Introduction
The Cat 527 Skidder is designed and built specifically
for log skidding applications. The 527’s extended track
roller frame and weight-forward bias make it well suited
for mountainous and soft underfoot logging opera-
tions. The skidder’s ergonomic and spacious operator’s
environment allow for increased comfort and produc-
tion. The 527’s standard forestry guarding and under-
carriage design ensure the durability required in logging
applications. Both Cable and Swing-boom Grapple con-
figurations are provided to suit a wide range of skidding
applications.
Features 527:
●
Field proven Cat 3304 diesel engine
sets the industry
standard for reliability and durability, delivering high
horsepower for more drawbar pull, improved skid-
ding performance and ease of operation.
●
Large, heavy duty torque converter
, reduces the ten-
dency for track-to-ground slip, reduces the need for
up and downshifting and protects power train com-
ponents contributing to longer component life.
●
3 speed planetary powershift transmission
works best
in high-pull applications and is well suited for large
load and steep terrain skidding.
●
Heavy-duty track roller frame
extended to the rear sig-
nificantly improves traction capability under heavy
loads and uphill skidding applications.
●
Wide gauge and long track roller frames
provide out-
standing sidehill stability.
●
Improved flotation
— More track on the ground dis-
tributes tractor weight and propulsion forces over a
much larger area than conventional track skidders.
This improves flotation capabilities, gradeability and
significantly reduces soil impact.
●
Load sensing hydraulic system
— Variable displace-
ment pressure compensating hydraulic system provides
reduced power requirements when there is not hydrau-
lic demand, significantly reduced heat generation,
and improving fuel efficiency.
●
Auto-grab feature
— provides constant grapple tong
pressure without continuous hydraulic pump demand.
●
Superior component durability
— Final drives are
raised above the work area, isolating the power train
from ground impact shock and abrasive materials.
●
Excellent ground clearance
— no diagonal braces
allow the skidder to pass over stumps and debris,
reduces maneuvering for reduced cycle times and
minimizes soil impact.
●
Smooth belly pans
— Less likely to hang up in mud and
debris in soft ground or swamp logging applications.
●
Easy and comfortable operating environment
— The
seat is angled and controls are easily reached to reduce
operator fatigue and increase productivity. Optional
enclosed ROPS/FOPS cab allows excellent front and
rear viewing, and is pressurized for sound level reduction.
●
Single lever
grapple control and blade control.
●
Less service time
— Major components are made as
modules and most can be removed without removing
others, and ground-level access provides convenient
servicing to most filters and lube points.
●
Cable and Swing Boom
configurations provide the
versatility needed to match the skidder to a wide vari-
ety of skidding applications.
