Massey Ferguson Adds ParaLevel Option for MF Activa S Combines

Massey Ferguson is introducing its ParaLevel leveling system to its MF Activa S range of combines. First seen on the MF Beta range, this system is now available on the MF Activa S 5- and 6-walker MCS (Multi Crop Separator) models. It uses parallel linkage for machine leveling whilst allowing the fitment of wider tires but maintaining the important 3.5m width for road transport.

The Massey Ferguson ParaLevel system provides automatic leveling across slopes of up to 20% on the standard 4WD unit and 15% on the optional 2WD specification using a parallel linkage. The compact and clever system connects the front wheel hubs to the chassis via a lower triangular-shaped bracket and a link arm above – forming a parallelogram-shaped linkage.

The neat design means that there is no need for cumbersome assemblies to turn the entire final drive units – it moves only the hubs. This offers the distinct advantage of allowing the combines to be equipped with wide tires and still remain within the permitted transport width limit of 3.5m - for example, 800/65 R32 tires on the MF 7345 MCS ParaLevel. Also as the combine rises, stability increases because the parallel linkage has the effect of slightly widening the track width.

A solid-state, electronic pendulum, ensures a fast, smooth and precise leveling response to changing terrain. The system has two operating modes: In ‘Transport’, the combine lowers and narrows the track width and is capable of a top road speed of 25km/h. In ‘Working’ mode, the system raises and lowers automatically – with a resulting wider track and top speed restricted to 18km/h.

“It’s surprising how much of our cropped land requires a leveling system to get the most from a combine harvester. 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.”
