GENERAL SAFETY AND PREPARA TION
ALWAYS make sure that anyone else who operates this post hole digger has read and understood the contents of the
owner’s manual and all safety decals on the product.
ALWAYS be certain that all members of the work party are familiar with the operation of the digger and the hazards
associated with it.
ALWAYS check with authorities for underground utilities before digging a hole. Serious injury or death could result from
contact with gas or electric lines.
ALWAYS check the tractor owner’s manual for instructions on operation, attachment of 3-point equipment and safety .
ALWAYS make sure that all safety shields are in place and tightened down. Do not operate this post hole digger if any
shields are missing. Contact SpeeCo, Inc. at 1-800-525-8322 for replacement p art(s).
ALWAYS make sure that the auger point and cutting edges are intact and in good working order before using this digger.
NEVER allow children or other persons to ride on the Tractor or Implement. Falling off can result in serious injury or death.
NEVER allow children to play on or around Tractor or Implement. Children can slip or fall off the Equipment and be injured
or killed. Children can cuase the Implement to shift or fall crushing themselves or others.
NEVER allow others within 20 feet while operating the post hole digger.
NEVER operate post hole digger without all guards in place.
ALWAYS ensure the driveline is securely locked onto the PTO.

OPERA TING SAFETY
ALWAYS operate this post hole digger from the tractor seat.Only one person should operate the digger .
NEVER attach the post hole digger with the tractor engine running.
NEVER operate the post hole digger with anyone near or in contact with any part of the implement, PTO driveline or auger .
Serious injury or death could result from entanglement with moving parts.
ALWAYS make sure that the tractor brake is set before digging a hole.
ALWAYS keep hands, feet and clothing away from power-driven parts during operation.
NEVER manually position the auger or manually force the auger into the ground.
ALWAYS make sure that the tractor engine is shut off and the PT O drive is disengaged before leaving the tractor seat.
NEVER move the tractor with the power-take-off in the ON position.
NEVER exceed 540 RPM PTO operating speed.
NEVER operate the post hole digger when the auger point is more than 6 in. above ground level. Operating the digger in
elevated positions may cause the PTO driveline “U” joints to bind resulting in equipment damage and operator injury .
ALWAYS turn of f the digger immediately if an immovable object is encountered to prevent damage to the gear box or
driveshaft and possible injury . A shear bolt is provided but may become welded to the input shaft if the driveshaft is left
running after being sheared.
.
TRANSPORT ATION SAFETY
NEVER allow anyone to ride on Implement.
Make certain the slow moving (SMV) sign and other reflectors are clearly visible. Follow local traffic codes for slow moving
vehicles when transpotting on public roads.
REP AIR AND MAINTENANCE SAFETY
ALWAYS perform maintenance operations such as lubrication, adjustments or repairs on the post hole digger with the
tractor engine off, the PTO drive disengaged and the auger point resting on the ground.
ALWAYS use the correct shear bolt (Grade 5). NEVER use or replace the shear bolt with one that is longer than the one
specified in the manual (5/16” x 2-1/2”).
Periodically inspect all moving parts for wear and replace when necessary with authorized service parts. Look for loose
fasteners, worn or broken parts, and leaky or loose fittings. Serious injury may occur from not maintaining this machine in
good working order.
Do not modify or alter this Implement. Do not permit another to modify or alter this Implement, any of its
components or any Implement function. Any modification will void the warranty.

ASSEMBLY INSTRUCTIONS
IMPORT ANT: The gear box is shipped without lubricant. Fill the top hole with 80W-90 lubricant or the equivalent.
Approximately 1.75 quarts of the lubricant is enough to lubricate the gears and bearings. A
greater amount will not harm the gear box. Do notfill 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 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. pull pins with nut and
lockwasher (7) as shownin 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 supplied with the gear box. When in
place secure with the cotter pins provided. NOTE: Input shaft shield (9) and output shaft shield
(8) are already attached to the gear box.
STEP 5: Attach the auger (18,19,20, 25 or 26 ) 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 the
nuts.
STEP 6: Attach the driveline (11) to the gear box input shaf t 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 (24) from the hardware kit in the hole on the yoke that aligns with the 3/16
in. groove on the gear box input shaft. T ighten loosely .
ATTENTION: THE 3/8 IN. HEX CAP SCREW PROVIDES SHEAR PROTECTION. USE A GRADE 5
3 IN. BOL T ONL Y TO A VOID DAMAGE TO THE GEAR BOX OR AUGER.
IMPORT ANT: 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 (1 1) to the tractor PTO shaft. Push in the spring-loaded pin
in the splined yoke 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 the lower chain on the driveline to the boom (1). Attach the upper chain to the
hole on the gear box shield (9).
STEP 9: Check all nuts and bolts for tightness. S tabilizers 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 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

OPERATING INSTRUCTIONS
WARNING: Read and thoroughly understand all instructions and safety information before operating
this post hole digger Failure to do so may cause serious injury or death. Do not allow anyone to
operate this post hole digger who has not read this manual.
STEP 1: Af ter mounting the digger to the tractor , lower the auger point slowly to the ground at the desired digging
angle before engaging power.
STEP 2: Engage the power-take-off and start digging at a slow speed, lowering the auger slowly as it begins to dig.
STEP 3: Increase speed as the auger goes deeper . The type of soil will determine the proper auger speed. If the
soil is extremely hard, it will generally improve operation to vary the speed of the auger at times.
STEP 4: When the auger has reached the desired depth, spin it momentarily at a high speed to clear the hole of
dirt. Reduce speed before withdrawing the auger from the hole.
STEP 5: Disengage the power-take-off after withdrawing from the hole and move the tractor to the next hole location.
GENERAL MAINTENANCE
REFER TO ILLUSTRATION C
WARNING: Always perform maintenance operations with the tractor engine off, the PTO drive disengaged
and the auger point resting on the ground.
1. To remove the auger from the gear box output shaft, take out the two 1/2 in. x 3-1/2 in. hex cap screws (15).
2. To remove the driveshaft from the gear box input shaft, take out the shear pin bolt (12) and 1/4 in. set screw (24).
3. Check the oil level after every fifty hours of use. Use 80W-90 lubricant and fill to oil level plug. All replacement
lubricant should be of this type.
4. The universal joints 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.
