10 Operating Instructions
These moisture levels can be present at other
times of the year and ripping is not confined to
the end of Spring.
When ripping for other reasons such as
deep working or bed or site preparation, soil
moisture content may not be so critical to a
successful outcome.
10:4:6 Hard ground or ground
which comes up in large clods
Generally, most conditions suitable for
cultivation will allow you to get good
penetration and good results from ripping.
However, sometimes ripping in very dry
conditions may result in large, hard to break
clods and boulders being lifted to the soil
surface.
If this occurs, it is totally unsatisfactory and
you must wait for more suitable moisture
conditions.
10:4:7 Wet Soils
There are limitations to the performance
of any ripping implement especially when
conditons become too wet for good ripping
results.
The Deep Digger is designed to lift and break
or shatter hard layers of sub-soil and for deep
ripping. If conditions are too moist, then the
tine will only slice through the soil and smear
the soil. In this case the soil must be left to dry
out.

10:4:8 Stumps and Rocks
The Deep Digger is capable of pulling out
small stumps such as grape vine butts but
must not be used for large stumps rocks, or
land clearing operations.
WARNING!
Failure to lift the Deep Digger while
turning will cause uneven ridging and
cause unnecessary pressures on the
tines. Failure to lift the Deep Digger
while turning may bend tynes. If the
Deep Digger is used for pulling out
stumps and rocks or land clearing
operations, warranty will not be
covered.
