A PRODUCT OF POST HOLE DIGGER SERIES 903 MOTOR COMPANY ASSEMBLY AND OPERATING INSTRUCTIONS GENERAL The Series 903 Ford Post Hole Digger is designed for use with Ford and Fordson Tractors. It mounts on the tractor lower links and the hydraulic lift rocker as shown in Figure 2. The digger is operated from the tractor seat and is driven by the tractor P.T.O. at the 540 rpm speed only. Maximum digging depth of all Ford Augers is approxi- mately 42 inches, making it ideal for digging fence post holes and for use in construction work to dig holes for pilings or footings. Augers are sold separately, and are available in a wide variety of sizes (diameter) as detailed on page 4- All augers are 42 inches long and are provided with either a plain or serrated cutting edge. This manual contains information pertaining to the assembly, lubrication, and operation of the Series 903 Post Hole Digger. Read it carefully before attempting to assemble or operate the digger. SHIPPING INFORMATION The Ford Post Hole Digger is shipped in one Bundle, No. 22-63.

Item No. Figure No Description 1 1 Universal Drive Shaft 2 1 Frame 3 1 A & Manual 4 1 Gear Housing 5 1 Centering Lever & Control Handle 6 1 Pin 7 1 Lifting Link ASSEMBLY PROCEDURE 1. Secure the lifting link (12), Figure 2, to the frame with the long pin (6), Figure 1, and cotter pins. Make certain that the control handle attaching ears are slanting forward. NOTE: The forward set of holes (A), Figure 2, in the frame is used for row crop tractors, while the rear set of holes (B), is used for general purpose tractors. 2. Disconnect the gear box from the frame by re- moving the long pin (2), Figure 2. Attach the centering lever (3), to the top of the gear box with the two bolts provided on the gear box. Realign the gear box with the frame and install the pin (2), as shown in Figure 2. 3. Secure the control handle (1), Figure 2, between and lifting link ears (5), with the drilled pin and cotter pin provided. ATTACHING PROCEDURE Ford and Fordson Dexta Tractors 1. Attach the lifting link pins (10), Figure 2, to the tractor lower links and secure with linch pins. 2. Attach the frame ball socket assembly (9), Figure 2, to the tractor rocker assembly with the pin and linch pin provided on the tractor. The lower hole in the rocker will give the most ground clearance. 3. Fit the auger (7), Figure 2, on the drive spindle and secure with the 7/16" x 4" hex head shear bolt (6), lock washer, and nut provided. 4. Extend the universal drive shaft (11), Figure 2, and coat it with grease, then slide it back in the drive tube. 5. Disengage the tractor P.T.O. and remove the P.T.O. cap. Turn the P.T.O. shaft manually until the hole is aligned with the spring loaded joint on the universal drive shaft and slide the drive shaft over the P.T.O. shaft until the pin is locked. NOTE: The universal drive shaft on the Ford Post Hole Digger is designed for use on tractors having a P.T.O. drive shaft of 1-3/8" diameter. Tractors having a P.T.O. drive shaft of 1-1/8" diameter must be adapted for use by installing a P.T.O. Coupling Adapter, Part No. 231082. Secure the coupling with a 5/16" x 2-1/4" bolt.

Part Number Description 44746-S8 221799 NCA-22218-A 100918 111856 Washer Spacer, Lower Link Pin Spacer, Upper Link Pin Pin, Drilled Pin, Self-Locking NOTE: Assemble the Ford Post Hole Digger in the same manner as outlined for Ford Tractors, with the lift link in the rear holes (B), of the frame support (13), Figure 2. 1. Adjust the tractor hydraulic lift leveling rods to a length of 24 inches to obtain auger tip ground clearance of approximately 10 inches. 2. On F.M.D. and F.P.M. Tractors, set the tractor leveling rods in telescoping position by reposi- tioning the leveling rod sleeve pin EIADKN- 995250. 3. Place the leveling rod clevises in the forward hole in the tractor lower link assemblies. 4. Lengthen the check chain linkage to permit closing the tractor lower links to a minimum of 26-7/8". NOTE: Remove the Buffer Bar, ElADKN-995309, on Fordson Tractors equipped with an. automatic clutch release prior to post hole digger instal- lation. 5. Position one spacer, Part No. 221799, in each of the ball sockets of the tractor lower links, then insert the post hole digger lifting link pins through the spacers and secure with linch pins. 6. Position an NCA-22218-A Spacer in each side of the tractor upper link support bracket, then attach the frame ball socket assembly to the clevis. Insert the pin, Part No. 100918, through the spacers and the front link and secure with the self-locking internal hair pin, Part No. 111856. To complete the installation procedure, follow steps 3, 4, and 5, under Ford Tractors. LUBRICATION There are three lubrication fittings on the Ford Post Hole Digger. One fitting is provided on each uni- versal shaft joint and one on the shaft tube. Lubri- cate these fittings with a good grade of grease after assembly and every eight hours of operation thereafter, or more often if required. The gear box is shipped less oil and should be filled with 2 quarts of SAE 90 EP oil. To fill the gear box, remove filler plug (4), Figure 2, pour 2 quarts of Figure 2 Post Hole Digger Assembled on Tractor SAE 90 EP oil into box. Install the filler plug. Remove plug (8), to check the lubricant level occasionally and keep the gear box two-thirds full. OPERATION The Ford Post Hole Digger is easily operated from the tractor seat by means of the tractor hydraulic system and the manual centering lever. Drive the tractor into position with the auger directly over the center of the hole location and set the engine P.T.O. speed according to ground conditions. CAUTION: The 1000 rpm range on Select-O-Speed equipped tractors should never be used to drive the Post Hole Digger. Make certain the hydraulic system is in Implement Position Control. Engage the P.T.O. and lower the digger until the auger point and cutting edges engage the ground. In order to drill a clean hole, drill in a foot or so then raise the auger until it is almost out of the hole. Then, drill deeper and repeat this pro- cess until the desired hole depth is reached. The Ford Post Hole Digger operates equally well on either hillside or level land. The auger unit is sus- pended so that it is free to swing toward or away from the tractor. The centering lever, which is easily reached from the tractor seat, centers the auger for vertical drilling. The adjustment provided by the tractor lower link leveling crank compensates for the tractor tilt. When operating on level ground or ground of uniform slope, drill the first hole to the desired depth and then set the stop on the hydraulic lift control quad- rant so the lever will be moved downward the same distance in drilling each successive hole. On uneven ground or slopes it will be necessary to vary the hydraulic quadrant setting to maintain consistent hole depth. The condition and type of soil and the experience of the operator will determine the engine rpm for the most efficient digging. When digging hard ground, serrated cutting edges should be used. IMPORTANT: In the event that the auger shear bolt (6), Figure 2, breaks due to an obstruction in digging, replace only with special Shear Bolt, Part No. 107328. CAUTION: Always make certain that the P.T.O. is disengaged before leaving the tractor seat.
