John Deere 1470 and 1570: two new conventional combine harvesters

The new John Deere 1470 and 1570 combine harvesters replace the John Deere 1450 and 1550 models.
The 1470 is a five-walker machine with 204 ch, while the 1570 is a six-walker machine with 262 ch.

These models are fitted with a conventional threshing cylinder 610 mm in diameter. They can be ordered now for the 2010 harvest season.

According to the manufacturer, several improvements have been made to ease maintenance and increase the reliability and durability of the John Deere 1470 and 1570. The feeder house has been redesigned to provide a more even flow of material from the cutting platform.

It is longer and therefore positions the header well ahead of the machine, so the operator enjoys good visibility without leaning forward.

Changes have been made to the steering, the electrical system, the sieve drive and the chopper to improve the operator's environment and increase productivity. New headlights improve light distribution for night work.

The grain tank capacity has been increased to 6800 litres on both models.

The John Deere 1470 and 1570 combines have hydrostatic transmission.

The 600R series headers range from 4,3 metres to 7,6 metres in width. A new hydraulic system would improve response time and increase the header lifting capacity and reel speed.

According to John Deere, these machines would offer a high threshing capacity thanks to their high-inertia 610 mm diameter cylinder combined with a generously sized concave.

Electric adjustment of the concave is standard. The cylinder rotation speed can optionally be reduced down to 150 tr/min to maximise grain separation.

The cleaning area would also be generously sized, and grain losses on slopes would be reduced thanks to the SlopeMaster system.

A new feature of the optional straw chopper on the 1470 and 1570 is that it activates automatically when the windrow/chopping lever is switched. The optional chaff spreader is also adjustable from the cab.

The cab would offer excellent visibility in all directions, a mechanical seat as standard or an air-suspension seat as an option, a multifunction handle, performance monitors in the corner of the cab and a particularly efficient air-conditioning system. The InfoTrak dual-screen console lets the operator customise the display to view two functions at once and so monitor machine performance more closely.

The optional HeaderTrack system automatically controls cutting height and ground following when working on side slopes or uneven ground, at night or in lodged crops.

These combines are also equipped with a hydraulic reverser to clear blockages and an electro-hydraulic multi-coupler that allows the platform to be connected quickly in a single operation.
