Said to be ideal for controlled traffic systems, the wider stance also provides increased stability on hilly land, more space to clean the inside of the tracks, and easier access for maintenance and service.
A 9RX equipped with a rear linkage must select the 2.21m track spacing option with the 76.2cm tracks, as the wider 3.05m track option is not compatible with a rear hitch.
The 9R, 9RT and 9RX are also available with the hydraulic Intelligent Power Management (IPM) option, which boosts tractor performance when operating implements requiring continuous hydraulic power.
Also compatible with the 2015 9620R and 2016 9620RX, IPM provides an extra 25hp in gears five to 18 and 50hp in gears one to four. It requires a 435lit/min dual hydraulic pump and is not compatible with a rear linkage.
A Generation 4 CommandCenter software update is also included on 2019 9R, 9RT and 9RX models.
