Excavators
Uncover Profitability with High Performance Komatsu Compact Excavators.
When you buy MMD Equipment, you get much more. The cornerstone of a great buying experience is a high-quality product. But to maximize your productivity and income, you need more than just a machine. That’s why MMD Equipment is committed to adding value in every aspect of our business relationship. With every MMD Equipment product you purchase we stand behind our PROVEN PERFORMANCE, FLEXIBLE FINANCING, SERVICE and EXPERIENCE.
COMPACT HYDRAULIC EXCAVATOR OPERATOR ENVIRONMENT Large Entrance and Foot Space • The two–post canopy design allows the operator to enter and exit the machine from either side with ease. Also, by automating the travel speed, we have eliminated a foot pedal thus adding foot space.
Reclining Suspension Seat • Lessens operator fatigue.
Joystick Controls • Allows for continuous, comfortable operation.
Excellent Visibility • The operator can maintain excellent visibility at all times with no forward obstructions and minimal rear obstructions.
Pattern Change Valve • Whether you are comfortable with excavator or backhoe control patterns, you can easily and consciously change from one to the other. The readily accessible Pattern Change Valve allows easy personalization of operator controls.
PRODUCTIVITY FEATURES Zero Tail Swing • The machine is transformed to zero tail swing by simply removing the additional counterweight.
CLSS HydrauMind Hydraulic System • Even when multiple functions are operated simultaneously, the pressure-compensated CLSS system ensures each actuator works according to its control input, regardless of the size of the load. This gives the operator precise control at all times.

EASY MAINTENANCE
Tilt-Up Operator Compartment The operator’s compartment and floor tilts forward for easy access to hydraulic components. This function is not required for daily inspection, however, it is possible to perform service quickly when required.
Larger Diameter Swing Pin It has high durability and maintains suitable clearances between pin and bushing after long term operation.
Built-In Hydraulic Hoses Are protected from debris.
Fully Opening Engine Hood and Side Hoods Allows easy access for periodic inspection.

500 Hour Maintenance Interval To reduce maintenance costs and increase productivity, our excavators are designed to have extended lubrication intervals for equipment bushings and swing circle plus, extended engine oil replacement intervals.
High Strength X-Track Frame X-track frame deters mud and debris build-up saving the operator valuable time when cleaning the machine.

OPTIONS
Breaker Arm Easily converts from bucket to hydraulic breaker configuration since breaker is stored inside arm when not in use. (Available only on the PC09-1.)
Road Liner Mechanical Quick Coupler Exchanges buckets and attachments easily.
Replacement is fast, easy, and cost efficient as individual shoes are replaced when damaged or worn instead of replacing the entire track. (Only available on Models PC27MR-2, PC35MR-2, PC40MR-2, PC50MR-2 and PC78MR-6.)
Large Operator’s Cab The cab offers large operator foot space and is available as an option on Models PC20MR-2, PC27MR-2, PC35MR-2, PC40MR-2, PC50MR-2. This ergonomically designed feature helps reduce fatigue and increase focus on the job. The large rear glass
