IMPORTANT:
The gear box is shipped without lubricant. Fill the top hole with 80W-90 lubricant or the equivalent.
Fill until the lube appears at the side level check hole. Approximately two pints or two pounds of
the lubricant is enough to lubricate the gears and bearings. A greater amount will not harm the
gear box. Do not fill to overflow point as this may damage the seals.
STEP 1:
Be certain that the gear box has adequate lubrication. Check the oil level after every fifty hours
of use.
STEP 2:
Attach the boom (1) to the top link mounting bracket on the tractor using a top link pin and a
lynch pin (not provided) through the hole at the bottom of the boom.
STEP 3:
Connect the “A” frame (5) to the tractor’s 3-point lift arms using the 7/8 in. pull pins with nut and
lockwasher (5A) as shown in the drawing. Attach the “A” frame (5) to the boom (1) after selecting
the desired hole (for angle adjustment) using the “A” frame pin (6) and lynch pin (4).
STEP 4:
Attach the gear box (10) to the boom (1) using the boom pin (2). When in place secure with
cotter pins (3). NOTE: Input shaft shield (9) and output shaft shield (12) are already attached
to the gear box.
STEP 5:
Attach the auger (20, 21 or 22) to the output shaft on the bottom of the gear box (10) using the
1/2 in. hex cap screws (17), 1/2 in. lockwashers (18) and 1/2 in. hex nuts (19). Tighten the nuts.
STEP 6:
Attach the driveline (13) to the gear box input shaft using the 5/16 in. grade 5 hex cap screw (14),
the 5/16 in. lockwasher (15) and the 5/16 in. NC hex nut (16). Tighten the hex nut. Insert the 1/4
in. x 3/8 in. set screw from the hardware kit in the hole on the yoke that aligns with the 3/16 in.
groove on the gear box input shaft. Tighten.
ATTENTION:
THE 5/16 IN. HEX CAP SCREW PROVIDES SHEAR PROTECTION. USE A GRADE 5
2-1/2” BOLT ONLY TO AVOID DAMAGE TO THE GEAR BOX OR AUGER.
IMPORTANT:
The universal joint should be greased with a good grade chassis lube every week. At the
beginning of each season grease the sliding driveshaft members with a moly grease. All
diggers are equipped with quick-detach universal joints on the power-take-off end for a
1-3/8 in. splined shaft.
STEP 7:
Attach the tractor end of the driveline (13) to the tractor PTO shaft. Push in the spring-loaded pin
in the splined yoke (13C) and slip it on the splined PTO shaft of the tractor. Release the pin and
push until it locks securely in place. It will be necessary to obtain a 1-1/8 in. to 1-3/8 in. sleeve
spline adapter if your tractor PTO shaft has a 1-1/8 in. spline.
STEP 8:
Attach and secure both chains on the driveline to the boom (1). See illustration A.
STEP 9:
Attach the handle (8) to the gear box (10) and secure with the 5/16 in. set screw (11). Tighten.
STEP 10:
Check all nuts and bolts for tightness. Stabilizers should be kept tight to avoid side sway of the
digger.

ASSEMBLY INSTRUCTIONS
NOTE:
See illustration A for reference in assembling the digger and mounting it to the tractor.
Note that the boom angle can be adjusted on your tractor for proper digging and ground
clearance by moving the “A” frame to a different mounting hole as shown in illustration B.
NOTE:
When the 7/8 in. diameter pull pins in the “A” frame are too small for the holes in the lift
arms, bushings should be used to obtain a proper fit.
