Section 2 - OPERATING INSTRUCTIONS

2.1 BEFORE OPERATING:

FIGURE 2

Be thoroughly familiar with the operation of ALL controls

and how to use them BEFORE operating your Tiller.

Transmission shifting is done by shifting the WHEEL

and TINE SHIFT LEVER into the desired position.

Refer to Figure 3.

When activated, the tines rotate in a rearward (Reverse)

direction ONLY. With the engine running, shift into the desired

transmission position and pull the WHEEL and TINE

CONTROL BAIL against the handle bar to start wheel or

wheel and tine rotation.

Wheel or wheel and tine rotation is STOPPED by releasing

the WHEEL and TINE CONTROL BAIL. When the bail is

released, rotation should STOP even with the WHEEL and

TINE SHIFT LEVER in an engaged position. See Figures 3

and 4.

2.1.1 TRANSMISSION POSITIONS

The Tiller has four transmission positions:

NOTE: The four different transmission positions shown on

the cover are close to actual positions of shift lever but are

not exact. Use positions as a reference.

1. FWD & TIL - (FORWARD and TILL) (Wheels and

Tines

are engaged).

2. FWD - (FORWARD) (Only the Wheels are engaged).

3. NEU - (NEUTRAL) (Wheels and Tines are disengaged).

4. REV - (REVERSE) (Rearward Wheel rotation).

2.2 PRE-START CHECKLIST

Make the following checks and perform services as

required before each start up. NOTE: Before checking

oil level place 2x4 piece of wood under both wheels to

level engine.

2.2.1 CHECK ENGINE OIL and bring level up to full.

(Refer to engine manual for oil specifications).

2.2.2 CHECK AIR CLEANER and service according to

instructions in engine manual.

2.2.3 CHECK EXTERNAL SURFACES and remove dirt

and dust accumulation and clean tines as needed.

2.2.4 CHECK GUARDS to make sure all are in proper

position and securely tightened.

2.6.1

FORWARD/REVERSE: To transport the Tiller to

a new tilling site using its own power, raise the tines to clear

lawn and paved surfaces to prevent gouging. Release the

WHEEL and TINE CONTROL BAIL and lift the rear of the

Tiller to take the weight off the DEPTH BAR (see Figure 7),

then push the DEPTH BAR downward into notch setting

that allows the tines to clear the ground surface. Place the

WHEEL and TINE SHIFT LEVER in FWD or REV. Pull the

WHEEL and TINE CONTROL BAIL back against the

handlebar to engage the wheel drive and transport the unit.

2.7.1 TILLING HINTS: Let the Tiller do the work!

DO NOT try to hold it back. If forward motion ceases

while tilling deep, lift up slightly on the handle bar to

resume moving forward.

2.7.2 ROUGH TERRAIN HINT: If tilling over very

rough, uneven ground, till at a shallow depth setting

on the first path to smooth the surface.

especially rough terrain, the Tiller could hang up

underneath with the wheels spinning freely. Under

this condition, lift the handle bar, then turn the tiller

diagonally uphill to regain traction.

3.1 SERVICE PARTS & ASSISTANCE

3.3 TILLER LUBRICATION

To retain the original quality of your Tiller, use only

genuine SNAPPER replacement parts. Specify the

model and serial number as found on the

nameplate of your Tiller when contacting your

SNAPPER Dealer for parts or service assistance.

CHAIN CASE: Check the level of the grease in the

chain case at the beginning of each tilling season.

Remove clevis pin and cotter pin that secures left

hand tire/wheel to axle. Remove wheel. Check

grease level by removing the plastic plug located

beside the axle shaft on the lower left hand side.

See Figures 9A. The level should be up to the edge

of the opening. To add grease, remove the filler

plug located just forward of the pulley shaft on the

right hand side. See Figure 10. Add Snapper Part

No. 2-9577 Benalene 900 grease (4 oz. Bottle) as

needed to bring level up to bottom edge of the

check plug opening. The total capacity of the case

is about 48 ounces. DO NOT exceed this amount.

Reinstall check plugs after checking. NOTE: Also

available Snapper Part No. 2-9296 Benalene 900

grease (32 oz. Bottle).

3.2 STANDING THE TILLER ON END

WARNING

ALWAYS STOP the engine and DISCONNECT the spark

plug wire BEFORE standing the TILLER on end to

prevent accidental starting! NEVER stand Tiller on end

with the engine running!

WARNING

If the fuel tank is over half full when the Tiller is placed on

end, gasoline may leak from the carburetor vent hole and

drip down the outside surface of the engine creating a

potential FIRE HAZARD! Gasoline may also leak unnoticed

into the engine cylinder and wash away lubricating oil

causing engine damage. Take all necessary precautions to

prevent fuel leakage BEFORE standing the Tiller on end.

Any draining of fuel must be done outside with the engine

cool and away from ignition sources. If the Tiller is stored on

end for any length of time, check it frequently for signs of fuel

and/or oil leakage.

3.4 TILLER TINES

1/4” TO 1/2”

Your Snapper Tiller has right hand and left hand

tines. Replace both tines if blades become bent or

are badly worn or otherwise damaged. Use correct

Snapper replacement tines. The tines are secured

to the tine shaft with a shear bolt, Part No. 2-8725

BELT

GUIDE

and Lock Nut Part No. 9-0222 on each side. NOTE:

Two extra nuts and two bolts come with tiller. Keep

spares on hand in case a bolt shears off or

becomes lost while tilling. See Figure 11. DO NOT

over tighten these shear bolts as this will cause

premature failure. (Recommended torque is 5 to 8

foot pounds maximum). NOTE: Failure to use the

correct shear bolts could result in serious damage

to your Tiller. Use only the genuine Snapper

replacement bolts and lock nuts specified above.

These bolts are designed to shear at a specific

stress to prevent damage. DO NOT use substitutes!

3.5.2 BELT REPLACEMENT: Pull the clevis pin from

the left wheel and slide the wheel out 1”, remove belt

guard and then the old belt. NOTE: Replacement belt

must go over the top of the idler and be within the belt

guide as shown in Figure 14. Check belt tension as

described in BELT TENSION ADJUSTMENT Section.

Reinstall guard, push left wheel back into position and

secure with clevis pin and insert and secure cotter pin.

BELT TENSION ADJUSTMENT: Remove the cotter

pin that secures clevis pin to left wheel hub. Remove

clevis pin from left wheel hub and slide wheel out on

axle about 1”. Remove belt guard. Measure the

length idler pulley spring at the end of the control

cable in a relaxed position. Then move wheel and

tine control bail up to the handle bar and measure

the extended length of the spring. When properly

adjusted, the spring will extend 1/4” to 1/2”. See

Figure 12. To adjust, loosen and reposition the two

jam nuts on the threaded end of cable located on the

dash panel. Move jam nuts toward the end of

threaded end of cable for more tension. Move jam

nuts in a direction away from the end of threaded

end of cable for less tension. See Figure 13. After

adjustment, retighten both jam nuts against dash

panel. Reinstall belt guard. Slide wheel back into

operating position and reinstall clevis pin and secure

with hair pin.

crank-case oil and add gasoline to the fuel tank after

returning the Tiller to its wheels.

Thoroughly clean all external surfaces and tines before

storing the Tiller. The Tiller may be stored on end,

however, the following steps must be taken:

5. Before starting, move the ENGINE CONTROL to

STOP and pull rope starter slowly several times. If

excessive resistance is felt, remove the spark plug

and pull rope starter rapidly to spin the engine and

clear oil from the cylinder. Clean and reinstall spark

plug before attempting to start the engine.

1. Drain gasoline from fuel system and drain the engine

crankcase oil (refer to engine manual for details).

2. After standing the Tiller on end, check the plugs in the

chain case for leakage. After extended period, some

grease may seep thru upper bearing races.

3. Remove both wheels and grease wheel shafts.

Reinstall wheels. Remove both tines and grease tine

shafts. Reinstall tines. Grease these shafts when tiller

is stored for long periods of time to prevent rust

buildup. Rust buildup will cause wheels and tines

difficult to remove.
