Before beginning, raise machine up in air at a sufficient
angle so springs are relaxed with no tension remaining
on the parallel arms. Support with stands.
Crushing Hazard:
Do not work around heavy equipment without support stands
appropriate to the amount of weight they must bear.
1. Remove clamp at base of hose on the old hopper.
This releases the hopper and all parts above
2
hose as one unit. Discard all parts, they will not
be reused.
2. Disconnect the air inlet hose from the seed meter by
removing its clamp (see photo below). Save the
clamp for later assembly.
3. If a blockage monitor is present, disconnect the wire
leading to it by removing the zip tie holding it in
place. (Do this at the same time as disconnecting
the other hoses.)
4. Remove hex nut and 65⁄8inch bolt , also remove
hex nut , washer and 4 inch bolt .
This releases the hopper support weldment and
RH and LH hopper braces and from the
opener arm.
