ASSEMBLY
NOTE: Items in ( ) can be referenced in the Parts Illustrations and Parts Lists on pages 14-21.
1. Remove unit from carton and check the contents of the parts bag with the list above.
2. Remove mounting hardware from the hardware bag.
3. Attach the handle to the engine base with the items 62, 97, and 119.
4. Tighten mounting hardware on handle braces (items 5 and 6).
5. Attach guard bar (item 16) to Skid bar by installing the side bolts into the top two holes on the skids with items 103, 104
and 116.
6. Attach the throttle (30) to the right hand bracket (item 27) using the hardware (items 63 and 64). Tighten securely and
make sure the cable isn’t binding.
7. Attach the Blade drive cable to the lever and seat the plastic insert into the bracket on the left side of the handle.
8. Secure the drive and blade cables with the ty-wraps provided.
9. Place the shifter cable (item 41) into the bracket on the lower handle (item 14) with the nuts on both sides of the bracket.
10. Then attach the upper part of the cable to the shifter lever (item 21) using the nut located on the end of it and tighten

travel. If the lever does not have full travel loosen the nuts and either raise or lower them on the barrel to provide the
proper travel for the lever. NOTE: Putting too much tension on the cable can cause excess wear on the cable and lead
to failure. Likewise, if the cable is loose it will result in poor shifting.
11.Reconnect spark plug wire.
DISCONNECT spark plug wire before assembling unit.

2. Press blade clutch handle down (See Fig. 5) to engage blade. Allow
blade to spin up to normal operating speed.
3. Pull Up on the drive lever (See Fig. 6) to engage the transaxle in the
desired direction.
CLEARING ACLOGGED DECK
DISCONNECT spark plug wire before servicing unit.
1. Shut engine off and wait for blade to stop completely.
2. Disconnect spark plug wire.
3. Remove clog from cutting deck.
WEAR durable gloves. Clog may contain sharp materials.
4. Reconnect spark plug wire.
SHUT DOWN
1. Release drive lever (Fig. 6) to disengage transaxle.
2. Release blade clutch handle (Fig. 5) to disengage blade.
3. Move the throttle to the slowest possible position on the throttle control.
*****TIPS*****
The best performance is achieved when cutting in dry conditions. The quality of the cut is directly related to ground speed during
cutting. Under most conditions cutting should be done at a slower ground speed. Fast speeds should be reserved for conditions
where weeds and brush are thinned out or not very tall. If the quality of the cut is not satisfactory, attempt at slower speeds.

NOTE: Items in ( ) can be referenced in the Parts Illustrations and Parts Lists on pages 14-21.
BLADE SHARPENING AND REMOVAL (See pages 14 and 15 for Parts Illustration and Parts List)
READ all safety instructions before servicing unit.
1. Disconnect spark plug wire.
2. Lift and support front of unit to allow access to underside.
UNIT IS HEAVY. Make sure support is adequate to support weight of machine.
3. Block blade to prevent it from rotating during removal. When replacing the blade, use BILLY GOAT Industries PN 501224
only. NOTE: When sharpening blade make sure to sharpen all cutting edges. If the lock nut is removed and replaced more
than once, it should be replaced with a new lock nut (P/N 8160009).
4. Remove blade bolt (item 37), and friction washer (item 35).
5. Remove blade (item 45) and install replacement blade.
6. Attach new blade with new blade lock bolt (item 37), and new friction washer (item 35) removed earlier included with your
new blade. NOTE: Inspect fasteners for wear and replace if necessary.
7. Torque blade lock nut to 40 ft-lbs.
8. Reconnect spark plug wire.
BLADE DRIVE AND TENSION (See pages 14 and 15 for Parts Illustration and Parts List)
NOTE: The blade drive belt is under constant tension by the idler arm on the deck
DISCONNECT spark plug wire before servicing unit.
1. Disconnect spark plug wire.
2. Loosen two screws (item 75) holding belt deck cover (item 29) and remove the cover.
3. Examine condition of belt and amount of tension on belt.
4. If the idler is not providing enough tension inspect the spring (item 58) attaching it to the spindle base. If not enough
tension is being put on the arm, replace the spring.
5. Replace engine base door (item 29) and secure with screws removed earlier.
6. Reconnect spark plug wire.
7. Check belt tension by operating unit under conditions that caused belt slippage. If belt continues to slip it may require
replacement before operation may continue.
BLADE CLUTCH ADJUSTMENT (See pages 16 and 17 for Parts Illustration and Parts List)
DISCONNECT spark plug wire before servicing unit.
DISCONNECT spark plug wire before servicing unit.
If clutch continues to slip or squeal, do not operate equipment until adequate adjustment or repair has been
performed. Improper adjustment can cause clutch to overheat and slip, greatly reducing performance and
clutch life.
1. Disconnect spark plug wire.
2. As the clutch/brake wears or begins slipping or squealing, adjustment may
be required to maintain proper cable tension and clutch engagement. A
properly adjusted blade clutch should require 10 lbs. of force to depress the
end of the clutch lever. The blade clutch cable spring should stretch 1/4” to
3/8” (6.4-9.5 mm).
3. Adjust cable tension by tightening or loosening cable adjustment nut on rear
of engine base (see Fig. 8). Be sure to leave enough slack in cable to allow
blade brake to engage.
4. Reconnect spark plug wire.
