SET-UP INSTRUCTIONS
NOTE: For ease of assembly, if header is still in
shipping position install wheel supports and
springs before lowering header to field position.
Take care not to damage components when
header is lowered. These instructions assume
the header is already lowered to field position.
1. Use a lifting vehicle to raise rear of header,
or attach header to windrower or combine
and raise header fully.
DANGER: To avoid bodily injury or
death from unexpected start-up or
fall of raised header, stop engine,
remove key and engage header lift
cylinder stops before going under
header for any reason. If using a
lifting vehicle, be sure header is
secure before proceeding.
2. Identify right and left wheel supports. Left
wheel support has dual spindle.
3. Ensure plastic bushings (A) are installed (2
per support). Position wheel assembly in
header leg and install tube (B) from right
side of header leg through wheel support.
Secure with two 5/8 x 1-1/4” carriage bolts
(heads outboard) and flange nuts.
IMPORTANT: If wheels are required for
transport only and will not be used in field mode
to assist header floatation or to stabilize sway,
installation of springs is not required. Leaving
the springs off makes putting the wheels into
and out of transport position easier, however
springs are required if used for floatation in field
mode. See “Raising Wheels to Storage
Position”, page 21.
4. Attach
springs:
With 872 Combine Adapter or Windrower
Tractor: For 30’ single sickle header
install two springs at left side of header,
one spring at right side. For 30’ double
sickle or 36’ headers, install two at both
sides (an extra spring is provided with these
headers).
With 873 Combine Adapter: Install one
spring at each side.
L/H Wheel Support: Engage spring hooks in
anchor (C) at wheel support, then attach
front end of springs to header leg with pin
(D). Secure with cotter pins.
NOTE: Tube (B) is designed to be a press-fit
into leg. Use a hammer or the hardware to fully
engage tube into leg (with flange on tube flush to
leg).
