TILLING HINTS

CAUTION:  Until you are accustomed to 
handling your tiller, start actual fi eld 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.

•         Soil conditions are important for proper tilling. Tines will 

not readily penetrate dry, hard soil which may con trib ute 
to excessive bounce and diffi cult 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.

•      You will fi nd 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.

•         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. 

TO START ENGINE (See Fig. 13)

CAUTION:  Keep drive control bar in 
“DISENGAGED” position when start-
 ing en gine.

When starting engine for the fi rst time or if engine has run 
out  of fuel, it will take extra pulls of the recoil starter to 
move fuel from the tank to the engine.
•      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 fi res 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.

•      Move throttle control to desired running position.
•     Allow engine to warm up for a few minutes before 

engaging tines.

NOTE

:  If at a high altitude (3000 feet) or in cold 

temperatures (below 32°F), the carburetor fuel mixture 
may need to be adjusted for best engine performance. 
See "TO ADJUST CARBURETOR" in the Service and 
Adjustments section of this manual.

NOTE

:  If engine does not start, see troubleshooting 

points.
