This is a concept drawing illustrates the
left side of the Dickinson Research Extension Center Cross-Slot™ low-disturbance no-till drill. This drawing and the next two drawings were used by the
engineers to develop the final design of the drill. The final design
was drawn using an autocad program by Steffes Corporation engineers. See the
It was important the frame fit the
openers. This concept drawing shows the
placement of the openers on the tool bars as well as important hydraulic components
necessary for proper opener performance.
This drawing provides the general
dimensions of the frame in the top view.
No-till drill, some assembly
Dean Kovash, project engineer, and Larry
Kostelecky, primary fabricator, discuss drill assembly.
Caster wheels with the rated capacity of
4,400 pounds per assembly are added to the frame. Openers are mounted to the frame. The drive wheel frame (red) extends from the
tool bar to the floor.
The Hege cones were built in Colwich,
Kansas and shipped to Dickinson where they were mounted on the drill
frame. Jack shafts are located and welded
to the frame.
Fabricators, Lyle Mayer (left) and Larry
Kostelecky weld up frame for mounting one of two operators’ seats. The bulk seed and dry fertilizer boxes were salvaged
from a Melroe 202 drill.
Liquid tank frames are added along with
platforms for bulk seed and fertilizer box access.
Adding the finishing touches. Larry Kostelecky adds the extruded metal
floor to the drill. These panels are
easily removed for easy access to interior areas of the drill. After all
parts were fitted and mounted on the drill, all parts are removed from
the drill prior to painting the frame.
The frame has been painted and now
openers, tanks, drop tubes, etc. are ready to be mounted.
The drill is complete and ready for
This picture shows the right side of the
drill. The openers have fertilizer
tubes for both liquid and dry fertilizer.
Major components of the hydraulic system
for DREC no-till drill. Though the drill
is pulled on the lower two links of the three point hitch, the hitch remains level
and the openers move up and down on their own.
The accumulators, shown in the upper left photo, equalize the pressure
within the system. The memory valves
show in the lower right picture allow the openers to be lifted out of the soil
at the end of a pass and then when the openers are set back into the soil this
valve “dumps” the pressure of the system back into the openers so the pressure
is the same as in the previous pass. A
load cell, not pictured, located on the center opener detects the degree of
penetration the opener is experiencing.
A meter in the cab of the tractor provides information to the operator
the amount of hydraulic pressure in the system as well as on the load
cell. The operator can make adjustments
or a computer can do this automatically.
The control panel for the solenoids on
the two Hege frames. The cones on each
frame are timed to open at the correct starting point in the plot.
CDS John Blue single piston pump (in
center of picture) is located on the underside of the frame near the drive
wheel. The hydraulic ram visible in
this picture raises and lowers the drive wheel as well as providing the down
force on the drive wheel which prevents slipage. The drive wheel is plumped into the same
hydraulic manifold as the openers.
Pattison Even-Flo manifold system for the
liquid fertilizer system is attached to the frame member on the left. ZeroMax variable speed transmissions are used
with the seed and dry fertilizer metering systems.
Dr. John Baker, agricultural engineer,
explains how the blades on a Cross-Slot™
opener works at the Direct Seeding Seminar-Options and Issues program at Dickinson, ND November 24 and
25, 2003. Dr. Baker spent 30 years with Massey University researching
and developing no-till equipment prior to founding Baker No-Tillage Ltd.
The Cross-Slot™ opener was developed based on research Baker directed at Massey University. Baker is now CEO of Baker No-Tillage Ltd, Feilding, New Zealand. A video tape of the presentations made during the Direct
Seeding Seminar is available by contacting
the Dickinson Research Extension Center.
