New Caterpillar more powerful; comfortable; efficient

The new D11T and the D11T CD, the latest iterations of a range first introduced in 1986, deploy an 850-net horsepower (634kW) Cat C32 engine that meets U.S. EPA Tier 4 Final emissions standards, suitable for areas that need a high degree of emissions control. The C32 engine uses a NOx reduction system, which works by trapping a small volume of exhaust gas, which it then uses to cool its combustion chambers and retard formation of nitrogen oxides. It also conditions exhaust gases using a diesel oxidation catalyst.

A new oil-to-air hydraulic-oil cooler is designed to be more efficient and quieter, while more resistant to corrosion.

Using a new Enhanced Auto Shift system automatically selects optimal reverse gear and engine speed based on load and desired ground speed in an effort to conserve fuel.

The D11T?s cab has been refitted with single-joystick blade control, finger-tip steering, automatic climate control and even heated and ventilated seats. An automated blade assist control simplifies blade-pitch positions while a dynamic inclination monitor provides info on tractor pitch angle. A sound-suppression package is available on request.

Its improved performance is matched by its safety and serviceability, with an ?OK-to-Start? feature that automatically checks critical fluid levels. An innovative ?operator presence system? decreases the chance of the machine moving when the operator?s getting in and out by locking out the power train and hydraulics.
