Customize your Selective Control Valve (SCV) configurations

• 7, 8 and 9 Series tractors offer a SCV stack aimed at improving performance and aftermarket serviceability. These valves further enable customers to fine-tune hydraulic flow rates and make it easier and more affordable to customize an SCV stack. Now you can switch coupler sizes without having to change an entire SCV slice.

8 Series Visibility packages let you run with confidence, dawn until dusk

• Visibility is more than just lighting. It’s mirrors where you need them, shades for the blinding late-fall and early-spring sun, wipers to help keep all the glass clear, and integrated camera capability. The 7 and 8 Series Tractors let you choose the visibility package that best suits your needs – Select, Premium, or Ultimate with 360-degree light-emitting diode (LED) lighting –so you and your operators can run with all-conditions confidence.

Increase ride comfort during all seasons with 8R suspension options

8R Tractors offer a variety of suspension options to fit your specific field conditions or application. There are three options to choose from on 8R Tractors. An air seat with fixed cab offers a great balance of field and road comfort in an economical package. An adjustable cab suspension with an air seat reduces high-frequency vibrations typically associated with road transport and features three levels of firmness that can be easily adjusted on the fly. The ActiveSeat™ II equipment is typically chosen for field applications to reduce vertical movement and operator fatigue.

• Air seat with fixed cab offers excellent ride quality in a variety of applications
• Two-post cab suspension with an air seat offers exceptional ride for operators spending time on the road
• ActiveSeat II greatly reduces vertical motion experienced in field applications
• Choice of options is available on all 8R Tractors

Independent-Link Suspension (ILS™) primarily helps deliver power to the ground by maintaining proper tire-to-ground contact through a fully independent system. In addition, ILS greatly improves ride over rough or uneven terrain and drastically decreases power hop.

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 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 ap
