OPERATION

•

Soil conditions are important for proper tilling. Tines will

not readily penetrate dry, hard soil which may con trib ute

to excessive bounce and difficult handling of your tiller.

Hard soil should be mois tened before tilling; however,

extremely wet soil will “ball-up” or clump during tilling.

Wait until the soil is less wet in order to achieve the

best results. When tilling in the fall, re move vines and

long grass to prevent them from wrapping around the

tine shaft and slowing your tilling operation.

•

Do not lean on handle. This takes weight off the wheels

and reduces traction. To get through a really tough

section of sod or hard ground, apply upward pressure

on handle or lower the depth stake.

CULTIVATING

Cultivating is destroying the weeds between rows to pre-

vent them from robbing nourishment and moisture from the

plants. At the same time, breaking up the upper layer of

soil crust will help retain moisture in the soil. Best digging

depth is 1" to 3" (2.5-7.5 cm). Lower the outer side shields

to protect small plants from being buried.
• Cultivate up and down the rows at a speed which will

allow tines to uproot weeds and leave the ground in

rough condition, promoting no further growth of weeds

and grass (See Fig. 15).

TILLING HINTS

CAUTION: Until you are accustomed to

handling your tiller, start actual field use

with throttle in slow position (mid-way

between “FAST” and “IDLE”).

• Tilling is digging into, turning over, and breaking up

packed soil before planting. Loose, unpacked soil helps

root growth. Best tilling depth is 4" to 6" (10-15 cm).

A tiller will also clear the soil of unwanted vege ta tion.

The de com po si tion of this vegetable mat ter enriches

the soil. Depending on the climate (rain fall and wind),

it may be advisable to till the soil at the end of the

growing season to further condition the soil.

• You will find tilling much easier if you leave a row un-

tilled between passes. Then go back between tilled

rows. (See Fig. 14) There are two reasons for doing

this. First, wide turns are much easier to negotiate than

about-faces. Sec ond, the tiller won’t be pulling itself,

and you, toward the row next to it.

TINE SHEAR PINS

The tine assemblies on your tiller are secured to the tine

shaft with shear pins (See “TINE REPLACEMENT” in the

Service and Ad just ments section of this manual).
If the tiller is unusually overloaded or jammed, the shear

pins are designed to break before internal damage occurs

to the trans mis sion.
•

If shear pin(s) break, replace only with those shown in

the Repair Parts section of this manual.

CHOKE CONTROL

RECOIL STARTER

HANDLE

•  Make sure spark plug wire is prop er ly connected.
•  Move shift lever indicator to “N” (neutral) position.
•  Place throttle control in “FAST” position.
•  Turn fuel shut-off valve 1/4 turn to open position.
•  Move choke control to choke position.
•  Grasp recoil starter handle with one hand and grasp

tiller handle with other hand. Pull rope out slowly until

engine reaches start of com pres sion cycle (rope will

pull slightly harder at this point).

• Pull recoil starter handle quickly. Do not let starter

handle snap back against starter.

• If engine fires but does not start, move choke control

to half choke position. Pull recoil starter handle until

engine starts.

• When engine starts, slowly move choke control to

"RUN" position as engine warms up.

NOTE

: A warm engine requires less choking to start.
