OPERATION
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 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.
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. 16).
FIG. 15
ADJUST WHEELS FOR CULTIVATING (See
Figs. 16 and 17)
• Place blocks under right hand side of tiller and remove
hairpin clip and clevis pin from right hand wheel.
• Move wheel outward approximately 1 inch (2.5 cm)
until hole in inner wheel hub lines up with inner hole
in axle.
• Replace clevis pin and hairpin clip on inside of wheel
and remove blocks.
• Repeat preceding steps on left hand side.
NOTE; In extremely rough conditions and while cultivat­
ing, the wheels should be moved outward on the axle for
increased stability.
