The Cat® 904H Compact Wheel Loader delivers high
performance with outstanding versatility. Spacious cab
with joystick control keeps you comfortable throughout
the work day, allowing you to get more done. Loader design
delivers strength and durability with superior control.
Do more with one machine with the skid steer loader style
coupler. This coupler allows the use of Cat Skid Steer
and Multi Terrain Loader hydromechanical Work Tools
on the Cat Compact Wheel Loader for greater machine
versatility. Expand your business with the new 904H.

Operator Station
Superior comfort keeps you productive, all day long.
Cab Comfort
Spacious, comfortable cab with increased oor space helps you stay productive. Canopy, cab with heat
or cab with heat and air conditioning are available. All cabs are pre-wired, making it easy to install future
options. A backlit LED display provides system information and is conveniently located in the operator’s
line of sight. Right side window opens fully for better ventilation or communication with workers.
Low Effort Controls
Pilot hydraulics for implement control and use with Cat Work Tools keep operator fatigue low.
No linkage to adjust or wear ensures consistent control over the life of the machine. The multi functional
joystick contains a 3-position Forward/Neutral/Reverse switch, an easy to control third function auxiliary
hydraulics switch, and (when equipped) optional bucket positioner (return to dig) switch.
Excellent Visibility
The loader arms have been designed with visibility to the work tool in mind. Wide cab glass area and
sloping rear hood provide both a 360 degree panorama and visibility within a few feet of the machine.
This makes for safer operation and reduces machine damage caused by collision with unseen obstacles.

Power Train
Designed for power, durability and performance.
Engine
The MHI S4Q2 Turbo engine meets EPA Interim Tier 4 emissions requirements
and delivers superior power to help you get more done.
Chassis
Rear axle oscillation helps assure four wheel ground contact for optimum traction
and stability. Heavy duty axles with outboard planetary reduction gears are built
for durable performance. Optional differential lock is available in the front axle
only or both axles and can be easily engaged by a foot switch to the left of the
steering column to increase tractive effort in poor underfoot conditions.
Power Train
Two-speed closed loop hydrostatic transmission delivers smooth transition
from full rimpull to runout. Precise inching control and smooth acceleration
and deceleration minimize operator fatigue. Optional speed (creeper) control
and hand throttle are also offered.
Ride Control
The optional Ride Control System further enhances the already smooth road
handling of the machine, resulting in increased operator comfort and higher
productivity. It is suited for extreme applications where operators need to maintain
bucket material load or carry a heavy work tool and have a smooth ride.
Linkage
Built for strength.
Z-Bar Design
The high performance Z-bar
loader design is built for strength,
visibility and versatile attachment
usage. The Z-bar linkage gives the
operator a clear view to the work
tool and excellent dump clearance
while maintaining good cycle times.

Serviceability
Easy access and minimal maintenance requirements reduce downtime.
Convenient Service Features
Easy to lift engine hood provides easy access to all major
•
components and service points from ground level.
S•O•S valve is conveniently located in the engine bay for
•
analyzing hydraulic system cleanliness and pressure taps
for service analysis, prolonging machine life.
Two stage air cleaner with primary and secondary
•
element and a visual restriction indicator improves
service life.
Auxiliary fuses, relays and other electrical service points
•
are all located together behind a locked door for ease
of servicing.
Spin-on engine and hydraulic oil lters and fuel lter
•
with water separator are vertically mounted for easier
servicing.
Heavy-duty wiring increases electrical durability and
•
is multicolored to ease diagnosis and fault nding.
Water resistant sealed connectors prevent dust and
moisture from interfering with the electronics.
Wheels and tires are mounted on studs rather than
