100380 - REAR TINE TILLER
To alleviate high altitude issues other than the natural power
loss, CPE can provide a high altitude carburetor main jet. The
alternative main jet and installation instructions can be obtained
by contacting our Technical Support Team. Installation instructions
are also available in the Technical Bulletin area of the CPE website.
The part number and recommended minimum altitude for the
application of the high altitude carburetor main jet is listed in the
table below.
In order to select the correct high altitude main jet it is necessary
to identify the carburetor model. For this purpose, a code is
stamped on the side of the carburetor. Select the correct high
altitude jet part number corresponding to the carburetor code
found on your particular carburetor.
Carb. Code High Alt. Jet Part Number
16161-Z151510-0000
16100-
Z142910-
00M1
16161-Z151310-0000
Operation using the alternative main jet at elevations lower
than the recommended minimum altitude can damage the
engine. For operation at lower elevations, the originally
supplied standard main jet must be used. Operating the
engine with the wrong engine configuration at a given altitude
may increase its emissions and decrease fuel efficiency and
performance.
TILLING TIPS AND TECHNIQUES
Tilling Depths
Before tilling, contact your telephone or utilities company and
inquire if underground equipment or lines are used on your
property. Do not till near buried electric cables, telephone
lines, pipes or hoses.
Avoid pushing 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
helping to hold the tiller back, the tines will attempt to propel the
tiller – often causing the tiller to skip rapidly across the ground.
(Sometimes, slight downward pressure on the handlebars will
help get through a particularly tough section of sod or unbroken
ground, but in most cases this wont be necessary.)
Min. Altitude
3000-6000 ft.
(914.4-1828.8 m)
6000-8000 ft.
(1828.8-2438.4 m)
WARNING
WARNING
Avoid trying to dig too deeply too quickly, especially when busting
sod or when tilling soil that hasn't been tilled for some time. Use
shallow depth regulator settings (only an inch or two deep) for
the first passes through the soil. With each succeeding pass, dig
another inch or two deeper. (Watering the area a few days prior to
tilling will make the tilling easier, as will letting the newly worked
soil set for a day or two before making a final, deep tilling pass.
When cultivating (breaking up surface soil around plants to
destroy weeds), adjust the tines to dig only 1 in. to 2 in. (2.5 to
5 cm) deep. Using shallow tilling depths helps prevent injury to
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.)
Choosing Correct Wheel and Tine Speeds
With experience, you will find the "just right" 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 ... at least 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.
Let the Tiller Do the Work
While tilling, relax and let the wheels pull the tiller along while the
tines do the digging. Walk on the side that is not yet finished (to
avoid making footprints in the freshly tilled soil) and lightly, but
securely grip the handlebar with just one hand.
Avoid Tilling Soggy, Wet Soil
Tilling wet soil often results in large, hard clumps of soil that can
interfere with planting. If time permits, wait a day or two after
heavy rains to allow the soil to dry before tilling. Test soil by
squeezing it into a ball. If it compresses too easily, it is too wet to
till.
Preparing Seedbeds
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. When finished in one direction, make a second pass at
a right angle. Overlap each pass for best results (in very hard
ground, it may take three or four passes to thoroughly pulverize
the soil.)
