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.
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 &

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
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.
