This is the Kuhn Stronger 4000 SP sprayer

The Trimble TMX-2050 virtual terminal in the new-design cab of the Kuhn Stronger 4000 has a 308mm (12.1in) touch screen and uses an Android-based operating system enabling user customisation.

It comes with an integrated GNSS receiver and camera feed (with support for a second), includes Isobus compliant communications, and can connect to a telematics data collection system for remote monitoring, machine operation analysis and farm records.

A Trimble TMX-2050 virtual terminal with Android-based operating system is a standard fitment in the sprayer’s new cab.

The Stronger 4000 is built by Kuhn Montana in Brazil and joins the existing Stronger 3000-litre (792 gal) sprayer, offering greater capacity and output, plus ultra-high clearance of 1.8m (6ft) permitting late season spraying in corn and similar crops.

Emission control

The new hydrostatic drive machine has a 4000-litre (1056 gal) stainless steel tank and a choice of 36m and 40m (118ft and 131ft) booms constructed from extruded aluminium, which are said to combine high shock and corrosion resistance in addition to relatively low weight, and are available.

Both Stronger sprayers are powered by a 7.2-litre MWM MaxxForce Turbo Intercooler diesel engine, but for the new model this is uprated from 220hp to 280hp.

High clearance of up to 1.8m (6ft) allows for late-season spraying treatments in corn and other tall row crops.

Emissions control equivalent to European Stage IIIA make the machines suited to big farms in Russia and other CIS countries, and other markets with this or lower levels of emissions regulation.

The 6-cylinder power unit drives through a new Eco Drive 4×4 hydrostatic 4-wheel drive system with electronic control to regulate engine revs for best fuel economy, and there is electronic traction control at each of the hydraulic wheel motors.
