John Deere has announced a number of updates to the company’s comprehensive compact tractor range for 2020, which includes 13 models in six Series from 25 to 66hp.
The main change is prompted by the latest Stage V emissions regulations in Europe, which are designed to limit ultrafine particulate emissions in all engines above 25hp (19kW). Ultrafine particulates are less than 0.1 microns in diameter, which is 700 times smaller than a human hair.
John Deere’s compact tractors rated at 25hp and below – the 1026R and 2026R, which remain unchanged, and the new 3025E – already meet the necessary standards. Other 2R and 3R Series models above 25hp get 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 new 4052M and 4052R receive 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, which remain unchanged, while several of the smaller 2R and 3R Series tractors are also given new model numbers.
In addition to the new engine, the 3R and 4R Series compact tractors will be 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.
The latest 4R Series models can also now be equipped with a StarFire satellite receiver and AutoTrac Universal automatic steering system. This is designed to help operators achieve higher levels of accuracy and input cost savings when working with implements such as amenity turf sprayers, seeders and spreaders.
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.
Cabbed versions of John Deere’s new range of compact tractors for 2020 can be ordered now from UK & Ireland dealers, while open operator station models will be available from October.
