301.6C/301.8C Mini Hydraulic Excavators
Designed to deliver reliable performance, versatility and ease of operation.
Engineered Durability –
The heavy-duty structures and clean lines of
the Cat 301.6C and 301.8C ensure long life
and reduce maintenance costs in tough,
demanding applications.
Low Operating Costs
Protected front linkage lines, extra thick
side panels and protective counterweight
help reduce impact damage and costly
repairs. Service points are easily
accessed through a large, rear door
and a 500-hour engine oil change
period lowers operating costs. pg. 6
Performance and Versatility
High dig forces, fast cycle times and
high bucket rotation angles deliver the
productivity that customers demand.
A choice of stick lengths, Cat®Work
Tools and dozer float function make
the 301.6C and 301.8C Mini Hydraulic
Excavators even more versatile. pg. 5
Comfort and Ease of Operation
Cab or canopy, the 301.6C and 301.8C
offer spacious and comfortable work areas
with expansive legroom. Features like
automatic swing lock, power socket,
suspension seat, ergonomic controls
and well-positioned air vents add to a
productive work environment. pg. 4

High digging forces and fast cycle
times ensure that the Cat C-Series Mini
Excavators deliver the productivity that
customers demand.
Stick Options. A choice of standard or
long stick enables matching of machine
to application.
Bucket Angle. High rotation bucket
angle combines good spoil retention
and flat back trench characteristics.
Dozer Blade Float Function. The dozer
float enables easy ground leveling for
landscaping and finishing applications,
as well as more efficient clean-up.

lines are routed above the boom and stick
to help reduce damage and downtime.
Service Access. A large, swing-out rear
door allows access to major components
and service points within the engine
enclosure, including:
• Air filter
• Engine oil check and fill
• Engine oil filter element
• Radiator reservoir tank, check and fill
• Vertically-mounted, spin-on fuel
filter/water separator

valve allows easy sampling of hydraulic
fluid for preventive maintenance.
500-Hour Oil Change. The 500-hour oil
and filter change period helps keep
operating costs down.
Automatic Engine Idle. Automatically
lowers engine revs when not in use to
conserve fuel and lower environmental
noise/emissions.
