FOREWORD
You’ve just joined an exclusive but rapidly
growing club.
For our part, we want to welcome you to the
group and thank you for buying a Yetter product.
We hope your new Yetter implement will help you
achieve both increased productivity and
increased efficiency so that you may generate
more profit. This operator’s manual has been
designed into six major sections.
Foreword, Safety Precautions, assembly
instructions, Operation, parts identification and
troubleshooting.
It is important the owner/operator knows the
implement model number and serial number.
Write the serial and model number in the space
provided and use it in all correspondence when
referring to the implement.
Throughout the manual references may be made
to left side and right side. These terms are used
as viewed from the operator’s seat facing the
front of the tractor.
This SAFETY ALERT SYMBOL indicates
important safety messages in the manual.
When you see this symbol, be alert to the
possibility of PERSONAL INJURY and carefully
read the message that follows.

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 those working with you and for you follow them.
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.
WARNING
Never clean, lubricate or adjust a machine that is in motion. Always install the transport lock pins and bracket when
transporting for any length of time or on public roadways.
If required to service unit in raised position, be sure to install all transport lock pins and locking bracket.
Be sure the implement is securely locked in the 3-point quick hitch before operating.
Do not allow children to operate this equipment.
Do not allow riders on the tractor or implement.
Use speeds and caution dictated by the terrain being traversed. Do not operate on any slope steep enough to cause
tipping or loss of control.
Be sure all personnel are clear of the immediate area before operating.
Read and understand the operator’s manual and require all other persons who will operate the equipment to do the
same.
In operating on public roadways, where legal, be certain all lighting is operating properly and observe all traffic laws.
Ensure slow moving vehicle emblem on tractor is visible.
Beware of increased stopping distances and control effort when operating with implements attached.
Be familiar with all tractor and implement controls and be prepared to stop engine and implements quickly in an
emergency.
FAILURE TO HEED MAY RESULT IN PERSONAL INJURY OR DEATH

HYDRAULIC ASSEMBLY
ASSEMBLE HINGE LEVERS AS FOLLOWS
1. Drive a 3/8” x 2-1/2” roll pin into one end of each of 4 hinge pins.
2. On one wing of hoe assemble 1” washer on hinge pin, push pin thru near hole in hinge,
insert hinge lever, push pin thru other hole in hinge, assemble another 1” washer and roll
pin.
3. On other end of hinge lever assemble a 1” washer on hinge pin, put thru a wheel, push
rod clevis of a hydraulic cylinder, hinge lever, other side of clevis, wheel, washer, and
secure with another 3/8” roll pin.
4. On the butt end of cylinder remove 1 hairpin clip and the clevis pin, extend the cylinder
and fasten to the cylinder bracket with the clevis pin and the hairpin clip. Check spacing
between hinge lever and hinge bushing; (opposite zerk) and set to 1/8” to 3/16” spacing
by removing clevis pin and turning cylinder into or out of the rod end clevis. Tighten
clevis-clamping bolt.
5. Repeat 2, 3, and 4 for the remaining wing.
6. Lubricate the o-ring on each of the restricted 90-degree fittings and install into the cylinder
ports. DO NOT OVER TIGHTEN AND DISTORT THE METAL BACK-UP WASHER.
Position the fitting by turning it out (counter clockwise) to a maximum of one complete
turn and tighten the jam-nut.
7. There are four hose sizes as follows:
1. ¼” hose (short) 1 pc.
2. ¼” hose (medium) 2 pcs.
3. ¼” hose (long) 1 pc.
4. 3/8” hose, 2 pcs.
8. Connect a short and medium hose on opposite arms of a “T” fitting.
9. Connect a medium and long hose on opposite arms of a second “T”.
10. Position the short hose assembly on the toolbar with “T” on the operators left of the hitch
assembly, position the long hose assembly in the same manner, connect short hose ends
to the inner ports, the longer assembly to outer ports.
11. Connect the 4ft. 3/8” hoses to the remaining “T” ports and tighten ALL connections.
Adapters are provided for the hoses to connect to standard ¾-16 straight thread quick
coupler tips such as Case-IH part no. 1285718* or Deere part no. AR945222.
12. Using the cable ties furnished, tie the outer port hoses to the lower ends of each cylinder
and the hose to the toolbar on each side of the “T”s and at 2 to 3 foot intervals between.
13. IMPORTANT: Be sure to cycle the hydraulic cylinders before attaching them to the
folding wings. This removes air from the hoses and insures smooth wing operation.
CAUTION
STAND CLEAR OF FOLDING WINGS!

ASSEMBLY
SCREEN ASSEMBLY
1. Assemble the screen brackets to the screen with four 3/8 x 1” bolts, lock washers,
and nuts.
2. Mount the screen assembly to the main frame as shown with two u-bolts, lock
washers, and nuts. Additional screens can be ordered if desired.
CAUTION: DO NOT OPERATE ROTARY HOE UNLESS SCREEN IS
SECURED AND PROPERLY INSTALLED.
SMV ASSEMBLY
1. Mount SMV emblem as shown with point of triangle up as near operators left of
center as possible. Face so emblem is visible from rear of equipment.
12
ASSEMBLY
GAUGE WHEELS
Frame gauge wheels maintain the rotary hoe frame at a constant level in respect to the
ground contour, which helps insure uniform penetration of the hoe wheels. Recommended
tire size 7.50 x 14 or equivalent.
Mount the frame gauge wheels as shown, location each wheel an equal distance from the
center of the main frame. Gauge wheels should run outside the tractor wheel tracks.
To tighten wheel bearing, remove the hubcap and cotter pin. Tighten the slotted nut until
there is a slight drag on the bearing, while turning the wheel. Then loosen or back off the
slotted nut one slot and insert the cotter pin. There should be a slight drag on the bearing
following adjustment. Reinstall the hubcap.
CAUTION: ON 3500 MODELS, BEFORE ACTIVATING FOLDING HINGE
CHECK FOR OBSTRUCTIONS, ESPECIALLY CHECK GAUGE WHEEL
POSITIONS TO BE SURE THAT GAUGE WHEELS ARE SET TO CLEAR
TRACTOR AND OPERATOR.
CAUTION: CLEAR ALL PERSONNEL FROM AREA BEFORE FOLDING
OR UN-FOLDING TOOLBAR.
13
OPERATION
ROTARY HOE PREPARATION
BOLTS AND NUTS:
Before starting to work, check all nuts and bolts for tightness.
HOE WHEELS:
Check all hoe wheels for straightness. Replace if necessary.
NOTE: ¼” of “RUNOUT” is acceptable.
LUBRICATION:
The basic Rotary Hoe requires no lubrication. If your hoe is equipped with gauge
wheels, repack the wheel bearings once a year with multi purpose lithium base
grease. On transport, axle straps need to be greased. Hinges on folding hoes
should be greased regularly.
TRACTOR PREPARATION
WHEEL SPACING:
Set the tractor wheels for the desired row spacing so the wheels are centered
between the rows. The distance from center of tractor to the center of the tire should
be the same on each side. Refer to your tractor operator’s manual for correct
inflation and ballast information of the tractor.
SWAY BLOCKS:
Place the sway blocks in the wide setting during transport to prevent any swaying of
the hoe.
DRAWBAR POSITION:
Place the drawbar in the short, center position to provide maximum clearance
between rear of drawbar and rotary hoe.
LIFT LINKS:
Adjust the length of lift links to maximum length. Refer to Tractor Operator’s Manual.
Keep an adequate distance between the tractor tires and rotary hoe toolbar.
If your hoe is equipped with gauge wheels, adjust the lift link pins to allow lateral float.
If gauge wheels are not used, adjust prevent any lateral float movement.
14
ATTACHING ROTARY HOE TO TRACTOR
HITCH ASSEMBLY
The rotary hoe is shipped with mast and hitch pin bushings assembled for CAT III or IV hitches.
Remove bushings as required of your tractor.
Place sleeves and spacers in position to fit your hitch. The lower hitch plates are adjustable to fit your
tractor’s spacing.
CAUTION: BEFORE ATTACHING ROTARY HOE TO TRACTOR, BE
SURE HITCH PINS ARE COMPLETELY ASSEMBLED TO MATCH YOUR
TRACTOR HITCH.
TRACTOR WITHOUT QUICK COUPLER:
Attach rotary hoe to tractor with draft links to lower hitches.
Adjust the center link or extend the draft links to make hookup easier. Raise parking stand and place
in upper position.
TRACTOR WITH QUICK COUPLER:
Lower the 3-point hitch so the upper jaw of the Quick Coupler passes under the
spacer between the hoe mast plates. This allows lower jaws to pass under the hoe
hitch pins. Back tractor up until coupler jaws are under their respective pins and raise
hitch.
CAUTION: MAKE CERTAIN THAT CENTER LINK AND QUICK COUPLER
ARE LOCKED AND LOCK PINS ARE PROPERLY INSTALLED BEFORE
MOVING ROTARY HOE.
15
FIELD OPERATION
PRE-OPERATION CHECK LIST:
Use this checklist each time you operate the hoe in the field. It will help you obtain
satisfactory field operation quickly.
1. Tractor sway blocks in upper position.
2. Center link adjusted for level frame in field operation.
3. Tractor lift links set in lateral float.
4. Tractor rockshaft control lever set in “zero”
5. Check hoe for loose or missing parts. Tighten hardware where necessary.
6. Bent hoe teeth straightened or replaced.
7. Hitch pins fastened and correct spacers used.
8. Quick couplers locked.
9. Adequate ballast added to front of tractor.
IMPORTANT: NEVER BACK UP WITH ROTARY HOE IN THE GROUND.
NEVER TURN WITH THE HOE IN ITS DOWN POSITION.
OPERATING SPEED:
An operating speed of 5 to 8 mph will normally provide the best results. Higher speeds
tend to increase the teeth penetration.
MAIN FRAME HEIGHT:
The mainframe height during field operation will normally be about 22 inches to bottom of
frame.
Without gauge wheels, set the tractor rockshaft control lever to obtain the desired frame
height.
With frame gauge wheels, put the rockshaft control lever all the way forward to lock “it” in
the float position, which will enable the frame gauge wheels to maintain the frame at a
uniform height from the ground.
LEVELING MAIN FRAME
Adjust lift links and center link as necessary to make hoe level and perpendicular to the
ground.
Before activating/folding hinge check for obstructions, especially check gauge wheel
positions to ascertain proper tractor and cab clearance.
NOTE: If gauge wheels are to be used, make leveling adjustments after gauge wheels
are installed.
16

certain operating conditions the Yetter
Wing Lock Kit will hold the wings in
horizontal position when desired. To
allow the wings to float, simply retract
the wing lift cylinders slightly. This
allows complete operator control from
the tractor seat to let the wings float up
or to lock them down.
INSTALLATION:
1. Remove hinge levers and replace
with 4100-205 hinge lever on 41’
hoes unless hinge levers have a
21/32” dia. hole added to mount
wing lock hooks.
2. Drill (2) 17/32” dia. holes (as shown)
in hinge wheel ramp on each side of
toolbar. (Holes are in strap after
3/1/82 mfg.)
3. Mount wing lock guides and wing
lock tabs (as shown) with ½-13 x 11/2” hex head cap screws, lock
washers, and nuts.

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.
Thank you.
