Features may include:

Improved Selection Control Valve (SCV) configurations

Beginning with model year 2024, 7, 8 and 9 Series tractors will feature a new SCV stack to improve performance and aftermarket serviceability. The change will further enable customers to fine-tune hydraulic flow rates and more precisely adjust the flow. This change will make it easier and more affordable to customize an SCV stack by switching coupler sizes because previously it would’ve been done by changing an entire SCV slice.

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.
Factory-installed liquid fertilizer capability with ExactRate™ tractor tanks

The 8RX is the only tractor on the market that allows operators to carry fertilizer with factory-installed 3785.4-L (1000-gal.) ExactRate tractor tanks. Built-in wet seal solution pump (requires use of one SCV) easily transfers fluid from tractor to planter. Integrated valve compartment for simple tendering, front or rear fill options are available.

  • One dealer supports the system from tractor to planter
  • Simplified monitoring and control through G5Plus CommandCenter™ display
  • Entry/egress, visibility, and overall machine width un-compromised with fully integrated tanks
  • Ground pressure reduced by 14 percent compared to third-party tanks on wheel tractors
  • Built-in transfer pump, rinse, and agitation for applications beyond planting
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.

  • 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 through 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.
