Introduction
The commercial THM13HD Horizontal Tractor Mount Log Splitter is designed for tough
applications elevated or on the ground. With up to 20 tons of splitting force, the
THM13HD will handle most of your commercial log splitting needs. The log splitter
attaches to any tractor with a class 1, 2, or 3 three-point hitch.
Power for the THM13HD comes directly from tractor-supplied hydraulic pressure. The
maximum splitting force is determined by the pressure output of the tractor’s hydraulic
sys- tem. For example, 3000 psi of pressure produces 20 tons of splitting force, 2000 psi
produces 12.5 tons, and 1500 psi produces 9 tons.
An attractive, powder-coated finish provides the finest protection available and Iron &
Oak’s rigid, quality-control and component testing help ensure years of productive, reliable service. Since 1982, the name Iron & Oak has stood for quality and reliability when
it comes to log splitters and wood processing products.
Iron & Oak Commercial Products offers the finest commercial log splitter on the market
today!
✔ Rugged, heavy-duty construction for years of exceptional service.

Operation
Iron & Oak Products’ dealer or call the Sales and Service representatives at our
main headquarters. Proper care is your responsibility.
When operating the log splitter make sure you
are standing in the safe operating area, as
shown in these pictures. You must stay in the
safe operating area at all times when the
splitting wedge is in motion (whether extending or retracting). Never place any part of
your body into a position which would cause
an unsafe operating condition.
1. Place the tractor and log splitter on flat, dry
ground. Make sure you read all
recommendations from the “Safety”
section before using the log splitter.
2. Make sure both ends of the log you are
splitting are cut as square as possible.
This will prevent the log from sliding out of
position while under pressure. All logs
should be 24 inches long or shorter.
Do not attempt to operate the log splitter without fully understanding
all our instructions, safety precautions, and/or warnings. If any doubt
or question arises about the correct or safe method of performing anything found in this or other Iron & Oak

split, DO NO T reach forward and
attempt to catch the split wood — let it
fall to the ground.
d. Once the wedge reaches its full for-
ward travel, pull back on the control
lever to the full retract position. The
ram of the cylinder will automatically
retract into the cylinder. It is not
necessary to hold the control lever as
the cylinder retracts. Stop the wedge if
the log sticks (see caution below).
When the cylinder is fully retracted,
the control valve will automatically

Inspection and Maintenance
General Maintenance Check (before operating)
The hydraulic system (hoses, cylinder, and pump) should be carefully inspected before
each use. Also, inspect the mechanical parts at the same time. Make sure all clamps,
nuts, bolts, fittings, etc. are properly installed and tightened.
WARNING
Do not check for leaks with your hand. Leaks can be located by
passing a piece of cardboard or wood around the suspected leak and
looking for discoloration. High-pressure fluid escaping from a very
small hole can be almost invisible. Escaping fluid under pressure can
have sufficient force to penetrate skin, causing serious injury or even
death. If fluid is injected into your skin, it must be treated immediately by
a doc- tor familiar with this type of injury.
Always replace frayed, kinked, or cracked hoses and/or other damaged hydraulic
components with Iron & Oak Commercial Products’ authorized parts and components
specified in the “Parts” section of this manual. Replacement parts from secondary
suppliers (not original Iron & Oak replacement parts) can lead to product damage and/or
personal injury, and will void the warranty.
Should it become necessary to loosen or remove any hydraulic fitting or line, be sure to
relieve all hydraulic pressure by shutting off the tractor and moving the valve control
handle back and forth several times until no cylinder movement is visible.
Storage
Between each use of the log splitter, we recommend applying a rust preventative (WD-40
or equivalent) to any bare metal areas on the top of the rail.
The following section will detail procedures for checking your log splitter should you
encounter a malfunction. Iron & Oak Commercial Products, Inc. recommends that you
do not attempt to make repairs to the log splitter. In the long run, it is better to take your
log splitter to a servicing lawn and garden dealer for repairs.

move.
1. Check tractor hydraulic tank to make sure it is properly filled.
2. Make sure the tractor hydraulics are functioning.
4. Disconnect the wedge from the cylinder. Grasp the hydraulic cylinder shaft
and try to pull it out. If the rod comes out easily, you will need to rebuild
or replace the cylinder.
1. Check the output of the tractor’s supply oil.
2. For PTO models check the output of the PTO pump.
1. Check the slide rail or wedge assembly for damage.
2. Push the valve handle to the retract position. If the handle will not stay in
this position, adjust valve detent, as described below.
Detent Adjustment Procedure
a. Locate adjustment screw on lower side of valve body.
b. Loosen locknuts.
c. Turn adjustment screw clockwise one-half turn and retighten locknuts.
d. Start tractor hydraulics and test for detent operation. If detent does not
work, repeat Steps b and c.
3. If adjustment of detent does not correct the problem, replace the valve
assembly.
