John Deere Unveils New Engines at ConExpo Las Vegas
The recent ConExpo construction show held in Las Vegas, said to be the largest exhibition of its type in the world, saw John Deere Power Systems (JDPS) preview two new mid-range industrial engines.
The 6230R and 6250R models will use a 6.8L PowerTech PSS engine to deliver 230 and 250hp respectively, using dual turbochargers, with DPF and SCR to meet Tier 4 emission regulations. Using Intelligent Power Management (IPM) the flagship 6250 model will deliver up to 50hp boost to make the dial hit 300hp when required, while tipping the scales at 9.3 tonnes and allowing a maximum operating weight of 15 tonnes.
With service in mind, these new tractors are offered with 750-hour engine oil, engine filter and fuel filter service intervals, while a lifetime DPF and a 2-3% SCR fluid inclusion rate should help reduce servicing costs.
An upgraded AutoPowr transmission is now said to offer 100% mechanical effort at 3.5km/h for heavy draft work, 11km/h for top work, 22.5km/h for heavy haulage and 47.2km/h for high-speed road travel. At maximum speeds, 50km/h comes up at 1630rpm, while 40km/h tilts the dial at a lowly 1300rpm, and will result in real savings in fuel use.
In the cab, an all-new CommandPro joystick is said to combine ergonomics with versatility, can allow a move to top speed with a single push, and offer a choice of 11 programmable buttons to control the PTO, SCVs and guidance functions.
Hydraulics are taken care of by a PFC system delivering up to 160L/min flow at 1500rpm, once again helping to save fuel, and can be specified with up to 6 SCVs.
Rear linkage capacity is rated at 10.4 tonnes, and a healthy 5t can be lifted up front.
Operator comfort is taken care of with the new HCS Plus, hydro pneumatic cab suspension system, which helps isolate noise and vibration, and up front a self-levelling version of JD TLS is fitted. Called TLS Plus, the system automatically adjusts sensitivity and suspension effort to help deliver 10% more power to the ground, and it works with the three-point linkage system to eliminate power hop.
Also in the package is a variable ratio steering function which can be accessed through the Command Centre to adjust steering ratios to tasks encountered.
Complementing the hardware, a new connectivity package features My JobsConnect and JobsManager to give operators real-time views of work as it is done, and can combine with navigation and logistics optimisation for more productive working days.
Expect to see these new tractors arriving in New Zealand in August/September.
