Compact Track Loader Drives
Performance Advantages
Servo system designed for high displacement ratio
 CT07 = 2.3:1 and CT05 = 2.5:1 displacement ratios
 Allows higher speeds with same pump flow – higher productivity
Low pressure “soft shift” servo system
 Reduces shift harshness = operator comfort
 Other two-speed units use a high pressure shift servo system
Designed for Exceptional
Performance
Fairfield's CT05 and CT07 Torque-Hub®
final drives are specifically designed for
the harsh working environment they
will encounter with demanding mobile
applications, such as compact track
loader (CTL) machines. Our solution
uses an integrated axial piston motor
and a compact, two-stage planetary
reduction, featuring a high displacement
ratio between maximum and minimum.
The lower minimum displacement
values allow for higher speeds even
if pump flow is reduced by lowering
engine speed to achieve mandated
emission requirements (tier 4).
Fairfield provides additional minimum
displacement choices to fine tune
machine performance.
Key features:
 High efficiency (minimal power loss
at high speed)
 Higher travel speeds (10-12 mph)
 2-speed design & 3-speed capability
 Softest shift in the industry
 High durability brake & seal
These performance advantages make
these drives ideal for use in various
construction equipment, including
CTLs, trenchers, track-driven utility
vehicles, small compaction machines,
mini-excavators and small pavers.

Brake design
 Exceeds 100 panic stop qualification test without fade
 Reduced running losses at high speed due to brake location
 Tests have shown brake drag can be as much as 1.5 hp less
 Brake system can be easily serviced through the cover of the gearbox
Active brake flushing
 Providing flow to keep heat managed in critical shaft seal area
 Considered to be “deep case” flushing
Double wall floating carrier = improved load sharing
 Extended planet gear and planet bearing life
Improved start-up torque
 Axial piston vs. competitive radial piston designs
