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.

ASSEMBLY INSTRUCTIONS
GENERAL INFORMATION
Examine all equipment carefully for damage or shortages.
Lubricate all bearings and moving parts as assembled.
Reference to front, rear, left and right in this installation instruction are made when setting in the operator’s seat
facing direction of forward travel.
BOLT TORQUE
READ THESE INSTRUCTIONS FIRST:
1. Improperly tightened bolts will result in damage, breakage, expense, and down time.
2. Always replace bolts with the specified grade and type.
3. Torque properly before first use of the machine and every 2-4 hours of use until you are sure bolts are
staying tight.
4. The chart below is a guide for proper torque. Use it unless a specified torque is called out elsewhere in the
manual.
5. Torque is the force you apply to the wrench handle or the cheater bar, times the length of the handle or bar.
6. Use a torque wrench whenever possible.
The following table shows torque in ft. lbs.

5
ASSEMBLY INSTRUCTIONS
WARNING: Never work under the equipment while in a raised position without using safety
lockups. Failure to do so may lead to personal injury.
Transport Wheels
STEP 1. The carts are shipped with only the inside wheels assembled. Attach the outside wheel and hub
assemblies 6600-146 by inserting the spindle shaft into the tube welded to the bottom of the lift wheel insert using 1)
½” x 3” hex bolt and ½” hex lock nut.
STEP 2. Check the air pressure in the four tires; the pressure must be EQUAL to each other (36 psi cold). If the tire
air pressures are not equal when operated, the upper and lower rollers will wear and fail to operate, causing damage
to the lift wheel insert.

6
ASSEMBLY INSTRUCTIONS
Hanger Bar
STEP 1. Attach the hanger bar assembly to the 8” x 8” center frame using the 4) 1” x 11” hex bolts and 1” hex lock
nuts. The right rear bolt is also used to attach the toolbar depth indicator 6300-347. Position the assembly on the
center frame with 6300-212 toolbar flange plate w.a. hook over the drawbar flange plate. Torque the 1” bolts to 670
ft. lbs.
STEP 2. Attach the toolbar depth gauge to the rear of the toolbar using 1) ¾” x 5” x 6-1/2” u-bolt, 6300-348 strap,
and ¾” lock nuts. Locate the depth gauge up to the right hand side of the center frame.

7
ASSEMBLY INSTRUCTIONS
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.

ASSEMBLY INSTRUCTIONS
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.

10
ASSEMBLY INSTRUCTIONS
STEP 7. Mount a set of clamp plates to the toolbar at each chalk mark using 4) ½” x 8” bolts, 2) shank clamp
castings, and ½” lock nuts.
For crop residue flow through the coulter, it is best to mount the coulters alternating to the front and to the backside of
the toolbar.
NOTE: It is very important; before tightening the bolts, that the clamp plates be square to the toolbar.

11
ASSEMBLY INSTRUCTIONS
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.

12
ASSEMBLY INSTRUCTIONS
STEP 10. Slide the shank up through the clamp castings and retain by installing a 5/16” x 2 ½” cotter pin in the top
hole of the shank. Allow the shank to hang on the cotter pin and triple tighten the 5/8” x 1” square head set screw
into each clamp casting.
STEP 11. Install the blade to the coulter hub using 4) ½” x 1 ½” carriage bolts, ½” lock washers and ½” hex nuts.
Rotate the blades checking for wobble and clearance. If blade wobble is excessive, check for burrs on hub mounting
surface or loose bearings. Correct the problem and recheck for wobble in the blade.
IMPORTANT: CHECK ALIGNMENT OF DRILL OPENERS TO COULTERS IN THE FIELD BEFORE
PROCEEDING TO PLANT SEED. MINOR CORRECTIONS TO ALIGNMENT CAN BE MADE BY ROTATING THE
OFFSET SHANKS, LARGE ADJUSTMENTS REQUIRE MOVING THE CLAMP KIT ON THE TOOLBAR.

13
ASSEMBLY INSTRUCTIONS

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.
Hydraulic Hook Up
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 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.
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.

17
OPERATION
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 CASE-IH 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.

18
OPERATION
MARKER HYDRAULICS
Row marker may be plumbed into the cart transport lift system.
STEP 1. Plumb the “LIFT/RAISE” hydraulic hose of the marker system to the top end of the left cart cylinder (4 x 20).
STEP 2. Plumb the “DROP/LOWER” hydraulic hose of the marker system to the bottom end of the right cart cylinder
(3 ¾ x 20).
NOTE: After purging the hydraulic system of air. Check the adjustment and operation of transport wheel rollers.
These rollers must turn when the cart is raised and lowered. Inspect and lubricate the upper and lower rollers daily.

19
OPERATION
ATTACHING IMPLEMENT
WARNING: Be sure the attached implement is securely locked in the hitch of the cart before
operating. Failure to heed may result in personal injury or death.
WARNING: Always install the transport lock pins when transporting at any time. 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.
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: Do not allow children to operate this equipment. Do not allow riders on the 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.
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.
