Soil Compaction
Soil Compaction is the compression of
soil particles from excessive weight on
moist soils. Ideal soil conditions for best
Sub-Tilling results are when the soil is
dry. The dryness of the soil is directly
related to the amount of fracturing that
can be accomplished with the BLU-JET
SubTiller II. Positive results have been
documented after sub-tilling in wet
conditions, however, the probability of
greatest response is when the soil is
dry. Do not run livestock on sub-tilled
soils until the ground has frozen and
remove them before thawing to avoid
compaction. Avoid operating tillage
tools on wet sub-tilled fields. Compaction
can easily reoccur.
3-Point Installation
Measure tractor linkages on pull arms to
insure equal length for level operation
as viewed across the rear of the tractor.
Check tractor tire pressure for equal
inflation. Install SubTiller frame onto
the tractor. Be certain that the proper
pins are used in either CAT. II or CAT. III
hookup.
SubTiller Operation Instructions
Soil surface disturbance may be modi
-
fied by using the third link adjustment.
The SubTiller will normally be operated
in a “level” tool bar position or slightly
tipped back position. By shortening the
turnbuckle and running at shallower
depths, soil surface disturbance will
be increased. Tractor speed should be
between 4 m.p.h. and 6 m.p.h. for optimum
fracturing effect.
WARNING:
Thurston Manufacturing does not recommend the use of three point SUBTILLER ll
on articulated four wheel drive tractors. Damage to the tractor or SUBTILLER II will not be
covered under warranty. SUBTILLER II used with articulated four wheel drive tractors should
be pull type models.
