Tilling is digging into, turning over, and
breaking up packed soil before
planting. Loose, unpacked soil helps
root growth. Besttilling depth is 4" to 6".
A tiller will also clear the soil of un-
wanted vegetation.The decomposition
of this vegetable matter enrichesthe
soil. Dependingon the climate (rainfall
and wind), it may be advisableto till the
soil at the end of the growingseasonto
further condition the soil.
Soil conditions are important for proper
tilling. Tines will not readily penetrate
dry, hard soil which may contributeto
excessive bounce and difficult handling
of your tiller. Hardsoil should be
moistened before tilling; however,
extremely wet soil will "ball-up" or
clump during tilling. Wait untilthe soil is
less wet in orderto achieve the best
results.When tilling in the fall, remove
vines and longgrass to prevent them
from wrapping around the tine shaft
and slowing your tilling operation.
You will find tilling much easier if you
leave a row untilled between passes.
Then go back between tilled
rows.Thereare two reasonsfor doing
this. First,wideturns are much easier to
negotiate than about-faces. Second,
the tiller won't be pulling itself,and
you,toward the row nextto it.
Do not lean on handle. This takes
weight off the wheels and reduces
traction. To get througha reallytough
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 prevent 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.
Do not lean on handle, this takes
weight off the wheels, reduces traction,
and may cause the tiller to skip over the
ground.
Always lower the drag stake when
using the forward rotating tine drive.

TINE SHEAR PINS
The tine assemblies on your tiller are
secured to the tine shaft with shear pins
(See 'q'INE REPLACEMENT" in the
Service and Adjustments 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 transmission.
If shear pin(s) break, replace only with
those shown in the Repair Parts
section of this manual.
