The new John Deere 27D Compact Excavator features reduced cycle times and a long arm option, as well as improved operator comfort with updated controls and a redesigned cab.
Additionally, fuel economy and long service intervals combine to deliver low operating costs.
“This versatile, productive machine is ideally suited to a wide variety of applications,” said Mark Wall, product marketing manager, John Deere Construction & Forestry. “We’ve kept the best features of the C-Series — overall design and great fuel economy — while enhancing numerous features.”
Numerous improvements, include increased operating speeds and 50 percent more drawbar pull and automatic shifting between high and low travel speeds.
Cycle times have been cut by 18 percent, allowing operators to dig more cubic yards per hour.
A new long arm/counterweight option adds approximately 12 in. (30.5 cm) of dig depth and reach.
Powered by a Yanmar 3TNV88 engine, the 27D engine displacement has increased from 1.496 L to 1.642 L. This engine also features a higher torque curve.
The operator’s station provides improvements that enhance operator comfort. The cab is 5 in. (12.7 cm) wider and both hand and foot control levers have been better positioned for easier operating and to provide more room.
Foot room also has increased due to relocation of the speed selector switch and new foldable travel pedals.
The repositioned monitor provides better visibility, as well as two trip meters that can be set to remind operators when service is required.
The cab door now features a bi-fold design that allows the operator to lock it back against the cab in the open position. Factory-installed air conditioning is standard when the optional ROPS cab is ordered. A cup holder also is standard.
Several new features enhance uptime in this machine.
Key among these enhancements is an updated undercarriage that sheds dirt easily and reduces the time it takes to clean the machine.
Improved rubber tracks are harder and have a reshaped core to resist cracking. Additionally, the drive sprocket and track idler have increased in diameter.
The boom cylinder guard has reinforcement ribs that improve strength and reduce the likelihood of cylinder damage. Front hoses in the swing post transition area can quickly be replaced without tilting the cab or routing the hoses to the control valve.
“John Deere compact excavators have always been among the most reliable units on the market. However, we’re continually striving to reduce interruptions and lower daily operating costs,” Wall said.
The 27D has been designed to be easily serviced and maintained. The operator station tilts forward 50 degrees for easy access to the control valve and front side engine components. All service checks can be performed by opening just two covers.
In addition, extended service intervals save both time and money, with a 500-hour interval for engine oil change and greasing, and 2,000-hour interval for hydraulic oil change.
A variety of Worksite Pro buckets — including all of the tools that worked with the 27C ZTS — work with the 27D. Compatible breakers, augers and thumbs also are available. Buckets for the 27D also are interchangeable with the quick-coupler option on the 110TLB and 35D.
