to prevent injuries.

6 OPERATION

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.

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.
