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.

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.
