Troy-Bilt 12087 - Manual (Page 33)

To Change From HIGH Range to
LOW Range
1. To avoid personal injury, shut
off engine, let all moving parts
come to a complete stop, then dis­
connect spark plug wire and move
it away from the spark plug before
making any adjustments.
2. Move the Wheel s/Tines/PTO
Drive Lever to NEUTRAL.
3. Stand on left side of tiller. Use
your right hand to hold the
Wheels/Tines/PTO Drive Lever UP
in REVERSE position. Then use
left hand to move belt from front
groove to rear groove on the en­
gine pulley (top pulley). Refer to
Photo 4-15. Go to right side of
tiller and finish seating the belt.
4. Still holding the lever up in RE­
VERSE position, move the belt
Choosing Tiller Wheel
and Tine Speeds
Your tiller o f f e r s four wheel/tine
speed combinations to handle ev­
ery tilling task and garden job. By
experimenting, you’ll find the right
tilling depth, engine speed, and
wheel and tine speed combination
that is best for the soil in your gar­
den. Here’s how to approach jobs:

Drive Lever held UP in REVERSE,
move belt on engine (upper) pulley
over into its rear groove.
from the front groove to the rear
groove on the lower transmission
pulley. Start at the left side of the
tiller and finish seating the belt
from the right side (Photo 4-16).
1. Advance the throttle lever so
the engine has sufficient power.
2. Do not set the depth regulator at
too deep a setting to avoid having
the engine labor or the tiller buck.
3. Your settings are “ideal” when
the tines are breaking up the soil
nicely, the engine is not laboring,
and your progress is steady and
smooth. See the Selection Guide
below for hints.
Photo 4-16: Now move belt on
transmission pulley (lower pulley)
over into its rear pulley groove.
5 . Check that the belt is fully
seated in the pulley grooves. Look
at this from both sides of the tiller.
WARNING
The HIGH speed belt range
position combined with a
FAST wheel speed setting
propels
the tiller at the
fastest pace. To help avoid
personai injury or property
damage if using this speed
comhination, reduce the en­
gine throttle speed.
WHEEL SPEED AND BELT RANGE SELECTION GUIDE
IMPORTANT — For correct wheel speed and belt range choices when using attachments or accessories
other than tines, read the Owner/Operator Manual provided with the attachment or accessory.
SLOW GEAR, LOW BELT RANGE
Till in sod.
Till in hard clay.
Till under standing cornstalks
in tough soil conditions.
Till under cover crops.
Prepare a deep seedbed.
Till in stony soil.
Till in residues and organic
matter.
Mix in fertilizers, manure.
SLOW GEAR, HIGH BELT RANGE
Till in sod or hard clay.
Till under standing cornstalks
(slow, steady speed allows
time to shred stalks).
Till under cover crops (best
wheel speed and belt speed
range in most soils).
Prepare seedbeds (best speed
choice in most soils).
Till in stony ground.
Build raised garden beds.
Mix in fertilizer.
Use hiller wings in hard soil.
Mix fertilizer and manure.
Till residues, organic matter.
FAST GEAR, LOW BELT RANGE
Go over seedbed for the last
time before planting crops.
Cover over seeds in wide row
or plot planting (raise han­
dlebars to avoid going too
deep).
Best for hilling and furrowing.
Best for making raised beds.
Cultivate (raise handlebars to
avoid going too deep).
Good for tiliing large areas.
Till organic matter in.
Cultivating between raised
beds with hiller-furrower at­
tachment.
FAST GEAR, HIGH BELT RANGE
Prepare seedbeds for planting.
Cover seeds with less need to
hold up the handlebars.
Cultivate (tiller travels faster,
rides higher on the soil; al­
lows engine RPM to be re­
duced; handlebars don’t
have to be raised).
Keep large areas tilled and
cultivated in the summer.
Till under organic matter.
Move tiller location quickly.
Cultivate between raised beds
using the hiller/furrower.
