John Deere Australia and New Zealand production system manager, Stephanie Gersekowski, said the 9500 was part of a redefined SPFH line up, which includes the reintroduction of the 9600 and a new horsepower level and engine for the 9700.

The MY23 8000 Series will remain the same, however, horsepower has been increased via an engine upgrade for the 8200.

The 9500 has a rated 515kW (690hp) engine with maximum power of 563kW from its 18 litre engine while the 9700 is rated at 563kW from its V12 engine.

"The new 9500 is one of three models offering increased power and throughput in 2023, delivered through John Deere's new JD18X engine which reduces revolutions per minute, while decreasing fuel and oil usage to drive further efficiency gains during operation," Gersekowski said.

The 9500, as well as the 9600 and 9700, also comes equipped with HarvestMotion PLUS, an advanced feature synchronising engine speed with crop flow and power needs to maintain consistent crop throughput at low engine revs.

"HarvestMotion PLUS delivers an additional 18, 27 and 48kW of power across the 9700, 9600 and 9500 respectively," she said.

"This provides farmers and contractors with 10 per cent more productivity and 10 per cent less fuel usage per tonne harvested.

"A new spout design will become standard across the complete 9000 Series," she said.

"The spout has a longer, optimised contour to create increased visibility and more service openings, making the machine easier to service to help farmers and contractors maximise their machinery uptime."
