Kubota introduces new M5 Series utility tractors

20 August 2015

Kubota Tractor Corporation announced the launch of new M5-Series utility tractors. The series offers two models—the M5-091 and M5-111—both available with two- or four-wheel-drive. The M5-Series features an Ultra Grand Cab II with expanded space and enhanced visibility.

The M5-091 and M5-111 tractors are powered by four-cylinder, turbocharged 76 and 89 hp Kubota engines, respectively. The engines—certified to the US EPA Tier 4 emission standards—are equipped with both diesel particulate filter (DPF) and selective catalytic reduction (SCR) technologies.

For the first time, both the DPF and SCR are located inside the hood—said Kubota—increasing visibility around the tractor. In many nonroad tractors, the DPF/SCR unit is located outside of the engine compartment, creating potential concerns with reduced visibility for the vehicle operator.

Many diesel engines also meet Tier 4 emission standards without the use of particulate filters—about 50% of nonroad engine families certified to the Tier 4 standards do not use a DPF—raising concerns among clean air authorities. The California ARB has stated that off-road engines operating without a PM filter, albeit meeting all applicable standards, do not represent the cleanest, best available technology. It is unclear—said the agency—if engines that are not originally equipped with PM filters will provide a high level of PM control over their in-use lifetime and over real-world duty cycles.

The M5-Series offers multiple transmission speeds—transmissions are available in 8-, 12- and 24-speed options. A hydraulic shuttle provides smooth-shifting between forward and reverse by use of a single lever, eliminating the need to engage the clutch to change directions.

Kubota’s new M5-Series utility tractors will be available at authorized Kubota dealers in the North American market starting in August 2015.
