Increase ride comfort during all seasons with 8RX suspension
8RX Tractors naturally offer excellent in-field ride due to the large footprint and independent movement of the undercarriage systems. A great ride is also enabled by the lack of power hop due to the track system. 8RX Tractors are equipped with a four-post cab suspension and air seat that is specifically designed for and only found on these models. This system reduces high-frequency vibrations typically associated with road transport and allows 8RX Tractors to strike an unmatched balance in ride quality in the field or on the road.
- Four-post cab suspension with and air seat offers an exceptional ride for operators spending time on the road.
- The cab suspension system specifically designed for 8RX Tractors is offered in base equipment.
- 8RX Tractors naturally ride well in the field due to the independent track systems and a large footprint.
-
Match demanding applications with hydraulic options
All 8 Series Tractors come standard with an 85-cc (5.2-cu in.) hydraulic pump. This pump provides up to 227.1 L/min (60 gpm) hydraulic flow. A dual pump option featuring 85-cc and 35-cc (5.2-cu in. and 2.1-cu in.) displacement hydraulic pumps is available for all 8R and 8RX Tractors. The dual-pump system provides a hydraulic flow of 318 L/min (84 gpm), ideal for running at lower engine speeds. At the rear, up to six selective control valves (SCVs) are available with 1.9-cm (3/4-in.) options.
- Single or dual pump options to fit specific producer applications
- Up to 318 L/min (84 gpm) through the dual pump system on 8R and 8RX Tractors
- Options from four to six factory-installed SCVs
- For maximum flow, 1.9-cm (3/4-in.) SCV couplers are available factory and field installed
A power beyond option is available on all models, and a high-capacity take-out oil reservoir (on 8R Tractors only) is also available for high-demand applications.
