NOTE! This SAFETY ALERT SYMBOL is found throughout this manual. It is used to call attention to instructions involving your personal safety and the safety of others. Failure to follow these instructions can result in INJURY OR DEATH. This symbol means ATTENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED!
SET-UP FOR FIELD OPERATION Your grain cart comes set-up with exception of wheel/tire installation, side extensions, ladder, auger extension chute, electrical hook-up to tractor, and tire pressure check. If your implement dealer has not set up the preceding items, the procedure is simple. SIDE EXTENSION SET-UP Refer to parts page in Section 2 for extension placement.
SET-UP DRIVELINE STORAGE Storage brackets are located on the inside right frame rail. Secure the PTO shaft to these brack- ets for extended transporting or seasonal storage. IMPORTANT: Remove and store the • complete PTO before towing grain cart behind a delivery truck.
ELECTRICAL HOOK-UP Your Grain Cart is supplied with a seven-point SAE connector plug which will adapt to the receptacle found on several new tractors on the market today. If not available, an SAE J S60A seven-point outlet socket can be purchased from your Unverferth dealer (order Part #92824).
DUAL WHEELS SPINDLE 1. If necessary, replace existing wheel studs with longer 3/4-16 UNF x 3 1/2" studs. INSIDE DUAL WHEEL: 2. Install inside dual wheel. 3. Use 3/4-16 hex jam nuts (27/64" Thick) on small holes. 4. Tighten the five jam nuts to 200 Ft. Lbs. OUTSIDE DUAL WHEEL: 5.
TRACTOR HOOK-UP Make sure sufficient counter-weight is used on the tractor's front-end. Move draw bar into closest position for even terrain. Make sure draw bar length and PTO telescoping limits are adequate for • uneven terrain, gullies, rice levees etc. Never exceed the maximum recommended hitch pin size which allows for uneven terrain.
AUGER FOLD ADJUSTMENT The auger fold linkage is adjusted at the factory and under normal operating conditions should not require adjustment. Disassembly for service or slight wear in the linkage pins may necessitate the need for adjustment. The 1/8" compression dimension is necessary for a good seal at the auger flanges and snap locking at the end of the cylinder stroke.
HYDRAULIC AUGER OPERATION For PTO & DIRECT DRIVE Applications Initial start-up: Flow Door is to be closed. With flow door closed, engage hydraulic motor with maximum oil flow from tractor. NOTE: Free running auger oil pressure will range 500 PSI or less. The pressure gauge will register system work load as flow door is opened.
ADJUSTABLE UNLOADING CHUTE (OPTIONAL) INSTALLATION: 250957 1. Remove existing chute. 2. Fold overlap and snap four end snaps. 3. Slide chute over outlet shroud with overlap towards hitch. 4. Install top and bottom strips over chute and fasten with existing capscrews, flatwashers and locknuts.

LUBRICATION AND MAINTENANCE To keep your grain cart in top operating condition and to assure its proper performance and reliability for a long period of time, a periodic inspection and lubrication is a must. The lubrication locations and recommended schedule are as follows: A.
ADJUSTABLE AXLE - MODELS 672, 674 ADJUSTABLE AXLE (120" - 154") Raise center axle weldment. Loosen clamp plate capscrews on slotted slides of axle weldment Extend axle to desired width and align holes for studs if greater than 144". Remove axle stud and spacer pipe from storage brackets on rear of axle. Install in outer set of holes for desired axle width.
PTO SHAFT & CLUTCH To avoid injury do not clean, adjust, unclog, or This Safety Alert Symbol means Attention! service PTO driven equipment when the tractor en- Become Alert! Your safety is involved! gine is running. Never exceed the recommended operating speed for the particular equipment in use.
D. Lubrication (Figs. D1 - D6) Lubricate with quality grease before starting work and every 8 operating hours. Clean and grease PTO drive shaft before each prolonged period of non-use. Molded nipples on the shield near each shield bearing are intended as grease fittings and should be lubricated every 8 hours of operation! Telescoping members must have lubrication to operate successfully regardless of whether a grease fitting is provided for that purpose! Telescoping members...
G. Chains (Figs. G1 - G3) NOTE: The chain is intended to prevent the shield from rotating against non-moving parts and thereby preventing shield damage. A properly installed chain will increase the service life of the shield. 1. Chains must be fitted so as to allow sufficient articulation of the shaft in all working positions.
K. To assemble guard: (Figs. K1 - K5) 1. Grease yoke groove and inner profile tube. 2. Fit bearing ring in groove with recesses facing profile tube. 3. Slip on half-guard. 4. Turn cone until it engaes correctly. 5. Install locking screw. 250968K L.
QUICK DISCONNECT PIN Quick-disconnect P i n Compression Spring Washer Using a drift punch and hammer, drive the pin towards the retaining washer to force the complete assembly out. Clear the edges of the retaining washer bore to accept the new one by removing the deformed metal from the last peening operation to hold the washer in place.
