Operating Instructions
Prior to Going to the Field
1. Both dealer and customer read and
thoroughly understand all safety
recommendations. (These are found in the
Safety Section of this operator manual.)
2. Make sure your tractor horsepower matches
the implement you are pulling. This is
important so the implement can do the best
possible job.
3. Clean all hydraulic couplings and connect to
tractor or host implement. Each hydraulic
coupling has a colored handle on it and is
marked with a cylinder, either extending or
retracting.
4. After the turbo-till is attached, raise and lower
the turbo-till several times to purge air from
the hydraulic system. Again check for
hydraulic leaks and tighten or replace if
necessary.
5. Check the tire pressure for proper inflation
and check the tightness of the lug bolts. Tire
pressure information can be found in the
Appendix of this manual.
6. Check for any bolts that may need tightened
or retightened. Grease all the hinge points.
The hubs come pre-greased and will not need
more grease at this time.
7. Prior to transporting, fully raise the turbo-till.
Install the transport locks. Always use the
transport locks when moving from field to field
in case of a hydraulic hose failure. You are
now ready to go to the field.
General Operating Instructions and In-Field Adjustments
1. Extend the turbo-till lift cylinders and remove
the transport locks.
2. For an initial starting point, set the pre-load on
the top nut on the reel arm assembly to 1/8”
from the top of the spring bolt to the top of the
3/4” lock nut.
3. Set the pre-load on the eye bolt to 1 1/2” from
the bottom of the eyebolt to the bottom of the
3/4 jam nut, this is also just an initial starting
point
4. You may need to adjust the eyebolt to change
the down pressure. Adjust the bottom 3/4 jam
nut closer to the bottom of the eyebolt for
more down pressure. You may need to adjust
the top lock nut spacing accordingly to raise
reel up for road clearance. Adjust the bottom
3/4 jam nut away from the bottom of the
eyebolt for less down pressure.
