FIELD OPERATION
ROTARY SEPARATOR SPEED -- Figures 53 and 54
The rotary separator is driven by pulley V which has a
double groove for an alternative speed:
S 760 rpm is the factory-set speed which is suit-
able for most crops such as barley, oats, rye,
wheat, rice, grass seed, etc.
S 400 rpm is for harvesting maize, beans, peas,
soya, sunflower, oil seed rape, etc.
To change the speed, proceed as follows:
1. Move lever A out of hook B and upwards.
This will move the idler C downwards and loosen
the belt tension.
2. Install the belt in the other grooves of both pulleys.
3. Move lever A downwards and secure the lever in
hook B as shown.
4. Check the belt tension and adjust, if necessary
(refer to Section 5 - ADJUSTMENTS AND MAIN-
TENANCE,
paragraph
chains'').
The rotary separator is accessible through the cover
which is situated underneath the grain tank.
CONCAVE POSITION
Refer to paragraph headed ''Multi-thresh system''.
The function of the Straw Flow beater L is to improve
the combine throughput capacity in specific condi-
tions (heavy green, damp straw).
On combines equipped with a Straw Flow beater L
and operating in severe crop conditions (very dry or
brittle), the rotary separator M, and so the Straw Flow
beater L, can be set on low rpm speed (400 rpm) if the
straw breaks up too easily.
