Milton CAT 517 User Manual

517
Track Skidder

Power Train

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.

Application Flexibility

The 517 Skidder provides unsurpassed performance
and application flexibility due to superior balance,
torque converter power train and expanded track and
grapple/arch options. The versatile PAT blade makes
the 517 a multi-purpose machine.

Undercarriage

Use of D5H 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.

Customer Support

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.

Operator Station

Excellent all-around viewing area, angled seat, and
easy-to-reach controls reduce operator fatigue and
increase productivity. Available with enclosed cab or
open canopy.

Cable Skidder

The 517 is also offered in a cable configuration to
meet application demands in severe slope and
mountainous terrain.

Serviceability

Less service time means more working time. Major
components are made as modules and most can be
removed without disturbing or removing others.
