John Deere’s high-horsepower 7R, 8R and 9R Series tractors will feature on the company’s working demonstration area at Tillage Live in the UK (Lincolnshire) in September.
The top-of-the-range 9620RX four-track tractor is making its Tillage Live debut. It boasts a 620hp Stage IV 15L Cummins QSX engine, an e18 transmission, articulated steering, cab suspension and optional Active Command Steering (ACS) for improved manoeuvrability.
AutoTrac guidance and JDLink Connect information management systems are also available. Track widths are 76cm (30in) as standard or 91cm (36in) as an option.
The latest 9RX range, which is of limited practical appeal here in Ireland due to its size, is designed to provide improved ride quality. The undercarriage incorporates a positive-drive track system that, according to John Deere, delivers more power to the ground.
John Deere’s 7310R tractor, which will also be at the event, set a new total fluid efficiency record of 258g/kWh for high-horsepower Stage IIIb and Stage IV tractors after undergoing the ‘Powermix’ test at DLG’s (the German Agricultural Society’s) centre in Germany back in 2014.
John Deere’s engine technology combines a diesel exhaust filter, series turbochargers, selective catalytic reduction (SCR) and a higher fuel injection pressure to achieve Stage IV / FT4 compliance.
More recently, the 400hp 8400R tractor set three new world records for fuel efficiency, in the field and on the road, and maximum drawbar performance at DLG’s test centre.
It, says John Deere, beat its nearest competitors by almost 23% in drawbar performance and lowered the combined fluid consumption figure for field work to only 247g/kWh.
This apparently translates into 6% higher pulling capacity and a reduction in fuel consumption of up to 2% compared to the previous top-of-the-range 8370R model.
Powered by a new John Deere 9L Stage IV compliant engine and featuring an e23 transmission with Efficiency Manager, the 8400R delivers up to 450hp with Intelligent Power Management (IPM). This tractor is also fitted as standard with JDLink telematics, including remote display access (RDA) and wireless data transfer (WDT) linked to the MyJohnDeere.com website portal.
Also on display at Tillage Live, the existing 750A All-Till seed drill is available in 3, 4 and 6m versions. This drill has an Accord air seeding system and is designed with “large clearances” for no-till drilling into stubble, working after minimum or conventional cultivations, and single-pass operation for grassland and rough pasture renovation.
