Safe Operation Tips
In addition to the design and conguration of equipment, hazard control and accident
prevention are dependent upon the awareness, concern, prudence, and proper training of
personnel in the operation, transport, maintenance and storage of equipment. Lack of attention
to safety can result in accident, personal injury, reduction of efciency and, worst of all, loss
of life. Watch for safety hazards and correct deciencies promptly. Use the following safety
precautions as a general guide to safe operations when using this machine. Additional safety
precautions are used throughout this manual for specic operating and maintenance procedures.
Read this manual and review the safety precautions often until you know the limitations. Please
review the safety labels located in the back of this manual.
Tractor and/or Front End Loader Precautions:
• Read the tractor and/or loader operator’s manual to learn how to operate your tractor and/or
loader safely. Failure to do so could result in serious injury or death and equipment damage.
• It is recommended that your tractor be equipped with Rollover Protective
System (ROPS) and a seat belt must be used for all loader operations. If your tractor is not
equipped with a front end loader, you must add wheel ballast or
front weight for stability.
• Move wheels to the tractor manufacture’s widest recommended settings to increase stability.
• For better stability, use tractor with wide front axle rather than tricycle front wheels.
• While the backhoe is attached to your tractor, move and turn the tractor at low speeds
(10 MPH maximum).
• Stop tractor engine, place transmission in park (or neutral), engage parking break, lower
loader arms to ground, cycle all hydraulic controls to relieve pressure, allow machine moving
parts to stop, remove ignition key to prevent any unauthorized person from starting engine
before dismounting tractor or serving, repairing, or making adjustments to the equipment.
• Wear personal protective equipment (PPE), such as, but not limited to, protection for eyes,
ears, lungs, head. hands and feet when operating, servicing, or repairing equipment. Avoid
wearing loose clothing or jewelry that may catch and entangle on equipment moving parts.

Backhoe Precautions:
• DO NOT operate the backhoe unless it is rigidly attached to the tractor.
• KNOW your controls. Read this operator’s manual and the manual provided with
your tractor. Learn how to stop the tractor, the engine and the backhoe quickly in an
emergency.
• PROVIDE adequate front end weight to counter-balance the backhoe at all times. 20% of
the total tractor, loader and backhoe weight must be on the tractor front axle. If unsure of
weight distribution, at a weight scale. Total vehicle weight, including backhoe and counter
weights, must not exceed the ROPS certicate for gross vehicle weight.
• BE SURE the area is clear of overhead or underground utilities or other hazards.
• POSITION a barricade around the work area.
• KEEP all bystanders a safe distance away.
• DO NOT attempt to enter operator’s platform backhoe by using the stabilizers as a step.
• OPERATE from the backhoe operator’s seat only.
• ALLOW only one person to operate the backhoe at any time.
•
REMOVE travel pins before attempting to operate the backhoe.
• NEVER dig with the backhoe unless the stabilizers are properly set.
•
DO NOT dig under stabilizers or tractor backhoe. Soft ground or sandy soil can cause cave-ins.
• KEEP BUCKET away from the stabilizer area to avoid possible stabilizer damage.
• ALWAYS swing bucket uphill to dump when on a hillside and keep loaded bucket low.
• SET BRAKES and block wheels when operating on hills and banks to avoid dangerous
runaway.
• WATCH for overhead wires. DO NOT touch wires with any part of the backhoe.
• NEVER allow a person to work under a raised bucket.
• NEVER lift a person with the backhoe.
• DO NOT use the backhoe as a battering ram. Use the backhoe only for digging.
• ALWAYS lower the backhoe bucket and stabilizers to the ground, shut off engine, and
apply the parking brake before getting off unit, or when not digging.
• NEVER leave the tractor unattended with the engine running.
• DO NOT attempt to raise the tractor off the ground or move the tractor forward or
backward using the backhoe dipper stick or bucket.
• Do not attempt to use the bucket as a tow hitch by attaching chains to the bucket and
driving the tractor forward to drag logs, stumps, etc.

Transportation
• Comply with state and local laws.
• ALWAYS engage safety locks and pins before transporting backhoe.
• DO NOT drive the tractor near the edge of a ditch or excavation.
• ALWAYS use accessory lights and devices when transporting on a road or highway
to warn operators of other vehicles. Check your local government regulations.
• Maximum transport speed for any WoodMaxx implement is 20 mph on paved
surface and 10 mph maximum on unpaved surface. Do not exceed. Never travel at
a speed which does not allow adequate control of steering and stopping. Rough
terrain requires a slower speed. Traveling at excessive speed on rough terrain that
causes violent shaking or bouncing of the implement will damage the attachment
point on the implement and/or the tractor. This type of damage is not covered
under warranty.
• Use the following maximum speed - for paved surfaces only:
• 20 mph when weight is less than or equal to the weight of tractor.
• 10 mph when weight is more than the weight of the tractor.
SAFETY INFORMATIONSAFETY INFORMATION
You must know and obey all state and local laws when transporting equipment.
It is your responsibility to know and understand the laws in your area.

ASSEMBLY INSTRUCTIONSASSEMBLY INSTRUCTIONS
Slowly and carefully back up your tractor until
you are close and centered on the backhoe
as pictured. (Turn off the engine and set the
parking brake)
Measure to ensure that there is enough space
around the PTO shaft for the pump to slide
onto the shaft (see page 14). There must
be 7-3/4” in the area
indicated by the arrows.
This is not uncommon
on smaller tractors, if you
do not have the required
clearance, a PTO shaft
extender must be installed.
PTO shaft extender installed (red arrow) This
quick release PTO extender part # SP16612
can be purchased through WoodMaxx or at
most agricultural supply store.
Pump slides right onto the PTO shaft, there are
no pins required.

This is the NEW Woodmaxx PTO pump for all models of WM series backhoe. It
requires no gear oil and is sealed and maintenance free. Simply attach your hoses,
slide the pump over the tractor PTO output shaft and afx the chain to a place on your
tractor so that the pump cannot rotate due to the torque of the PTO or slide off.
Ax chain to your
tractor on this side
of the pump as
shown above.
WoodMaxx™

15
ASSEMBLY INSTRUCTIONSASSEMBLY INSTRUCTIONS
Attach the chain to a frame member to the
right side of the pump as shown. This secures
the pump and prevents it from rotating due to
torque of the PTO.
Fill the oil reservoir with 4 gallons of hydraulic
oil. (See page 22 of the this manual for proper
oil viscosity in your region). After priming the
system you will need to add an additional 2-3
gallons, but do NOT do so at this time.
Lower the draw arm of your tractor and
remove the top link at this time. It is important
to do this before proceeding to the next step
because the draw arm lift mechanism on some
tractors can obstruct removing the top link
pin once the draw arms are attached to the
backhoe (see red arrow).
Inspect the top link pin that you will use to
attach the top link to the tractor. This pin
must be in good serviceable condition, if you
detect any defects, you must replace it with an
approved top link pin, do not use a bolt or any
other un-approved pin. WoodMaxx does not
provide this pin since it is part of your tractor.

ASSEMBLY INSTRUCTIONSASSEMBLY INSTRUCTIONS
Install the I-beam top link as shown. Insert and
secure the top link pin to your tractor.
Raise the I-beam top link and support as
shown using wire, strap, string, or similar.
(This will keep it out of the way for the next
step)
Pull backwards on the support leg/ hydraulic
thumb lever so that the lever will allow for
“support leg” function. Note – only backhoes
with hydraulic thumb option, all other skip this
step.
Start you tractor and engage the PTO at
idol speed. After a minute or two, the oil will
circulate sufciently so that you can actuate
the support legs. Standing on the side of the
machine and clear of any pinch points, slowly
push the support leg levers forward so that
the frame of the backhoe lifts off of the crate
slightly.

ASSEMBLY INSTRUCTIONSASSEMBLY INSTRUCTIONS
Raise the backhoe frame so that it is not less
than 10” off of the ground (red arrow) and
level from left to right. Note – larger tractors
can allow for more ground clearance if you
prefer, but it will reduce overall digging depth
capability.
Turn off the engine to your tractor at this time.
Prepare the 3-point hitch for attachment using
the following steps. Align the top link so that
when you back up the tractor that you do
not contact the backhoe frame. Suspend the
top link using wire, straps or similar as shown
(blue arrow). Align the draw arms so that when
backing up the draw arm attachments pass into
the backhoe frame attachment point. (black
arrows) Here you can see we used a driveway
stake zip tied to the draw arms to allow for the
proper spacing during this step. (red arrows)
Install the draw arm pin on the left and right
side.
Right side view.
Hint – a spud wrench
aligning tool may be helpful
to accomplish this step.

ASSEMBLY INSTRUCTIONSASSEMBLY INSTRUCTIONS
Slightly loosen the hydraulic tting on the
pump and tank so that you can adjust the
hoses so that they do not drag on the ground
or rub on any frame members. This will be
different for everybody, you can see that here
we made a loop with the suction line to take
up the slack. Be sure to tighten all tting when
done. (15/16” wrench, 1-1/4” wrench, crescent
wrench)
Prepare the remaining top link assembly
components by removing the bolt.
Note - When installed, the spacer bushing
should be mounted on the bolt as shown here.
Stop here and read the important top link
information on page 23-24.
