9.0 CLEANING
Cleaning is an important part of harvester maintenance. This section illustrates a few locations
where mud will routinely build up and need to be cleaned.
9.1 Row Finder
Row finder wands (A) and springs (B) must be
cleaned routinely in order for the row finder to cor-
rectly locate beets.
Also, clean the area around the hydraulic valve spool
and all other moving components to prevent seal
failure.
9.2 Lifter Struts and Paddles
Lifter struts and paddles typically require the most fre-
quent cleanings. Any mud buildup around the lifter
struts and paddles must be periodically removed for
optimum performance and to prolong machine life.
IMPORTANT: If left unclean, mud buildup in these are-
as may lead to paddle shaft failure, slip clutch failure,
excessive paddle wear, lifter strut seal damage, and/or
lifter strut bearing failure.
9.3 Grabrolls
Mud buildup on grabrolls can typically be eliminated by
proper drive sheave selection. If increasing grabroll RPM
does not eliminate mud buildup, clean the grabrolls pe-
riodically until conditions improve.
