Features
PowerTrain
The field proven Cat ® 3304 DIT Diesel engine,
heavy-duty torque converter and three-speed
transmission are matched to deliver high
horsepower for more drawbar pull, improved
skidding performance and ease of operation.
ApplicationFlexibility
The 527 Skidder provides unsurpassed
performance and application flexibility due
to superior balance, torque converter power
train, several track options, and either cable
or swing-boom grapple configurations.
Undercarriage
Use of D6R sized heavy-duty track prolongs
the life of the key undercarriage components,
including rollers, idlers, pins, bushings and shoes.
An extended track roller frame places more track
under grapple/winch and enhances balance.
Hydraulics
The load sensing hydraulic system reduces
horsepower consumption and system heat.
A single lever controls grapple and tong
hydraulics, reducing operator efforts for improved
productivity. Exclusive Auto-Grab hydraulics
maintain constant tong gripping pressures to
compensate for shifting loads.
OperatorStation
Excellent all-around viewing area, angled seat,
and easy-to-reach controls reduce operator fatigue
and increase productivity.
CustomerSupport
Your Cat dealer offers a wide range of services
that can be set up under a customer support
agreement when you purchase your equipment.
The dealer will help you choose a plan that can
cover everything from machine and attachment
selection to replacement, to help you get the best
return on your investment.
