SAFETY PRECAUTIONS
You can make your farm a safer place to live and work if you observe the safety precautions given. Study
these precautions carefully and insist that they be followed by those working with you and for you.
Finally, remember this: an accident is usually caused by someone’s carelessness, neglect or oversight.
DANGER
Inspect and replace worn or frayed hydraulic hose, keep all connections tight. Escaping hydraulic fluid
under pressure can have sufficient force to penetrate the skin and cause serious personal injury. Fluid
escaping from a small hole can be almost invisible. Use a piece of cardboard or wood rather than the
hands to search for suspected leaks.
CAUTION
Consult your implement and tractor operator’s manual for correct and safe operating practices. Be aware of
towed implement width and allow safe clearance.
CAUTION: SAFETY SIGNS
Safety decals are placed on the implement to alert the operator and others to the risk of personal injury or
unsafe operation during normal operations and servicing.
1. The safety decals must be kept clean and in good condition to ensure that they are legible.
2. Safety decals must be replaced if they are missing or illegible.
3. When components are replaced during repair or servicing, check that the new components include
the necessary safety signs.
4. Replacement safety decals may be obtained from your local Yetter dealer.

Attaching the 5” x 5” coulter toolbar to the hanger bar
STEP 3. A coulter will be mounted on the cart directly in line with each opener on the implement that will be
mounted on the cart. Most implements have an even number of openers with no opener in the center,
measure the length of the 5” x 5” toolbar and mark the centerline.
STEP 4. Align the center of the coulter toolbar with the center of the frame. Attach the 5” x 5” toolbar to the
rear of the hanger bar using the offset brackets, ¾” u-bolts, and ¾” lock nuts. Rigidly fasten one bracket
between the toolbar with the rear u-bolt on the center line (on even number of coulters) of the coulter
toolbar. Assemble the four remaining brackets to the toolbar; refer to the illustration below. The location of
the bracket is determined by the width of the toolbar and the row spacing of the implement.

STEP 5. Attach the 2) 6300-207 cylinder lugs to the coulter toolbar using ¾” u-bolts and ¾” lock nuts.
Locate the inside edge of the cylinder lug 21 ¾” from the centerline of the coulter toolbar.
Clamp Kits: Even number of openers
STEP 6A. Determine the location on the 5” x 5” toolbar. If your implement has an even number of
openers, divide the row width by two and chalk mark that distance for the first coulter on each side of the
centerline. Now mark the rest of the toolbar for the coulter location, measuring from the two center coulters.
See example of even number of openers on 10” spacing.
Clamp Kits: Odd number of openers
STEP 6B. Determine the location on the 5” x 5” toolbar. If your implement has an odd number of openers,
start on the centerline of the toolbar and measure each way the distance of the row spacing and mark the
location of each coulter. See example of odd number of openers on 15” spacing.

STEP 8. Insert the locking collar into the pivot casting of the coulter assembly. Slide the shorter offset end
of the shank down through the assembly and drive the 3/8” x 2 ½” roll pin through the bottom hole of the
shank for a retainer.
NOTE: For additional clearance for and aft of the coulter blades, assemble half of the coulters with the
lower portion of the offset shank forward (to be mounted on the front of the toolbar) and assemble the
remaining coulters with the offset shank backward (to be mounted on the rear of the toolbar).
STEP 9. Screw the 5/8” x 1” square head set screw into the locking collar; triple tighten (tighten, loosen,
tighten, loosen, tighten) to 100 ft. lbs. max. torque. The locking collar should carry the weight of the coulter
instead of the roll pin.
Note: Do not allow the roll pin to set into the notch of the pivot casting since that will lock the coulter from
swiveling.

OPERATION
PREPARING THE TOOLBAR
Drawbar Height
The Yetter model 6300 coulter cart is designed to operate on tractors with drawbar heights from 18” to 22”
from the ground to the top of the drawbar. On certain tractors the drawbar can be turned over to obtain the
correct height.

and cause serious personal injury. Fluid escaping from a small hole can be almost invisible. Use a
piece of cardboard or wood rather than hands to search for suspected leaks. Failure to heed may
result in personal injury or death.
The Yetter coulter cart requires two remote hydraulic valves on the tractor for proper operation. Before
operating in the field, perform the following steps.
DANGER:
tight, escaping hydraulic fluid under pressure can have sufficient force to penetrate the skin
1. Connect the Yetter cart to the tractor drawbar before operating the cart hydraulic system. Check
the tractor hydraulic system fluid level. Filling all four cylinders with fluid will require approximately
2 ½ gallons. DO NOT operate tractor hydraulics when fluid level is too low.
2. Disconnect rear lift cylinder rod-end pins when the weight is relieved from the cylinders. Space the
cylinder away from the frame by placing 4” wide blocks between the cylinder and frame to allow the
rods to extend freely.
Inspect and replace worn or frayed hydraulic hose. Keep all connections

Hydraulic Hook Up Continued
3. Connect the two hoses from the transport lift system to the tractor. The hydraulic hoses are
provided with the adapter attached. Use ¾-16” standard thread quick coupler tips such as CASEIH part no. 1285718C or DEERE part no. AR94522.
4. Extend cylinder slowly while watching to see that the rod ends do not hit any obstruction. Because
these are re-phasing cylinders, the left cylinder will extend first and then the right.
5. Hold hydraulic lever in extend position for 15 seconds after cylinders are fully extended to purge air
from the system.
6. Recheck tractors fluid level and refill if necessary.
7. Cycle cylinders back and forth a couple of times to see that they operate together. Hold the lever in
the extended position a few seconds after each cycle for additional air purging.
8. Retract the cylinders and reconnect rod-end pins and hairpins.
9. Raise lift cylinders and install transport lock pins in lower set of holes in the vertical tubes for
transport. Store pins in the upper set of holes during operation.
10. Repeat steps 1-9 to purge air from the coulter toolbar lift cylinders.
NOTE: After purging the hydraulic system, check adjustment and operation of transport wheel rollers.
These rollers must turn when the cart is lowered or raised. Adjust the rollers as necessary.

WARNING:
Failure to heed may result in personal injury or death.
The Yetter coulter cart is designed for use with 3 point mounted grain drills, planters and other integral /
mounted implements.
The implement must be equipped with a category II or III spreader bar with category II spread or the
implement must have a category II hitch.
STEP 1. Carefully back the Yetter cart to the implement. Raise or lower the cart to align the hitch of the
cart with the pins of the implement.
STEP 2. Secure the hitch locks with the 6300-102 pins and 7 ga. hairpins. Connect the adjustable top link
of the cart to the lower hole in the center anchor of the implement. Lock the jam nut when the leveling
adjustments are completed.
Be sure the attached implement is securely locked in the hitch of the cart
Always install the transport lock pins when transporting at any time.
Proper operation of the implement requires the frame to be level from front to rear as well as side-to-side.
Refer to the manufactures of the implement’s operation manual for more instructions. During field
operation, the toolbar frame height must be controlled by the position of the drive/gauge wheels of the drill.
Always fully lower the cart and retract the lift wheels when seeding/planting.
IMPORTANT: Check clearance of the implement and the cart transport tires. A quick hitch may be
required when using certain implements to space implement from tires.
IMPORTANT: Yetter carts used with subsoilers/rippers are not to be used where rocks or other
obstructions are present and are subject to the following limitations; subsoiler no larger than 5
shanks, tractor not to exceed 280 flywheel horsepower.

OPERATION
FIELD OPERATION
WARNING:
tractor. Failure to heed may result in personal injury or death.
Lift cylinders raise the cart. Since the attached implement is a 3-point mounted unit it will raise with
the cart. The cart is lowered when the lift cylinder lifts the transport wheels off the ground. The
wheels of the implement then support the cart.
The toolbar cylinders regulate the depth of the coulters on the cart. A parallel linkage allows
adjustment to the coulter depth without affecting the depth setting of the implement.
The planting depth is controlled by the gauge wheel setting of the implement unit. See owner’s
manual for your implement.
NOTE: In extremely difficult no till conditions such as hard packed soil it may be necessary to fill
the transport tires with fluid to add weight to the rear of the cart forcing the coulters to cut. The
spring adjustment nut on the coulters can also be tightened. Also, an optional weight kit 6300-129
(10 suitcase weight capacity) is available.
IMPORTANT: Do not adjust the coulter depth so deep that the coulter hubs are running in the soil.
This will cause premature bearing failure.
Do not allow children to operate this equipment. Do not allow riders on the
COULTER ADJUSTMENTS
COULTER SPRING TENSION
Spring tension is set at the factory with ¾” locknut flush with the end of the spring rod. In hard or dry
conditions additional spring pressure may be attained by tightening the locknut down a maximum of ½”.
COULTER BLADE TRACKING
Minor adjustments to align the coulter blades with the attached implement can be made by loosening the
set bolt in the shank clamps and rotating the offset shanks to align the coulter with the opener on the drill.
IMPORTANT: Do not adjust the coulter depth so deep that the coulter hubs are running in the soil,
this will cause premature bearing failure. See coulter operation manual for further information.

DOWN PRESSURE REGULATING VALVE KIT
The down-pressure regulating valve kit replaces the two “T” fittings, in the middle of the cart, joining
together hoses from the toolbar cylinders.
1
NOTE: This down-pressure regulating valve kit is for use with tractors with closed center hydraulics only.
NOTE: MUST have gauge wheels on toolbar.
NOTE: This hydraulic system does not compensate for conditions varying from soft to hard as you travel
through the field.
When adjusting active hydraulic down-pressure it is important to remember the following:
IMPORTANT: Excessive down-pressure can increase wear, increase draft loads, decrease effective seed
depth and reduce gauge wheel bearing life. Use only as much pressure as necessary to achieve
consistent operating depth.
CAUTION: DO NOT ride on machine to adjust down-pressure or you could
fall off and be run over resulting in severe injury or death.
- Seed depth is largely controlled by coulter depth when using a coulter cart.
- The active hydraulic down-pressure system keeps the toolbar gauge wheels in contact with the soil
surface as the ground contour changes.
- The amount of down-pressure required depends upon soil hardness, moisture and residue cover.
- The recommended initial setting is between 400 and 600 psi.

Our name
Is getting known
Just a few years ago, Yetter products were sold primarily to the
Midwest only. Then we embarked on a program of expansion and
moved into the East, the South, the West and now north into Canada.
We’re even getting orders from as far away as Australia and Africa.
So, when you buy Yetter products . . .you’re buying a name that’s
recognized. A name that’s known and respected. A name that’s
become a part of American agriculture and has become synonymous
with quality and satisfaction in the field of conservation tillage.
