SubTiller II
Fall Till Point
The fall till point is designed to fracture
compacted soil when operated at a
depth of 14” to 18” deep. Ideally the point
of the shoe should be run 1” to 2” below
the compacted “zone” which generally
will be found at the 8”-14” depth. Do
not run the SubTiller II point too deep.
This may result in wasted horsepower
and a slicing effect through the hardpan
rather than a lifting and shattering effect
directly under the compacted zone.
Summer Till Poin
t
The summer till point is designed to
penetrate the soil for air filtration and
water penetration combined with a slight
fracturing effect. It is ideally suited
for pivot irrigated crops and also may
be used successfully on dry land row
crops, pasture and hay land.
By penetrating soil from 10” to 14” the
summer till point is most effective. If
the soil appears to be lifting the dry
land row crop excessively it may be
advisable to quit. In extremely hard soil
when weather conditions are hot and
dry, the summer till point may injure
roots structures, especially when water
cannot immediately be applied.
Shanks
Replace the Shear bolt on the standard
shank model only with 3/4” x 4 1/2” grade
2 bolts. Use of grade 8 or harder bolts
will void the warranty of the machine. Do
not attempt to hard surface the SubTiller
II summer till or fall till points. These cast
items have undergone a special heat
treating process that will be modified
if additional heat is encountered.
