The spring steel cylinder rod guard is standard for the bucket, boom and arm cylinder. The use of spring steel not only protects the cylinder rod, but gives resiliency to the guard itself.

Superior durability

Dozer cylinder rod guard protects dozer cylinder from damage.

Back�ll dozer blade has wear-resistant cutting edge.

The frame corners are reinforced with thick cast iron.The side cover has thicker plate for higher resilience.

Durability

Work light is set under the boom to minimize potential damage during operation.

Compact, Tough PerformerMini excavators are widely used at sites where space is limited, such as residential

areas and industrial operations. Users want big power in a small machine, stable

operation, rugged construction and

durability to reduce downtime. The SK17SR combines a compact design with long

digging reach for e�ciency, maneuverability and durability to ensure a long working

life.

Max. digging depth :

7 feet 3 inches (2,200 mm) Swing speed : 9.5 rpm

Compact

Performance

Tail swing radius overhang is 0 inches with the crawler s ide frames fully extended, so you can w o r k i n t i g h t p l a c e s safely and e�ciently.

Ultra-small rear swing design with zero overhang

During a right boom swing, the left front frame does not extend past the crawler shoes, so you can smoothly dig along walls.

Excellent side ditch digging along walls

The front minimum swing radius is a short four feet, six inches at full boom swing that allows for digging, swinging, and loading even in tight spots.

Digging depth of seven feet, three inches puts it at the top of its class.

Smaller front minimum swing radius

Digging depth at the top of its class

Powerful swing torque and top-class swing speed deliver shorter cycle times.

Reliable swing power, faster working speed

Straight Travel circuit allows you to drive in a line, even while operating the boom.

Straight Travel

Adapt to job conditions by changing the dozer blade width. The dozer blade wings fold in and out and are securely fastened with a retainer pin.

Easy change of dozer blade width

The hydraulic retractable side frames are strong and durable, as well as self cleaning. They retract to a narrow 37 inches for those tight areas and extend to a solid 50 inches for stability.

Do not attempt to lift or hold any load that is greater than these lift capacities at their speci�ed lift point radiusand heights. Weight of all accessories must be deducted from the above lift capacities.Lift capacities are based on machine standing on level, �rm, and uniform ground. User must make allowancefor job conditions such as soft or uneven ground, out of level conditions, side loads, sudden stopping of loads,hazardous conditions, experience of personnel, etc.Arm bucket pin is de�ned as lift point.The above lifting capacities are in compliance with SAE J/ISO 10567. They do not exceed 87 % of hydrauliclifting capacity or 75 % of tipping load. Lifting capacities marked with an asterisk (*) are limited by hydrauliccapacity rather than tipping load.Operator should be fully acquainted with the Operator’s and Maintenance Instructions before operatingthis machine. Rules for safe operation of equipment should be adhered to at all times.Lift capacities apply to only machines as normally equipped by KOBELCO CONSTRUCTION MACHINERY CO., LTD.
