Boasting new cabs and controls, redesigned track units and increased capacity, John Deere revealed a raft of updates to its combine ranges, at a recent press day.
Alex Heath went to the manufacturer’s UK HQ to see the updated machines...
W Series gets major updates
The smallest combines in John Deere’s portfolio have been refreshed and given some of the features the larger ranges boast.
Cabs on the Finnish-built W330 five walker and W440 six walker are now 15 percent larger, equating to 3.3sq.m of operator space, similar to their big brothers.
In the cab is a new 200 by 76mm touch screen, that runs John Deere’s Automatic Combine Adjustment programmes, bringing the range in line with other manufacturers’ levels of automation.
The software will adjust drum speed, fan speed and concave clearance automatically to suit the type of crop being harvested.
An option on the W330 PTC model is lateral tilt, which affords four degrees of movement for ground contouring and negotiating slopes.
Other hardware updates include a multi-coupler on the header for faster attachment and higher capacity unloading augers.
Speeds on the W330 PTC have increase from 55 litres/min to 75 litres/min while on the W440 the rate is now 100 litres/min, sharing the same system as the W440 PTC. Headers up to 6.7 metres can be fitted to the largest model.
Capacity increases for T Series
Separation area of the T series machines has been increased by 10 percent, affording 6.3sq.m of sieve area.
Feed to the cleaning shoe has also been redesigned. On the six walker machines there are now six auger troughs feeding the six-section cleaning shoe, while on the five walker machines there are the same number of auger troughs, feeding four sections of the cleaning shoe.
John Deere says this optimises the shoe’s capacity and efficiency and ensures an even load.
The 4sq.m separation area on the T Series has been added to, with a 10 percent larger opening on the separator concave and more aggressive rear beater, affording 9.4 percent more throughput in wheat and 6.9 percent in OSR, says John Deere.
Operator and servicing ease has also been improved. Drain banks for hydraulic, pto, engine and transmission oils are now at ground level, while LED service lights can be specified, alongside a new 360 degree LED working light package.
S and T Series combine tracks
Available on the T560 five walker model, both the six walker T Series models and the flagship S700 Series combines is an all-new track unit, for which John Deere has collaborated with Soucy.
Available in 610mm and 762mm widths, all tracks are 2.2m long and boast 1.23sq.m and 1.54sq.m of contact area respectively. This results in a 30 percent larger contact area than previous designs.
The all-new design incorporates five pivot points, said to reduce peak loads of compaction, often found at the rear idlers. New pivots also allow the front half of the track to climb over rough terrain, with up to 180mm of lateral movement, and mid rollers can oscillate to maintain contact over lumps and bumps. John Deere says that operator comfort has been improved by 20 per cent.
Durability is also a major focus of the redesign, said to be improved by 50 per cent. Tracks now feature four steel cores instead of the previous three, while lugs have been made deeper and angled at 55 degrees.
There are no grease points on the track units and service intervals have been extended to 500 hours.
Full hydraulic suspension is standard and a top speed of 40kph is achievable. Opting for the 610mm unit adds £56,885 to the list price, which is less than the outgoing units.
For the first time, John Deere will offer flex draper headers in the UK. The company says it has seen an increase in demand for the header, with its 700FD available in widths from nine metres to 13.7 metres.
The manufacturer says up to 10 per cent greater performance can be expected from its rotary combines, due to head first crop presentation.
Prices for the 700FD range start at £73,283 for the nine metre model rising to £98,135 for the 745FD.
