First Time Field Adjustments
When the Terra Max is taken to the field for the first time and
is unfolded, pre-leveling completed, and ready to run, there are
multiple settings that need to be completed to achieve the
desired tillage results.
These settings need to be optimized for best outcome.
These key settings are:
•
Gang Angle
•
Depth
•
Wing Down Pressure
•
Fore and Aft Leveling
•
Finishing Reel Down Pressure
•
Operating speed
All of these settings are important and changing one could
affect others as they are intertwined.
Gang Angle
11. The recommended first step is to set your gang angle,
(Red Handles) by presetting this first time at 3º-4º. This
can later be adjusted in both directions to change results.

Research has shown that 3º-5º of gang angle is the
most popular setting.
12. The terra max may be operated with the gangs running
from 0-8 degrees. Changing this angle does affect the
operation of the unit in a couple of ways. As indicated
above, if the blades are operated at an angle, down
pressure is generally unnecessary. Also, operating speeds
will need to be less when operating with the blades angled
3-6 degrees. Operating speeds should be from 7-9 mph
when operating gangs in the angled position and from 8-
10 mph when operating in the straight position.
13. When operating the terra max with the blades running at
an angle, it is generally unnecessary to operate with
hydraulic down pressure to the wings. Only in very hard
ground will down pressure be needed. If down pressure is
needed, see “ Hydraulic Down Pressure ” on page 19 for
initial setup, If no down pressure is needed, set the fold
hydraulic system to the “FLOAT” position at this time.
14. When operating the blades in the straight position, down
pressure may be necessary, usually between 200 and 400
psi.

Never leave tractor valve centered when unfolded
with machine in motion. Machine damage may occur
when wings flex. The hydraulic down pressure
cylinders have no wing flex capability and oil flow is
required when the wings flex up or down. You must
have the tractor fold hydraulic lever in continuous
downward flow or “FLOAT” position before the wings
can flex over terrain in the raised or lower lift position.
