INSTALLING 2940 AIR COMPRESSOR ASSEMBLY
Step 1: Every planter/tractor combination will contain its own unique situations in regard to mounting the 2940
Compressor Assembly for clearance and accessibility. YOU SHOULD EXERCISE YOUR OWN BEST JUDGEMENT TO
FIT YOUR SITUATION. Begin by locating a suitable mounting location for the compressor assembly. Placement of the
compressor assembly will vary on the make and model of the planter. Use mounts supplied or depending on
application different mounts may need to be built. NOTE: Be sure to check clearance of compressor assembly in all
locations, especially noting tractor tires and folding/unfolding the planter for transport mode, markers, and 2-point top link.
Step 2: Visually inspect the proposed mounting location for structural stability and to find signs of wear in that location.
Possible obstructions to be aware of include marker arms, liquid fertilizer tanks, rear tires (duals especially) during tight
turns, 2 point top link, etc...
Step 3: Mark out the position of the Compressor then complete a cycle of folding/unfolding to transport mode and
raising/lowering of the planter; as well as, driving in a tight circle in one or both directions, in planting position, to verify or
identify obstructions.
Step 4: Once the compressor is mounted, repeat the previous process very cautiously to once again verify that the
compressor is clear of obstructions.
Always mount the compressor in the vertical position, housing above the tank.
2940-085 – Mounting Kit is designed for mounting to
the 2 point cross hitch on the planter, or areas that
require higher elevation for clearance. Different size
bolts may be needed.
2940-090 & 2940-091 – Mounting Kits are designed
to mount the compressor on the main tongue in front
of the bulk fill tanks. 2940-090 is for 8 X 12 frames &
2940-091 is for 8 X 16 frames. These will not work if
fertilizer tanks are mounted in these locations.
In some situations, mounting brackets may need to be built to fit your planters set-up.
Refer to pages 60 for Part Identification.
2940-086 – The most common mounting location for larger
planters will be on the draft bar. Use the 2940-086 mounting kit
for situations that require mounting elsewhere on the planter
than the hitch. This will allow the compressor to be elevated &
offset to avoid clearance issues. Different size bolts may be
needed.
