TP) interact with each ot her . The (RSP) is located on the s pin board as a
remote speed preset at 12:00 (20 Volts DC). See FIG. 24. The (RTP) is located on the control panel and is for relief torque
adjustment.
Relief S peed Pot (SPEED) when r otated clockwise will in cr eas e s pin d rive speed (the speed at which the reel indexes to the
next blade). This speed should never be above the 3:00 setting.
Relief T orque Pot (TORQ) is us ed to vary the reel to finger holding torque for relief grinding. The
recommended starting point is 30 in/lbs of torque setting. Never adjust the (RTP) potentiometer dial past the red line marking.
Setting the reel to finger torque to high could cause the spin motor system to not operate smoothly.
Relief Idle T orque Pot (ITP) is used to vary the reel to finger holding torque once the shut time is achieved after leaving the right
proximity sensor if the Torque Shut Off Selector is set to on.
In the Spin Grinding Mode- -
The S pin Torque P otentiometer (STP) and the S pin S peed Pot (SSP) inte ract with ea ch other . The (STP) is located on the sp in
board as remote torque pres et at 2:00 for torque s etting. See FIG . 24. T he (SSP) is located on the control pan el and is for sp in
speed adjustment.
Spin T orque Pot (STP) controls maximum torque allowable in the spin grinding cycle only. This should never be adjusted past
the 3:00 position. If the reel does not turn check that the reel is free turning by hand spinning with the power off and the spin
drive disconnected.
The Spin speed Pot (SSP) controls reel spin speed, adjust as required. This controls the spin drive speed for spinning the reel.
IR CO MP Pot --
The IR Compensation is factory set at 9:00.
Regulation o f the spin or relief grind s pin motor may be improved by a slight adjustment of the IR COMP p ot clockwis e from its
factory-set position. Overcompensation causes the motor to oscillate or to increase speed when fully loaded. If you reach such
a point, turn the IR COMP pot counterclockwise until symptoms just disappear.
