IMPORTANT:The gear box is shipped without lubricant. Fill the top hole with 80W - 90WT lubricant or the
equivalent. Approximately1.75 quartsof the lubricantis enough tolubricate the gears and
bearings. Agreater amount will not harm the gear box. Do not fill to overflow point as this may
damagethe seals.
NOTE: Orderpart number 00724177 for 1 quart of 80W - 90WT gearoil.
STEP 1: Becertain that thegear box hasadequate lubrication. Checkthe oil levelafter 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
lynchpin (not provided) through the swivel ball at the bottom of the boom.The ball accepts
either category 1 or 2 pins.
STEP 3: Connect the “A” frame (5) to the tractor’s 3-point lift arms using the 7/8 in. hitch pins with nut
and lockwasher (7) as shown in the drawing.Attach the “A” frame (5) to the boom (1) after
selecting the desired hole (for angle adjustment) using the Toplink pin (6) and lynch pin (4).
STEP 4: Attach the gear box (10) to the boom (1) using the boom pin (2) supplied with the gear box.
When in place secure with the cotter pins (3) provided.
NOTE: Input shaft shield (9) and output shaft shield (8) are already attached to the gear box.
STEP 5: Attach the auger to the output shaft on the bottom of the gear box (10) using the 1/2 in. hex cap
screws (15), 1/2 in. lockwashers (16) and 1/2 in. hex nuts (17). Tighten thenuts.
STEP 6: Attach the driveline (11) to the gear box input shaft using the 3/8 in.grade 5 hex cap screw (12),
the 3/8 in.lockwasher (13) and the 3/8 in. NC hex nut (14). Tighten the hex nut. Insert the 1/4
in. x 3/8 in. set screw (22) in the hole on the yoke that aligns with the 3/16 in. groove onthe gear
box input shaft. Tighten loosely.

STEP 7: Attach the tractor end of the driveline (11) to the tractor PTO shaft. Slide the collar away from the
tractor, slide the yoke onto the PTO shaft of the tractor. Release the collar. 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 illustrationA for reference in assembling the digger and mounting it to the tractor. Note that
theboom anglecan beadjusted onyour tractorfor properdigging and ground clearance by
movingthe “A” frame to a different mounting holeas shown in illustration B.
NOTE: When the 7/8 in. diameter hitch pins in the “A” frame are too small for the holes in the lift arms,
bushings should be used to obtain a proper fit.
