IMPORTANT: The gear box is shipped without lubricant. Fill the top hole with EP 90 lubricant or the
equivalent. The gear box holds 25 oz. (0.7 liter). Fill to the bottom of the plug hole on the side.
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 provided with the gear box. When
in place secure with cotter pins provided. 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 2 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 2
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 (13D) 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:
Check all nuts and bolts for tightness. Stabilizers should be kept tight to avoid side sway of the
digger.
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 A.
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.
