Assembly Instructions for the Ultra-Till
2/26/04
Thank you for purchasing the Great Plains Ultra-Till. To finish assembly you must first mount
the tires to the inside wings. Mount the tires as shown in layout (Inside Wing Wheel Assembly.) The
hub assemblies with the smaller titan tires pre-mounted get pinned on the caster wheel assemblies as
shown in layout (Caster Wheel Assembly – UT5042, UT5048, UT5052 ONLY.)
Then you must locate the correct coulter/disc gang assembly. The assembly should come to you
with a part number written on the gang. Simply match the part number on the gang frame with the
number located on the respective assembly layout and assemble as shown on the coulter/disc gang setup.
The next step is to start assembling the ball joint brackets on the phoenix module, so they can be
hung on the Ultra-Till frame. Assemble ball joint brackets as shown on (Phoenix Module Assembly.)
Leave all the nuts loose so the ball joint bracket can slide on phoenix module. On the end of the phoenix
module there is a number written in white paint. This will assist you in location of these modules.
Simply match the number on the side of the phoenix module to the number given in the respective
layout and assemble accordingly. Once phoenix module is hung tighten nuts on ball joint bracket to the
x dimension given for each individual module. This will place the phoenix modules in the correct
location and alignment. Once this is done, double check the machine with the layouts provided and
make sure there is no interference. This should complete the assembly of your Great Plains Ultra-Till.

UT3030 Ultra Till Hydraulic Down Pressure Preparation and Setup
Note: This setup procedure is for tractors with closed-center or pressure compensated flow
hydraulic systems. For open-center hydraulic systems contact your dealer for instructions.
1. Adjust the bypass/pressure reducing
valve by turning knob (1), Figure 1,
clockwise all the way in and then backing
out 1 full turn.
2. On tractor, adjust flow-control valve to low
side of flow rate. NOTE: The faster the
flow of oil through the system the greater
potential for oil heating, premature wear
or tractor damage.
3. Lock the fold hydraulic lever for
continuous downward oil flow.
4. Adjust bypass/pressure reducing valve
knob (2) on implement so the pressure
gauge reads 1200 psi. Never exceed
1400 psi.
5. While watching pressure gauge, slowly open
valve knob (1) until gauge reads 1100 psi.
Pressure might rise and then fall off as knob
is opened. If pressure exceeds 1400 psi
during this step, the tractor flow is too high,
reduce tractor flow. Lock valve knob (1) at
1100 psi.
6. Finally adjust valve (2) to the desired wing
down pressure setting of 400 to 700 psi.
Never exceed 900 psi.
7. In field operation, Lock the fold
hydraulic lever for continuous
downward oil flow. If wings are
running too high, increase pressure
setting, knob (2), to level machine. If
center is too high, decrease pressure
setting with knob (2) on valve.
