The Cat® 301.7D gives you a blend of power, control and stability to make your
workingday easier and more productive.

3

Performance

Powerful digging combined with smooth control.

Dig Force

The new 301.7D boasts high bucket and
stick forces making it an impressive and
productive excavator.

The choice of two stick lengths allows
the customer to congure his machine to
deliver even higher stick forces or reach.

4

Stability

An extending undercarriage and fold out dozer blade allow
themachine to be congured for optimum performance.
Bladeextensions are retained with the dozer making them
easy to use and ensuring that they are not lost.

Dozer Float

Ground levelling and nishing applications are fast and easy
withthe dozer oat function engaged making site clean-up much
more efcient.

Long Dozer Option

The optional longer dozer blade enables improved ‘dig to blade’
characteristics to give easier on site clean up.

100% Pilot Controls

Delivers excellent machine control and lifetime ‘as new’
performance eliminating the need for linkage and cable
maintenance, lowering owning and operating costs and
resulting in less downtime.

5

Versatility

Flexibility built in for a variety of jobs.

High Flexibility

Compact in size and with a transport weight under 2000kg
(4,500 lb), the 301.7D can be transported easily using a
conventional trailer and pick up truck or transit van.

The sturdy hoisting eyelets on the cab roof enable the
easy and rapid relocation of the machine between sites.

Automatic Swing Lock

Safe transportation of the machine is aided by the
Catautomatic swing lock which locks the machines
upperbody in place when the control console is raised
orthe engine is stopped.

Work Tools

A range of work tools are available including buckets, hammer and auger to take advantage
of the machines versatility. All these tools are matched to the machine to optimize
performance and deliver excellent value through productivity and long life.

Auxiliary Hydraulics as Standard Fit

Machine is ‘ready to work’. Hammer and two way lines complete with quick disconnect
ttings as standard. Connections are located close to the tool to reduce hose lengths and
any potential damage. Additional line options are available to further increase machine
versatility. Stick and bucket cylinder hoses are protected by routing them through the boom.

Auxiliary Flow Control

Machines congured with proportional auxiliary hydraulics, include the ability to
adjusttheow for even greater tool control. Especially useful with tools such as angling
ditching buckets.

6

Large operator environment and ergonomic control layout.

Cab Comfort

The Cat 301.7D gives the operator a large comfortable
space in which to work. The ergonomic control
layout, travel pedals and adjustable wrist resets are
engineered to minimize operator fatigue and increase
productivity.

The layout is designed for easy cleaning, minimizing
downtime between jobs.

There is a choice of cab with heater or canopy
available. The canopy offering two sided access
foreven greater on site versatility.

Productive Comfort

Split Front Window

The lower front window section slides into the upper
sectionframe.

Both sections are then raised and stored in the roof
usinga gas assisted mechanism.

This allows the operator to position in front window tosuit
theirvisibility and ventilation requirements with easystorage.

7

Engine and Serviceability

maintenance requirements keep you working.

Powerful Engine

The Cat 301.7D is tted with a 17.9 kW (24.3 hp) gross power engine that is installed at a much lower rated

13.2 kW (17.7 hp). This is designed to reduce engine wear, give cooler running temperatures, with longer
life and lower owner and operating costs.

Excellent Service Access

Daily checks and regular service points including fuel and hydraulic oil ll are easily reached via the
largesteel rear door. The main hydraulic valve and lines are also easily reached through a removable
oorplate and side panels.

The machine has durable steel body panels all around, offering good resistance to impact damage
andhelping to maintain the machine’s appearance and value.
