BOLT TORQUE
Important: Over-tightening hardware can cause just as much damage as under-tightening.
Tightening hardware beyond the recommended range can reduce its shock load capacity.
All hardware is either Grade 5 unless otherwise noted. Grade 5 cap screws are marked with three radial
lines on the head. Grade 8 cap screws are marked with six radial lines on the head. If hardware must be
replaced, be sure to replace it with hardware of equal size, strength and thread type. Refer to the torque
values chart when tightening hardware.
The chart below is a guide for proper torque. Use it unless a specified torque is called out elsewhere in
the manual. Torque is the force applied to the end of the handle or cheater bar, times the length of the
handle or bar. Tightening hardware beyond the recommended range can reduce its shock load capacity.
Use a torque wrench wherever possible
The following table shows torque in ft.-lbs. for coarse thread hardware.

Step 3: Install the fertilizer wheel mount to the main mount bracket using 3) ½ X 2 ¼ bolts, 3) ½ flat washers, & 3) ½ lock nuts.
Install each wheel assembly by placing a 5/8 flat washer over the D-Bolt, slide the D-Bolt through the hole to set the depth
of the blade (see page 16 for depth chart), & install a 5/8 whiz lock nut. Install the injector holder by threading 1) 3/8 jam
nut approximately 2” onto the threads. Place a 3/8 flat washer on the threads & slide the threads through the horizontally
slotted hole. Place a 3/8 flat washer over the threads, followed by a 3/8 lock washer, & thread a 2nd 3/8 nut on the threads.
Adjust the injector holder to be centered behind the blade & fasten in place. Install the male connector on the top of the
injector holder.

- On dual fertilizer placement, the wheels are staggered front to back
to keep the soil from heaving.
- Fertilizer can be placed 2” – 3” off the seed furrow. Please see your
agronomist to determine best spacing on the rate that’s being applied.
- Blade replacement is necessary when the depth cannot be achieved or
the blade struggles to penetrate the ground.
- If there is buildup of damp soil on the planter gauge wheels or opener disks,
then conditions are less than ideal & some problems may also be
encountered with the fertilizer wheel.
- Seed depth will need rechecked after fertilizer unit installation.
- More row unit down force will be needed to maintain fertilizer wheel depth.
STEP 9: Assemble nozzle tip (not supplied) to each 2968-218 injector holder. Injector tips can be ordered through
fertilizer equipment dealer. Calibrate the fertilizer pump and tips to maximum recommended pressure
of 30PSI and minimum 20PSI at the tip. Attach the fertilizer hose to the top side of each coupler.

IMPORTANT: If seal is removed from hub/bearing assembly, grease bearing
Every 50 hours. If seal is left assembled, 2-3 pumps of grease twice a year,
depending on acres, is sufficient.
IMPORTANT: For proper operation, the planter frame must operate level
(fore, aft & side to side) and at the correct height, typically 20”-22”.

Grease must fill this
Hubcap cavity.
NOTE: BE CERTAIN TO ALIGN THE GREASE FITTING WITH THE SLOT IN THE WHEEL & HUBCAP SO THAT THE GREASE
CAN FLOW FREELY.

CAUTION: To help prevent serious injury/death to you or others caused by unexpected movement, service machine
on a level surface. Lower machine to ground or sufficiently lock or block raised machine before servicing.
If machine is connected to tractor, engage parking brake & place transmission in “PARK”, shut off engine,
& remove key. If machine is detached from tractor, block wheels & use shop stands to prevent movement.
CAUTION: DO NOT CLEAN, LUBRICATE, OR ADJUST MACHINE WHILE IN MOTION
Use grease based on NLGI consistency numbers & the expected air temperature range during the service interval.
Use a multi-purpose polyurea, water resistant, moderate speed, & NLGI grade #2 grease. Other greases may be used
if they meet the following NLGI Perfomance.
IMPORTANT: Some types of grease thickener are not compatible with others. Consult your grease supplier before
mixing different types of greases.
Alternative Lubricants
Conditions in certain geographical areas may require special lubricants & lubrication practices which do not appear in
the operator’s manual. If there are any questions, consult Yetter Manufacturing Co. to obtain latest information &
recommendation.
Storing Lubricants
Your machine can operate at top efficiency only if clean lubricants are used. Use clean containers to handle all
lubricants. Store them in an area protected from dust, moisture and other contaminants
LUBRICATION SYMBOLS
Lubricate with grease at hourly interval indicated on symbol if Lubrication Intervals
seal has been removed. If seal is left installed on hub/beairng
assembly, apply 2 – 3 pumps of grease to each hub twice a
season to keep cavity full.
IMPORTANT: The recommended service intervals are based on normal conditions; severe or unusual conditions may
require more frequent lubrication. Perform each lubrication and service procedure at the beginning
& end of each season. Clean grease fittings before using grease gun, to avoid injecting dirt & grit into
the bearing. Replace any lost or broken fittings immediately. If a fitting fails to take grease, remove &
clean thoroughly, replace fitting if necessary. Also check for failure of adjoining parts.
BEARING REPLACEMENT INSTALLATION
1. When assembling the spoke wheels, bearing assembly and hubcap, be sure to align the grease transfer hole
in the spoke wheel with the groove in the hubcap and hole in the hub to allow grease passage.
2. Assemble the wheels, hubs and caps.
3. Grease the wheel/hub/bearing assembly.
