New tractors set for 2023 debut
Ag machinery maker John Deere has released details of the new 5M models set to hit the New Zealand market next year.
The company has taken the concept of a sub-130hp tractor and re-engineered it from the ground up to meet current and future needs. It has also the well-known Dyna4 transmission on the 5710D and 5711D models.
Featuring a 4.4 litre AGCO Power 4-cylinder engine, the 5710D and 5711D deliver 100 and 110hp respectively, while also offering PTO outputs of 76 and 86hp. The tractors also offer the advantage of meeting Tier 3 emissions compliance, without the need for diesel exhaust fluids or exhaust gas recirculation – thereby reducing operating costs.
The Dyna-4 transmission offers a simple, easy to use gear range with 16 forward and 16 reverse speeds.
This is activated without the need for the clutch, resulting in smooth and comfortable gear shift. The AUTO-Drive ECO mode automatically shifts through the 4 dyna-shift ratios at 1,500rpm. This makes the tractors particularly well suited for transport or light applications.
Manual shifting is as simple as moving the T-shaped transmission control lever forwards or backwards to change up or down through the four ratios. Meanwhile, a change of range is achieved by pressing the range selection button as the lever is moved. In addition, a brake to neutral feature offers operators ease of use when frequent stops are necessary.
Four-wheel drive and diff locks are electronically activated to deliver maximum traction, while the rear axles with internal planetary reductions also incorporate oil-immersed disc brakes to bring things to a stop.
At the business end of the tractor, an open-centre hydraulic system offers a combined flow of 98l/min, delivered to three rear remote valves. The electronically-controlled, Cat 2 three-point linkage offers a useful capacity of 4,300kg. The independent PTO system offers a choice of 540, 540E and 1,000rpm speeds.
The 5700D Global Series features a suspended cab mounted on silent block bushings on the front corners of the cab. This is complemented by spring-assisted shock absorbers on the rear corners of the cab to deliver a smooth, comfortable ride.
Other detail features include a tilting and telescoping steering wheel and an air-suspended swivel seat.
