operating procedure. Consider the height of the
grass, type of terrain, and condition of the surface.
Each condition will require certain adjustments or
precautions.
5. Never direct discharge of material toward
bystanders, nor allow anyone near the machine
while in operation. The owner/operator is
responsible for injuries inflicted to bystanders and/or
damage to their property.
6. Use discretion when operating near gravel areas
(roadway, parking areas, cart paths, etc.). Stones
discharged from the implement may cause serious
injuries to bystanders and/or damage the
equipment.
7. Always turn PTO off to stop blades when not
mowing.
8. Disengage the PTO and raise the attachments when
crossing paths or roadways. Look out for traffic.
9. Stop and inspect the equipment for damage

6.3 AERATOR OPERATION ____________________________________________________
1. The blades of the 548 Aerator may be operated in
forward or reverse rotation (Section 6.6).
a. Forward blade rotation produces better verifica-
tion and makes a cleaner cut.
b. Reverse blade rotation lifts more soil to the sur-
face and produces an uneven and ragged cut.
Requires more horsepower.
2. The direction of rotation should be made consider-
ing the tractor available, aerating requirements, con-
dition and use of the turf and the season of the year.
3. Start the engine and raise Aerator off the ground,
engage PTO and gradually increase PTO speed to
540 RPM while observing blades, PTO shaft and
universal joints.
4. With tractor forward speed at 4 to 5 MPH and the
PTO speed at 540 RPM, gradually lower Aerator to
cutting position.
5. Tractor ground speed and blade cutting depth
should be reduced if operating on dry and hard soil.
6. Always operate Aerator in a straight line; never
attempt to make turns while cutting. Raise Aerator
just high enough to clear surface of ground then
make the turn.
7. If Aerator vibrates excessively, stop immediately.
Vibration is caused by low PTO speeds or blade
cutting depth is too great. Continued operation
under these conditions can cause severe damage to
the equipment.
6.4 SEEDER OPERATION ______________________________________________________
1. To set indicator arm, loosen both nuts (A and B) on
flow gauge. Move nut (A) as far as necessary then
turn nut (B) to place the pointer (C) at desired set-
ting.
2. Use line 1 or 2 in the chart as reference (See Page
11). The flow rates (pounds of seed per acre) are
approximate and trial settings will be necessary.
Once the desired setting is obtained, record that
number in line 3 of the chart for future use.
3. Clean Seeder thoroughly after each use. Make sure
that all seeds have been removed.
4. Any seed left in the feed rolls, gears or tubes could
germinate and damage the equipment.
Figure 6A
CAUTION
Do not raise unit so high as to bend PTO universal
joints. Never engage PTO with aerator blades on or in
the ground.

WARNING
I M P O R T A N T
T h i s seeder has a sheer bolt in the
drive sprocket to prevent feed shaft
breakage should feed rolls become
clogged. If feed mechanism fails clear
feed rolls before replacing sheer bolt.
1. Clean seeder attachment #548100 thoroughly after each use.
2. Make sure that all seed has been run through and that none remains in the seed feed rolls,
seed gears and seed tubes.
3. Any seed left in these ares can germinate and block up seeder unit.
4. Before using seeder pull discs through by hand to make sure feed rols are not blocked.
5. When it is desired to close the flo rate gauge, do not go beyond the zero settings as it will put
undue pressure on the feed shaft.
6. Check chain tightness and grease chain and bearings lightly after forty hours of operation.
