ASSEMBLY INSTRUCTIONS
Read the complete assembly instructions before starting the assembly.
You should have:
- one tillage tool assembly
- one lift control wiring assembly
- five 9” cultivator sweeps with five bevel washer spacers
A. ASSEMBLY OF TONGUE
CAUTION: Steps 1 and 2 should be performed with caution. Care should be taken to prevent back injuries or other lifting related injuries.
- The crated tillage tool should have arrived in a vertical position. Lay the crate down with the tires positioned towards the ground. Remove the crate and position the tillage tool on it’s side. Remove the center coulter assembly by removing the wire lock pin. At this time the tongue can be rotated in a counter-clockwise direction towards the front of the tillage tool assembly. Reinstall the center coulter assembly and fasten securely with the wire lock pin that was previously removed. (See Figure 1.)
- Position the tillage tool assembly upright on the tires.
- Measure the hitch height on your tow vehicle. For hitch heights of 11” or less use the lower tongue mounting holes. For hitch heights of greater than 11” use the upper tongue mounting holes. (See Figure 2.) The factory tongue setting is in the lower position. To reposition the tongue remove the provided 5/8” x 2” bolts, lock washers and nuts, align proper holes and reinstall and secure the bolts, lock washers and nuts.
- Remove the provided 3/4” x 3 bolt , lock washer, and nut from the loose end of the top link. Align the top link with the free arm on the tongue. Install and securely fasten the bolt, lock washer and nut that was previously removed.
INSTALLATION OF THE LIFT CONTROL WIRING ASSEMBL Y
-
Using the provided “U” bolts, securely fasten the lift control panel to the tow vehicle. On most ATVs, the “U” bolts will allow easy installation on the rack.
-
There are two separate electrical cables extending from the lift control panel. There should be a cable that contains battery clips and another cable that has a connector attached to the end. Attach the connector side to the actuator connector. Attach the battery clips to the appropriate terminals on a battery (red attaches to the positive terminal and black to the negative terminal).
Note : Extra electrical cable length can be purchased (Extension Cable Part #235067) if needed. In some applications it may be necessary to have extra length to reach the battery or reposition the lift control panel. -
Securely fasten the electrical cable that extends back to the actuator. Using the provided plastic ties, fasten the cable to the tongue and tow vehicle. Position the disconnect plug such that it can be easily disconnected when the tillage tool is removed from the rear of the tow vehicle.

A. INTENDED USE
This tillage tool is intended for use behind an ATV, UTV (utility vehicle / side-by-side) or small sub-compact tractor to till various types of ground and prepare a seedbed. -
B. LEVELING THE TOOL
This tool is equipped with a leveling device to adjust for different hitch heights as well as to make the tool level. When adjusted properly, the tool will stay relatively level throughout the height adjustment range.
Note: When leveled, the tool will operate more efficiently in the ground. An unleveled tool can result in improper coulter or sweep function.- Remove the hitch pin from the tongue and attach the tongue to the hitch on the tow vehicle.
- This leveling can be done by adjusting the top link. Unlock the locking tab on the top link.
Turning the handle on the top link counter-clockwise will raise the rear end of the tool and clock-wise will lower the rear end of the tool. After adjustments are made, lock the top link in place. (See Figure 2.)
Note: Depending on ground conditions, slight adjustments may need to be made after the tool
-
C. COULTER FUNCTION
This model is equipped with five separate coulters. The coulters serve as cutting blades and are meant for light debris cutting, ground scoring for better ground shatter and aiding in reducing clod size. If the debris is not cut the shanks tend to collect debris and act as a rake. This in turn will prevent normal operation. In many cases 150-300lbs of added weight is very effective in helping the coulters to penetrate. If the coulters do not penetrate, then the coulters will not function as effectively. It may take slight leveling adjustments with the top link to provide good coulter penetration as well as sweep depth. -
D. SELECTING THE PROPER SWEEP – Refer to Figure 3.
This tool is equipped with two types of sweeps, reversible chisel point sweeps and 9” field cultivator sweeps. Selecting the proper sweep is critical in helping the tool to perform correctly.
The reversible chisel point sweeps are a good choice in hard ground conditions. These sweeps have the ability to easily penetrate and shatter hard ground conditions.
The 9” field cultivator sweeps are typically used for secondary tillage and are a good selection to use after initially breaking hard ground with the chisel point sweeps. The field cultivator sweeps also work well in shearing off weeds. In softer ground conditions, these sweeps can be used for primary tillage. A bevel washer spacer is also provided with these sweeps. This spacer will tip the sweep and provide a steeper more aggressive angle of attack. These washers should only be mounted on the top holes of the sweeps and placed between the shank and the sweep.
Note: An optional turning shovel kit can be purchased (Part # 003801). These sweeps are a good choice when working in sod conditions. In hard ground conditions it may be necessary to install the provided bevel washer spacers. These spacers will place the shovels at a steeper more aggressive angle of attack. These washers should only be mounted on the top holes of the shovels and placed between the shank and the shovel.
- E. ADJUSTING THE SHANKS AND COULTER SHANKS – Refer to Figure 4.
The shanks and coulter shanks have been designed for quick adjustments. Both removal or maximum depth adjust changes can be made very quickly. The shanks can be set at a maximum depth of 2”, 4” or 6” with the tool fully lowered. The coulter shanks can be set at a maximum depth of 2”, 3” or 4” with the tool fully lowered. In many cases the tool will function better if the sweeps are set several inches deeper than the coulters.
Note: It is important to re-install the coulter shanks on the proper side of the shank receiver.
- F. SUGGESTIONS FOR PROPER OPERATION
Proper tool adjustment can increase functionality and efficiency.
Hard Ground
In hard ground conditions, the reversible point chisel sweeps should be
installed. The reversible point chisel sweeps have the ability to penetrate
hard ground fairly effortlessly without added weight. Additional weight is
recommended to help the coulters penetrate. This tillage tool has been
equipped with weight racks. These weight racks will easily allow for several
hundred pounds to be added to the tool. Depending on what depth the coulters
are set at, it is very important to achieve coulter penetration. If the
coulters do not penetrate this will be limiting the sweep depth. In these
cases it is recommended to raise the coulters to the highest setting or remove
them. Removing the coulters or limiting the coulter depth may create a problem
in heavy debris conditions. In these conditions it may work best to remove the
middle shanks to allow for debris clearing.
Heavy Debris Covered Ground
It is recommended these conditions be mowed first if possible to help chop up
the debris. In heavy debris covered conditions, additional weight is
recommended to help the coulters penetrate and cut debris. This tillage tool
has been equipped with weight racks. These weight racks will easily allow for
several hundred pounds to be added to the tool. In certain cases if the debris
is too heavy, the coulters may not work even with added weight. In these cases
it may be necessary to remove the two middle shanks on the rear of the tool.
This will allow the debris to clear the tool with limited collection. Removal
or fully raising the middle two coulters will also be necessary to help place
more weight on the remaining coulters. (See Figure 5.)
Sod Covered Ground
It is recommended that these conditions be mowed and sprayed with a grass
killer. A grass killer will not only kill the green growth but will help to
break up the root structure as well. Sod is also easier to work with in the
spring or shortly after a rain. In some soft ground or limited sod conditions,
it may be possible to use the 9” field cultivator sweeps or reversible point
chisel sweeps. In most cases the optional turning shovel kit will work best
(Part # 003801). The turning shovels have the ability to strip the sod off and
roll it to the side to prevent collecting on the shanks. In hard ground
conditions it may be necessary to install the provided bevel washer spacers
shown in Figure 3. These spacers will place the shovels at a steeper more
aggressive angle of attack. In all cases additional weight is very helpful to
maintain coulter penetration. The coulters will cut the sod which helps
prevent collection on the shanks and reduces the pulling load requirements. In
heavy sod conditions it may work best to only use two turning shovels. If only
two turning shovels are used place the shovels on the shanks closest to the
center of the tool.
(See Figure 6.)
Rock Covered Ground
In most cases reversible point chisel sweeps will have the best chance of
working in heavily rock covered ground on the initial pass. These sweeps will
provide the least resistance. It may be necessary to raise or remove the
coulters. If the coulters are being forced out of the ground due to rocks, it
may be difficult to get adequate sweep penetration. Raising or removing the
coulters can also help prevent damage to the coulter blades when striking
large rocks.
Soft Ground Conditions or Previously Tilled Ground
Soft ground conditions can be performed with any of the sweeps. The 9”
field cultivator sweeps tend to work the best in these cases. These sweeps
will help to fully shear the ground off and create a true seedbed. The
optional drag harrow kit (Part # 003800) can be added as well for these
conditions. The drag harrow will help to level the ground and reduce clod
size. If there is limited debris, the coulters can be removed. With the
coulters removed the two center sweeps can be moved forward. (See Figure 7.)
