MacDon 9200 - Header Angle

OPERATION
Header Angle
Header angle is adjustable by changing the length
of the center link between header and tractor.
Header angle adjustment
ranges :
910,920 , 932 Headers: 8" to 16 °
942 Header: 6
0
to 13 °
960,962 Header: 13° to 21"
972 Header: 9.5
0
to 21°
NOTE: Above figures are guard angle in degrees
below horizontal.
IMPORTANT: A flatter header angle is recom-
mended for normal conditions. A flatter angle
reduces sickle section breakage and reduces so il
build-up at the cutterbar
in wet conditions.
Use a steeper angle to cut very close to the
ground, or for better lifting action of down crops.
To adjust header angle:
1. Unlock collar (C) by tapping it in a counter-
clockwise direction.
2. Using a long punch in hole (0), turn the center
link
until the desired header angle is reached.
Shortening the link will give a flatter header
angle, while lengthening the link provides
steeper angles.
3.
Lock collar (C) against link body by tapping in a
clockwi
se direction to secure the position.
To adjust header
angle when cutting on the ground:
HEADER ANGLE ADJUSTMENT
When cutting with header on the ground, the header height switch can be used to adjust header angle "on the
go". Familiarize yourself with how the header reacts during this adjustment to take full advantage of the
feature.
1. Lower header by pressing bottom of header height switch until cutterbar just touches ground. At this po i nt,
cutterbar is at the flattest guard angle.
2. If a steeper angle is de s ired, continue press i ng bottom of switch. This will steepen the guard ang!e until lift
cylinders are
fully retracted.
3. To ad j ust angle from steeper to flatter, press the top of the header height switch to extend cylinders a small
amount. Once the flattest angle is reached, further activating the switch will lift the cutterbar off the ground.
Use this adjustment in combination with the center link adjustment (above) to achieve the desired range
through which the header angle moves before header lifts off the ground.
See "Header Controls" in Operator's Station section for use of header height switch and cut height indicator
with regard to header angle.
