SET-UP INSTRUCTIONS NOTE: For ease of assembly, if header is still in

shipping position insta ll wh eel suppor ts 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 bush ings (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 us ed 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 f ield mode. See “Raising Wheels to Storage Position”, page 21.

4. Attach springs:

With 872 Combine Adapter or W indrower 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 spri ng is prov ided with thes e headers).

With 873 Combine Adapter spring at each side.

L/H Wheel Support anchor (C) at wheel support, then attach front end of springs to header leg with pin (D). Secure with cotter pins.

: Engage spring hook s in

: Install one

NOTE: Tube (B) is designed to be a press-fit

into leg. Use a hamm er or the hardware to fully engage tube into leg (with flange on tube flush to leg).

5. R/H Wheel Support:

a. Engage spring hook(s) in anchor at wheel

support same as L/H side shown in Step 4. Attach front end of spring(s) and trans-axle assembly to header R/H leg as follows:

NOTE: The trans-axle can be installed on inboard or outboard side of leg for 972 or 973 headers, but must be outboard on 974 Headers. This determines the side of the leg where the trans-axle wheel will be placed in storage. For headers with R/H decks that can be split for end delivery, choose the side that places the working wheel away from the windrow delivery opening.

IMPORTANT: For 973/974 headers, spacer (E) for transaxle is not used. Install 33mm ID x 57mm OD flat washer provided in kit instead. For both inboard (973) and outboard (973/974) installations, position washer on outside of leg with one cotter pin inside leg and one outside.

For installation outboard of header leg - 972:

b. Knuckle (A) must be tight against face of header

leg when trans-axle is mounted on outboard side of header leg.

For installation inboard of header leg – 972: d. Space knuckle away from leg as at (D) when

installing on inboard side of header leg.

VIEW FROM REAR OF HEADER – INBOARD SIDE

- INBOARD INSTALLATION – 972 ONLY

e. Install spacer (E) against inside face of header

leg to maintain knuckle spacing away from other face of header leg. Install cotter pin (G).

c. Install cotter pin (B) through second hole from

end of pivot shaft and through spacer to hold knuckle against other face of header leg. Store second cotter pin (C) in outer hole of pivot shaft. NOTE: Assembly of knuckle away from face of leg will result in excessive “toe-in” of R/H wheel located underneath cutterbar.

6. Install trans-axle storage latch at right header leg. Install on same side of leg as trans-axle. See Step

5. Engage top leg of torsion spring on edge of header leg as shown.

NOTE: Step 7 is for 972 and 973 Headers only – Not required for 974 Header.

7. Install anchor (G) for diagonal brace under cutter bar.

For trans-axle positioned inboard of R/H leg: Install

anchor at 14

guard bolt inboard

of center of R/H header leg.

For trans-axle positioned outboard of R/H leg: Install

anchor at 10

guard bolt inboard

of center of R/H header leg.

NOTE: For applications where the sickle guards are in stalled above the cutterbar, install

anchor spacer (H) and special hardware as shown. For applications where guards are below cutterbar, use 7/16 x 2 ¼ hex head bolt (head down) and locknut. Spacer (H) and special hardware are not used with guards below cutterbar.

9. At L/H support, install upper pin (A) in desired stubble height position and secure with split ring. When header is lowered, spring-loaded brack et will engage upper pin as shown below.

Push down on handle (B) and lock under welded bolt head to raise pin (C) to allow wheel to pivot. Pivot whee l to field position. Release handle (B) fr om under bolt head to lower pin (C) and lock in field position.

10. At R/H support, install upper pin (D) in desired stubble height position and secure with split ring. When header is lowered, spring-loaded brack et will engag e upper pin .

Push down on handle (F) and lock under welded bolt head to raise pin (G) to allow wheel to pivot. Pivot wheel to desired field position. Releas e handle (F) from under bolt head to lower pin (G) and lock in field position.

NOTE: Wheel can be positioned on either side of support, depending on delivery opening position. (See Step 5.)

R/H WHEEL SUPPORT: FIELD POSITION NOTE: Install the two decals provided on the inboard face of left and right frame legs as shown below. The decals indicate proper pin position for storage, different levels of stubble height, and transport.
