....STOP" position.

ToEngageDrive&Tines

For forward motion of the wheels and power to the tines pull the Forward Clutch Bail up against the handlebar. Release the bail to stop the forward motion of wheels and

tines.

2. When tilling, relax and let the wheels pull the machine while the tines dig. Walk behind and a little to one side of the tiller. Use one hand, yet keep a light -- but secure -- grip on the handlebar while keeping your arm loose.

3. Let the tiller move at its own pace and do not push down on the handlebars to try and force the tines to dig deeper

-- this takes weight off the wheels and reduces traction.

WARNING! Do not push down on the handlebars to try to make the tiller till more deeply. This

prevents the wheels from holding the tiller back and can allow the tines to rapidly propel the tiller

forward, which could result in loss of control,

property damage, or personal injury.

To move in

reverse:

Release the forward Clutch Bail. Then lift the

handlebar until the tines are off the ground.

Pull back on the Reverse Lever, and walk backwards with the machine

Note: In reverse mode, the tines will reverse

rotation.

If longer distances need to be covered in reverse, shut offthe engine, then place the two wheels in

FREEWHEEL.

Setting TheDepth

Tilling depth is controlled by the depth stake which can be adjusted to five different settings. Adjust the side shields as you

adjust the depth stake.

_ ARNING: Be certain spark plug wire is

To adjust the depth stake, pull back on the depth adjustment bracket (A) and push up or down (B) until the bracket reaches the desired position, see Fig. 5-1, then release the bracket (C).

To adjust the side shields, remove the wing nuts. Move the side shield to the desired position and replace the wing nuts. Tighten

disconnected and grounded against the engine

when performing any adjustments.

When using the tiller for the first time, use the second adjustment hole from the top (1" of tilling depth).

When breaking up sod and for shallow cultivation, use the setting which gives 1" of tilling depth (second hole from the top). Place the side shields in their lowest position.

For further depth, raise the depth stake and side shields and also make one or two more passes over the area.

When tilling loose soil, the depth stake may be raised to its highest position (use bottom adjustment hole) to give the deepest tilling depth. Raise the side shields to their highest position.

To transport tiller, lower the depth stake (use top adjustment hole).

Turning the Tiller

1. Practice turning the tiller in a level, open area. Be very careful to keep your feet and legs away from the tines.

2. To begin a turn, lift the handlebars until the tines are out of the ground and the engine and tines are balanced over

the wheels.

With the tiller balanced, push sideways on the handlebar to steer in the direction of the turn. After turning, slowly lower

the tines into the soil to resume tilling.

Figure 5-2

SECTION S -- OPERATION 13

Adjustingthe HandleHeight

The handle should be adjusted so that when the tiller is digging 3-4" into the soil, the handle falls to about waste-high. To adjust

handle, simply loosen the handle adjustment crank, move the handle to the desired height and retighten the adjustment crank. See Fig. 5-3.

Clearingthe Tines

The tines have a self-clearing action which eliminates most of the tangling of debris. However, occasionally dry grass, stringy stalks or tough vines may become tangled. Follow these procedures to help avoid tangling and to clear the tines, if necessary.

To reduce tangling, set the depth regulator deep enough to get maximum "chopping" action as the tines chop the

material against the ground. Also, try to till under crop residues or cover crops while they are green, moist and

tender. While tilling, try swaying the handlebars from side to side

(about 6" to 12"). This "fishtailing" action often clears the tines of debris.

WARNING! Before clearing the tines by hand, stop the engine, allow all moving parts to stop and

disconnect the spark plug wire. Failure to follow this

warning could result in personal injury.

This is a CRT (counter-rotating tine) tiller. As the wheels pull forward, the tines rotate backward. This creates an "uppercut" tine action which digs deeply, uprooting soil and weeds. Don't overload the engine, but dig as deeply as possible on each pass. On later passes, the wheels may

tend to spin in the soft dirt. Help them along by lifting up slightly on the handlebar (one hand, palm up, works most easily).

Avoid the temptation to push down on the handlebars in an attempt to force the tiller to dig deeper. Doing so takes

the weight off the powered wheels, causing them to lose traction. Without the wheels to hold the tiller back, the tines will attempt to propel the tiller backward, towards the operator.

When cultivating (breaking up the surface soil around the plants to destroy weeds, see Fig. 5-4), adjust the tines to dig only 1" to 2" deep. Using the shallow tilling depth helps prevent injury to the plants whose roots often grow close to the surface. If needed, lift up on the handlebars slightly

to prevent the tines from digging too deeply. (Cultivating on a regular basis not only eliminates weeds, it also loosens and aerates the soil for better moisture absorption and faster plant growth.) Watering the garden area a few days

prior to tilling will make tilling easier, as will letting the newly worked soil set for a day or two before making a final, deep tilling pass.

ChoosingCorrectWheel& TineSpeeds

With experience, you will find the tilling depth and tilling speed combination that is best for your garden. Set the engine throttle lever at a speed to give the engine adequate power and yet allow it to operate at the slowest possible speed until you have

achieved the maximum tilling depth you desire. Faster engine speeds may be desirable when making final passes through the seedbed or when cultivating. Selection of the correct engine speed, in relation to the tilling depth, will ensure a sufficient power level to do the job without causing the engine to labor.

SuggestedTilling Patterns

When preparing a seedbed, go over the same path twice in the first row, then overlap one-half the tiller width on the

rest of the passes. See Fig. 5-5.

If the garden size will not permit lengthwise and then crosswise tilling, then overlap the first passes by one-half a tiller width, followed by successive passes at one-quarter

width. See Fig. 5-7.

When finished in one direction, make a second pass at a right angle, as shown in Fig. 5-6. Overlap each pass for the best results (in very hard ground, it may take three or four

passes to thoroughly pulverize the soil.)

freewheel down slopes. Failure to follow this warning could result in personal injury.

1. Till only on moderate slopes, never on steep ground where the footing is difficult.

2. Tilling up and down slopes is recommended over terracing. Tilling vertically on a slope allows maximum planting area

and also leaves room for cultivating. NOTE:When tilling on slopes, be sure the correct oil level

is maintained in the engine (check every one-half hour of operation). The incline of the slope will cause the oil to slant away from its normal level and this can starve engine

parts of required lubrication. Keep the motor oil level at the full point at all times.

1. To keep soil erosion to a minimum, be sure to add enough organic matter to the soil so that it has good moisture- holding texture and try to avoid leaving footprints or wheel

marks.

When tilling vertically, try to make the first pass uphill as the tiller digs more deeply going uphill than it does

downhill. In soft soil or weeds, you may have to lift the handlebars slightly while going uphill. When going downhill, overlap the first pass by about one-half the width

of the tiller.
