One driving force behind a lot of new product introductions in the past year, has been the move to meet more stringent emission standards for diesel engines. Bobcat has been dealing with that process too, and a lot of that work is now coming to market in new products. The company has announced the move to a 3.4-liter diesel for it's 700- and 800-frame-size loaders, which meet Final Tier 4 standards without the need for a diesel particulate filter. That eliminates the need for the regeneration process and routine filter cleanings for these machines. The models that get the new engine include the S750, S770 and S850 (shown) skid-steer loaders; and the T750, T770, T870 compact track loaders; and the A770 all-wheel steer loader.
The Bobcat approach to meet emission standards includes using a high-pressure common-rail fuel injection system, cooled exhaust gas recirculation, diesel oxidation catalyst and selective catalytic reduction. While the machines don't have a DPF that needs attention, users will have to start using diesel exhaust fluid with these machines. The fluid, called DEF by most people, is already commonly used in on-road trucks and other diesel vehicles. In fact, all final tier four machines above 175 hp are now using DEF as an add-in fluid to meet emission standards.
All new 700-and 800-class machines rated at 75 hp and above have an updated display panel in the cab that includes a DEF level indicator to keep you informed about how much of this fluid is available. An added feature is an SCR error icon which lights up when the DEF tank is at 25% capacity.
The new machines feature more cooling vents, as well as electric air inlet fans in the loader tailgate to help keep the engine compartment cool. And there are added vents to allow warm air to exit the engine compartment. Horsepower ratings for the line remain the same as their predecessor, with the exception of the T870, which increases to 100 hp. This is the company's first track loader with 100 hp.
