NEW John Deere Series of Tractors
By Steve Mitchell
5020 Series tractors feature full frame design
The new range consists of three models for both the agricultural and amenity markets, for use by farmers, growers, contractors, Groundsmen, local authorities and public utilities. Compact, manoeuvrable and with excellent all-round visibility, they are particularly suitable for use in and around buildings and in other confined spaces, and are also ideally suited to pulling large gang mowers and trailers for amenity grass mowing and general haulage duties.
Designed and built at John Deere's Mannheim tractor factory, the 72hp 5620, 80hp 5720 and 88hp 5820 fit into the range between the existing 5010 Series standard and narrow models from 53 to 80hp, and the 6020SE range from 75 to 110hp. They also borrow many of their advanced technology features from the higher horsepower 6020 Series tractors.
The new 5020 Series tractors incorporate John Deere PowerTech four cylinder constant power engines with maximum power ratings of 74, 83 and 91hp respectively, and up to 34 per cent torque reserve. They also meet the requirements of the latest Tier 2 emission levels legislation.
The full-frame design on these tractors combines a low overall weight of 3.7 tonnes and compact dimensions with a high payload capacity. This allows larger, heavier implements to be carried without placing extra stress on the engine and drivetrain components, which can therefore concentrate on transmitting the power.
This approach has led to the development of lighter, stronger, more versatile tractors with better weight distribution; this is 40 per cent on the front axle and 60 per cent on the rear as standard, which is ideal for front loader work. The design also means there is no need to fit expensive sub-frames for the loader, which is bolted directly to the steel frame, and is fully compatible with the optional front hitch and pto.
John Deere's popular PowrQuad 40kph 16-speed transmission with Perma Clutch II is fitted as standard, and includes four powershiftable speed ranges and a left hand power reverser with neutral, for easy shifting under load without clutching.
Automatic speed matching on the optional PowrQuad Plus transmission, which features single lever shifting, allows the correct gear to be chosen when shifting though the fully synchronised ranges. An additional 16 speeds are optionally available for both transmissions, giving a minimum speed of 1.5kph (less than 1mph).
The flat floor 5020 Series cab is the most spacious in this class, and provides excellent all-round vision, especially for loader applications, with a glass roof hatch, curved rear corner window and rear implement window.
It also incorporates comfortable suspension seating, a foldable passenger seat and has a low noise level of 75db(A). Total height of the tractor on 16.9R-30 rear tyres with the standard cab is 2.545m, or 2.495m with the low profile version, and turning radius is 3.95m.
Additional advanced technology features on the new 5020 Series tractors include a high capacity pressure compensated hydraulic system with load sensing, and a 56 or optional 65 litre/min pump. The HMS II headland management system as featured on larger tractors in the John Deere range is available on PowrQuad Plus models, and the category 2 three point hitch has maximum lift capacities of 3.7 and 4.2 tonnes, depending on model, with electronic hitch sensing and hitch dampening.
Standard specification also includes electro-hydraulic on the move engagement of four wheel drive, a 131 litre fuel tank and a 500 hour engine service interval for reduced maintenance costs. UK base prices are £29,109 for the 5620, £30,987 for the 5720 and £32,864 for the 5820.
