Massey introduces 6400 Series tractors

The new 6400 Series tractors from Massey Ferguson introduce a level of power, control and comfort not available in competitive tractors in the 95 to 155 horsepower range. The new Perkins and SISU engines, Dyna-Shuttle transmission and multiple hydraulic power options combine with a new, more spacious cab to get more work out of available hours with less operator fatigue.

Engine design on the 6400 Series starts with a single-piece cast iron block that allows for a narrow frame, tight turning radius and superior visibility. The wastegate turbocharged and air-to-air charge cooled engines meet EPA specifications for Tier II compliance and operate more quietly. The MF 6465 (95 hp), 6475 (105 hp) and 6480 (115 hp) are powered by Perkins 1106 engines with proven Perkins Fastram combustion systems.

New 6.6 ETA SISU engines power the MF 6480 (125 hp), 6490 (140 hp) and 6495 (155 hp), for torque increases of up to 20 percent.

The Dyna-Shuttle transmission with its 4-speed autoshift in each of 8 gears gives operators 15 forward speeds in the working range, 46 percent more working speeds than the closest competitor. The Eco gearbox and EEM translate engine power into road speed more efficiently and quietly, reaching 25 mph at only 1,800 rpm, reducing fuel use and extending engine life.

Speed matching automatically selects the right Dyna-Shuttle ratio according to forward speed when changing gears or range. Efficiencies don't stop there.

MF 6400 hydraulics can be custom designed to take advantage of a rear axle lifting capacity that is the highest in the industry. Three system options combined with options for front-end hydraulic remote valves and the Remote Valve Management System (RMS) make it possible to fit a hydraulic system to operating needs.

The open center hydraulic system supplies 15 gpm at remotes. The Twin Flow system option with its two gear pumps delivers a high flow of 26 gpm and a load sensing operating mode for optimum control and performance. A closed center pressure and flow compensated system offers a maximum flow of 29 gpm, supplying high-pressure oil for steering, remotes and 3-point hitch.

A low-pressure divider valve supplies the PTO clutch, PFA, differential lock and transmission. If there is no demand for high-pressure oil, the system automatically goes to a low-pressure standby mode.

Even the spacious 61 square foot cab exceeds expectations. At 71 decibels, it is the quietest cab in the industry. All major tractor and implement controls are on the right-hand console, while the front console and dash gauges and indicator lights give clear and immediate information on tractor performance and operations.

The exterior lighting touchpad and schematic shows at a glance what lights are on and adjusts lighting patterns at a touch. A systems monitor indicates engaged systems and maintenance needs on a tractor schematic.

Enhanced airflow and ventilation passages provide optimum cooling and heating while the HVAC system automatically recalls selected temperature settings at startup. Even the cab air filter with its outside access hatch is designed for easy maintenance while keeping dust out of the cab.

Long hours in the cab seem shorter thanks to the fully adjustable air-ride swivel seat.

Select the wider deluxe seat option with heated back and automatic weight adjustment.

“These tractors are designed to work hard and smart,” says Rene Boivin, general marketing manager, Massey Ferguson. “An important part of working smart is reducing operator fatigue whenever possible. These cabs do just that, from their smoother ride and improved airflow to convenient control placement. From engine to cab, they get more out of every day.”
