Operating Instructions
Before beginning work:
• Be sure all the seed cups completely close and open the same, so all cups are putting out the exact amount
of seed. If they are not in sync, one cup will put out more than others.
• Ensure when completely closed, the seeding gears are not protruding from the outside the cup.
• Adjust the clamps to ensure all cups close and open completely and uniformly.
NOT FLUSH—GEARS PROTRUDING FLUSH—GEARS NOT PROTRUDING
The Seed cups on the DRL may come with either of
two different style of seed cups or a combination of
both. Typically the front Seed box section is equipped
with a “LARGE SEED CUP and the rear section typi-
cally has the LEGUME SEED BOX.
To adjust seed output:
The LARGE SEED front section is usually driven with an 11-26 Gear ratio, while the back LEGUME SEED
section is being reduced to put out less with a 12-40 Gear Ratio.

Operating Instructions
Seeding/Fertilizing rate adjustment handle:
To adjust the fertilizer rate, you will need to adjust hand wheels (on each side of hopper). The seed/fertilize
rate depends on the seed/fertilizer you want to plant, please refer to your seed/ fertilizer supplier’s chart to get
the proper seed/fertilize rate.
Before adjusting the seed rate, return the rate on the Scale to zero by rotating the hand wheel, then check and
make sure all seeding/fertilizing wheels are fully closed on all seeding/ fertilizing boxes. (SEE BEFORE BE-
GINNING section) If not, you need to loosen the clips on both sides of the seeding/fertilizing wheel and push
the wheel into the box. Tighten the clips. When the seeding/fertilizing box is closed and the meter indicates
“0”. Adjust fertilizing rate by rotating the hand wheel. The meter has 8 numbers from 0-8, from zero to Maxi-
mum.
Weight, size, relative humidity, and moisture content can affect seeding rates. Users can adjust the position of
the seed/fertilizer “TONGUE” and lock in different positions by moving the cotter pin to meet the different
seeding/fertilizing size. The smaller the seed, the higher up the TONGUE should be positioned. For larger
seed, the “TONGUE” should be opened more.

Seed cup shutoff:
Depending on the crop being planted, it may be necessary to not disburse from all of the seed cups. This is eas-
ily done by simply sliding the “Seed shut off flap” in and out.
Closed
The depth in which the application is done is controlled by adjust-
ing the basket located near of the machine. Adjusting the “Sowing
depth control device “ as follows:
Turning knob clockwise will make the basket drop which in turn
will raise the disc openers and lessen the depth of the application.
Turning the knob counterclockwise would raise the basket which
would lower the disc openers and make the application deeper.
The top link on the tractor should be properly adjusted to carry the
machine level in an operating position. During operation, the tractor
lift must be fully lowered to allow the machine to follow the con-
tour of the ground.
The machine is totally ground driven so proceed with a speed that
is most comfortable and safe for existing conditions. Be sure to stop
forward motion before lifting machine off ground. This practice
will stop rollers from “free spinning” and therefore eliminate the
unwanted application when turning around.
Never operate the machine in reverse.

Lubrication and Maintenance
Important: It is important to thoroughly clean the seeder after use. Failure to do so can cause irreparable dam-
age to the seed cups and drive system. Grease and turn the Seed adjustment handle to ensure grease lubricates
the threads.
There are a few ways to clean out the hoppers:
• Each hopper is equipped with a cleanout spout in the front of each hopper.
• The rear hopper is equipped with a quick release lever located under the center of the hopper. By pulling
down the lever, all the hopper tongues will open and cause the seed/fertilizer to drop out of each of the
seed cups.
• Each seed cup can be emptied individually by pulling the cotter pin on the side of the cup and dropping
down the hopper tongue.
Changing Discs
Important: When replacing the discs, it is extremely important to remember that one of the disc hubs has left
hand threads and the other right hand threads. The threads can be stiped if removed improperly. Left side hub,
turn Clockwise to loosen and turn counter-clockwise to tighten. Right side hub, turn counter-clockwise to loos-
en and clockwise to tighten.
Step 1: Remove the dust cap.
Step 2: Remove the external scraper dust cap.
Step 3: Remove hub nuts.
Step 4: Unscrew the hub from the disc support.
Step 5: Replace the discs and reassemble.
1 Hour Check all fasteners and hardware including set screws in sprockets and bearing collars and re-
tighten as necessary.
8 Hours Grease bearings on roller and apply grease to torsion bar wheel mechanism.
As needed: Remove any crop residue, grasses, weeds, or debris wrapped around shaft discs or rollers. This
can cause bearings to overheat and lead to premature failure.
Always: Protect the machine from weather. NEVER leaver fertilizer in hopper. Do not leave seed in
hopper for more than 24 hours. Remove all fertilizer and seeds from hopper. Thoroughly clean
hoppers and lubricate all drive chains before storage.
Important: When replacing the discs, it is extremely important to remember that
the left disc hub has reverse (LH) threads. The right disc hub has normal (RH)
threads. If turned incorrectly, they can strip.
