John Deere’s compact tractor range includes 13 models in six series ranging from 25 to 66hp.
In 2020 the company updated some of the range to meet the latest Stage V emissions regulations in Europe, which are designed to limit ultrafine particulate emissions in all engines above 25hp (19kW).
John Deere’s compact tractors rated at 25hp and below – the 1026R, 2026R and 3025E – already met the necessary standards. Other 2R and 3R Series models above 25hp got a new Yanmar 1.6-litre, three-cylinder TNV Series diesel engine that features a high torque reserve, providing plenty of power under heavy loads.
This uses the latest engine technologies to improve fuel economy, control and accuracy, while also reducing environmental impact as well as operating costs. It features a common rail system (CRS) and an electronic control unit (ECU), which continuously monitors engine conditions and adjusts fuel delivery to ensure optimum performance.
The engine’s new after-treatment system consists of a diesel particulate filter (DPF) and diesel oxidation catalyst (DOC), similar to that used successfully on John Deere’s larger agricultural tractors. This operates automatically to produce lower levels of exhaust emissions and reduced noise levels, and meets all current requirements for Stage V emission standards.
At the top of the John Deere compact tractor range, the 4052M and 4052R have a larger 2.1-litre, four-cylinder engine with DPF. This is the same as the existing engine on the biggest 4066M and 4066R models.
The 3R and 4R Series compact tractors are equipped with a new eThrottle function integrated into the established eHydro transmission. This feature is designed make the tractor quieter and more comfortable to use, as well as more fuel efficient. With the simple push of a button, engine speed is conveniently linked to the foot pedal position so that engine rpm and tractor speed can both be increased as the pedal is depressed.
On selected models, the award-winning Hitch Assist system makes coupling up implements and trailers to the tractor’s rear hitch or three-point linkage quicker, easier and safer. Using this system, external switches mounted on the rear fender allow the operator to move the tractor backwards and forwards at a maximum speed of 12mm/second, and raise or lower the hitch as required.
Other advanced technology features on John Deere compact tractors include LoadMatch, MotionMatch and SpeedMatch operating modes for maximum versatility in a wide range of tractor applications, plus a choice of AutoConnect drive-over rotary mower decks.
