Caterpillar® 236, 246 and 248 Skid Steer Loaders
Designed, built and backed by Caterpillar to deliver exceptional performance and
versatility, ease of operation, serviceability and customer support.
Performance and Versatility
Cat 3034 and 3034T engines provide
high engine horsepower and torque
allowing part-throttle operation for
lower sound and fuel consumption.
An exclusive anti-stall feature
incorporated into the hydrostatic
drivetrain delivers maximum power
to the wheels and work tools without

coupler makes work tool changing
quick and easy and interfaces with
a wide selection of Caterpillar Work
Tools. pg. 4-7
Ease of Operation
Operator comfort and ease of operation
are designed into the operator’s station
from every aspect. Ergonomic features
such as low-effort joystick controls,
a comfortable padded armrest and
adjustable, contoured seat reduce
operator fatigue. The loader arms,
quick coupler and cab are all designed
to provide excellent visibility to the
work tool. Even more cab options are
available to further enhance operator
comfort. pg. 4
Built for tough work
The 236, 246 and 248 Skid Steer Loaders,
with many work tool options, are highly
versatile, compact construction machines.
They are designed to deliver traditional
Cat reliability, durability and productivity
in the toughest working conditions.
2
Serviceability
The 236, 246 and 248 are designed for
quick and easy routine maintenance and
service. The rear door opens 90 degrees
and the cooling package tilts up out of
the way for unparalleled access to the
engine compartment. Maintenance
points are grouped in easy-to-reach
locations and all filters are vertically
mounted to reduce fluid spills. The cab
tilts to the rear, exposing hydraulic
pumps, motors, valves and lines.
Both the hydraulic tank and the radiator

High Flow Hydraulics (for the 248 only)
Caterpillar’s high flow system utilizes
a load sensing variable displacement
pump which will provide maximum
pressure to the work tool at any engine
speed. The system is capable of sending
100% of engine power to the work tool;
maximising productivity. With high
hydraulic horsepower, the Cat 248
allows optimal operation of complex
hydromechanical work tools such as
cold planers and stump grinders.
3
Operator Station
Operator fatigue is reduced and production is increased as a result of pilot operated
joystick controls.
Cab. The ergonomic cab is designed to
provide the operator with easy to use, pilot
operated controls in a comfortable working
environment. Twin tilt cylinders, coupled
with a wide cab opening, three-point grab
handles and deep, skid resistant steps make
it easy for an operator to get in and out of
the cab. The entire cab also tilts rearward to
provide excellent service accessibility.
Standard Equipment. The standard offerings
for the Cat Skid Steer Loaders operator
station are a ROPS/FOPS cab, an adjustable
fore/aft static seat with a retractable seat belt,
armrests, hand and foot throttles, a rear wall
liner, instrumental panel, floormat and pilot
hydraulic control system.
Cab Options. The deluxe cab includes a
suspension seat, headliner, horn and
additional working lights. A cold weather
package is also available that includes
sliding side windows and cab heater.
A cab door is also available.
Instrument Panels. Two instrument panels are
located in the upper right and upper left hand
corners of the cab to maximise the viewing
area to the loader when in the raised position.
Hydraulic Joystick Controls. The Skid Steer
Loader is controlled by two hydraulic
joysticks. The right lever controls loader
functions and the left lever controls
machine direction.
Left Control Panel. The upper left
control panel contains standard
equipment including indicator lights
(LED’s), key start switch, hour meter,
parking brake switch, glow plug
switch, auxiliary override switch
and continuous flow.
Optional equipment includes an
automatic self-leveling switch and
auxiliary electrical control switch.
4
Right Control Panel. The upper right
control panel contains a fuel level
gauge and an interior lamp, as well as
provisions for an optional rotating
beacon, front and rear-working lights.
Operation. The pilot operated joystick
controls and the “S” control pattern used
to operate the Skid Steer Loader reduces
operator fatigue. The accelerator pedal can
be used during load and carry, excavating
or backdragging, a hand throttle allows you
to run at constant speed. An optional fourth
function control allows the operator to
hydraulically side shift cold planers or
angle brooms.
Auxiliary Hydraulics. On/Off auxiliary
hydraulics are standard on the 236 and 246
allowing for work tool operation. Optional
proportional hydraulics are available to enable
the operator to vary the amount of flow to
the work tool. Proportional hydraulics are
standard on the 248.
Power Train
Caterpillar Hystat power train delivers aggressive performance and easy operation.
Engine. Caterpillar 3034 provides high
engine horsepower and high levels of
flywheel torque.
Hydrostatic System. Closed-loop, highoutput hydrostatic system and exclusive
anti-stall system deliver maximum torque
to the wheels. This system allows the
Skid Steer Loaders to be used at any throttle
setting without the risk of stalling the
engine.
Chains. High-strength, pre-stressed
chains run in an oil bath for continuous
lubrication. Chain wear adjustment is
provided via slots in the axle housings.
Drive Axle. Each drive axle is forged,
induction hardened and sealed for long life.
Parking Brake. The parking brake is spring
applied and hydraulically released.
The system is inherently safe as it automatically applies the brakes as soon as
the engine is stopped.
Dealer Support. Unmatched dealer support
and factory tested to ensure years of troublefree operation. The hydraulic system is
cleaned to a level exceeding industry
standards. The machine is dynamometer
tested on a rolling road to deliver the
performance and reliability customers
expect from Caterpillar.
Two Speed Option (236 and 246 only).
The driver can select either a turtle mode,
with up to 10.4 km/h or a rabbit mode with
speeds up to 19.1 km/h.
5
Serviceability
Owning and operating costs are reduced through long service intervals and
convenient maintenance.
Service Access. Service accessibility for
Caterpillar Skid Steer Loaders is a key
differentiator when compared to its
competition. Simplified service is built
into the design of the Cat Skid Steer
Loader and maintenance points are
grouped in easily accessible locations.
Engine Access. The rear engine compartment door opens 90 degrees to expose an
engine that is mounted lengthwise in the
frame. This arrangement gives access to
both the left and right side of the engine.
Filters. All filters are easily accessible.
Spin-on filters are vertically mounted for
spill-free changes.
Cooling System. The radiator, hydraulic
oil cooler and grill tilt up to give more
access during maintenance or to allow
cleaning between the grill and cooling
package.
Tilting Cab. The cab tilts rearward
and is held in place by a self-latching
mechanism exposing all pumps,
motors, valves and lines to make
repairs easy if necessary.
Ground Level Maintenance. Sight gauges
are conveniently located for daily fluid
level checks. S•O•Ssm oil analysis ports
are installed to allow regular monitoring
of the engine and hydraulic oil quality
for preventive maintenance. In addition,
ecology drains are fitted to the engine
oil pan and hydraulic system, helping
prevent spills. The axles require no
greasing as they are sealed for life.
