Self-levelling option for the Activa

Self-levelling option for the Activa

Massey Ferguson’s ParaLevel levelling system is now available as an option on the Activa S combines. First seen on the Beta, the technique provides automatic levelling across slopes of up to 20% on the standard 4wd unit and 15% on the optional 2wd specification. Available on the Activa S 5- and 6-walker MCS (Multi Crop Separator) models, the system connects the front wheel hubs to the chassis via a lower triangular-shaped bracket and a link arm above.

MF says the compact design needs no cumbersome assemblies to turn the entire final drive units – it moves only the hubs. This allows the combines to be equipped with wide tyres and still remain within the permitted transport width limit of 3.5m - for example, 800/65 R32 tyres on the MF 7345 MCS ParaLevel. There are two operating modes – transport and work. During transport, the combine lowers and narrows the track width and is capable of a top road speed of 25km/hr. The system raises and lowers automatically in work mode – with a resulting wider track and top speed restricted to 18km/hr.
“It’s surprising how much of our cropped land requires a levelling system to get the most from a combine harvester,” said MF harvesting market development manager Adam Sherriff. “The ParaLevel system not only improves safety but also enables the operator to really enhance performance by reducing losses and improving the sample quality from these hilly areas, rather than making compromises when operating on sloping terrain.”
