The Yetter Electric Air Compressor assembly builds 145psi of air pressure and dispenses that air to the row cleaners' air bags as
the operator commands it from the tractor cab. Yetter electric compressors are durably constructed and designed for easy
integration to operate the Yetter 2940 Air Adjust System. The ability of the air adjustments allows the operator to adjust the row
cleaner precisely on the move without leaving the tractor cab resulting in more acres planted. The precise adjustments give the row
units and planter a more even, smoother ride leading to more accurate seed placement and seed depth resulting in a more uniform
emergence. IT IS NOT RECOMMENDED TO PLUMB ANY OTHER PNUEMATICALLY OPERATED SYSTEMS TO USE THE
2940 YETTER ELECTRIC COMPRESSOR AS ITS AIR SOURCE.
POWER SUPPLY
The compressor and the VDM (Valve Drive Module) each use 12V from the battery.
The 2940-100 Cab Controller uses a switched power source. The 2940-153 will need connected to a switched power source.
(Connector to the tractor not included)
A CIGARETTE LIGHTER OUTLET ISN'T A SWITCHED POWER SOURCE AND THEREFORE SHOULD NOT BE USED.
SWITCHED POWER SOURCE CONNECTOR PART #'S:
JOHN DEERE P/N: RE67013

FUSE PROTECTION
To protect the compressor assembly & VDM from damage always ensure the integrity of the integrated 40 amp and 80 amp circuit
breaker at the tractor battery where cable connects to the battery in case of short or over-circuit. When connected correctly, the
tractor has a fuse to protect the cab controller located in the tractor's fuse panel. NEVER MOUNT THE COMPRESSOR
ASSEMBLY MORE THAN 50 FEET FROM THE BATTERY USING THE PROVIDED MAIN POWER CABLES. THIS WILL
WEAKEN THE 80AMP BREAKER TO THE POINT OF FAILURE. IF MORE THAN 50 FEET IS NEEDED, BUILD POWER
CABLE(S) TO LENGTH USING 00 GAUGE CABLE!
AIR COMPRESSOR MAINTENANCE
To prolong life expectancy of the compressor, clean the filter on a regular basis by removing the element from the housing, tapping
it on a hard surface, exposed side down. This will empty the pleats of the filter of collected dust. If the dust has been wet or will not
clean out, call Yetter to order a new element, part number 2940-395. You may lightly blow out the interior of the upper housing
using an air tool. The housing and filter should be checked every two days of field operation, or more if conditions are very dusty.
See pages 45 for further maintenance.
CONNECTIONS
FAILURE TO LINE UP TABS WHEN PLUGGING MALE INTO FEMALE CONNECTORS CAN RESULT IN SHORT CIRCUIT.
ALSO CHECK TAB AND SLOT SIZES, PLUGGING CONNECTORS IN BACKWARDS WILL RESULT IN FAULTY SYSTEM!!
