AGCO RT series tractors, equipped with the new 6.6 litre AGCO engine, run quieter and use less fuel, says the company. The new engines also expand the power range available in the RT series from 100 to 155 horsepower with the RT100A, RT120A, RT140A and RT155A (model numbers designate PTO horsepower output). RT100A and RT120A also offer the option of the new Auto-6 transmission with six powershifts in four ranges of clutchless shifting, resulting in 24F and 24R speeds.

The new engine runs quieter, thanks in part to its solid one piece design, but also due to its lighter connecting rods that produce less vibration. The variable speed fan ensures optimum engine temperature, reduces fuel consumption and ensures easier start up, quicker warm up and overall improved efficiency.

All four new RT series tractors are available with PowerMaxx CVT (continuously variable transmission) for maximum power and infinite travel speed selection. All controls are ergonomically placed for easy access. When PowerMaxx CVT RT tractors are also equipped with the optional front suspension, they provide up to 50km/hr (32mph) transport speed. In addition, RT100A and RT120A tractor models are available with the new Auto-6 transmission with 24 forward and 24 reverse speeds. The Auto-6 offers operators a choice of six power shift ratios that can be shifted under load without clutching within four auto-select ranges. Shifting between the four ranges is also clutchless. The left hand control lever on the steering column provides forward and reverse direction control and easy selection of the desired powershift ratio. The right hand, console mounted, power control lever allows the operator to manually select powershift ratios or one of four gearbox ranges.

A rotary dial controller provides over-speed protection with manual shifting or 'speed matching' powershift selection after a manual range change. When an operator uses the dial to select 'road' or 'field' modes, the operator makes range selections manually while the transmission changes the powershift ratio. In road mode, powershift ratio and gear range are selected automatically. The Auto-6 transmission allows the operator to pre-select forward and reverse starting gears. The operator also can adjust the shuttle clutch to provide more or less aggressive direction change. Even more gear options at slower speeds are available with the 4:1 creeper option.
