Lexion Terra Trac in a class of its own

There were plenty of big toys at Dowerin fields days, including the Claas Lexion 750 Terra Trac.

Shown in WA for the first time last year, the Terra Trac is unique in the market - the only trac system on a combine.

Claas Harvest Centre operations manager Steve Reeves said the machine was ideal for farmers looking to save on road travel.

"It can go 40km/h on the road. Farmers make their money in the field," Mr Reeves said.

Travelling speed of the Terra Trac is also a drawcard for those looking to save time. The system allows the Lexicon to be taken from field to field faster than any other combine harvester, with greater driving safety, comfort and outstanding handling in lanes.

"Fifty per cent of our sales this year have been from tracs," Mr Reeves said.

"The trac system is an alternative to dual wheels.

"The advantage is it gives the machine better stability. A lot of people think of tracs as a bone shaker design but the suspension system gives the machine smoother operation."

The redesigned Terra Trac system with independent suspension for all its components (drive wheel, land wheel and support rollers) reduces shocks to the carriage and machinery, increases operator comfort and ensures better stability on curves.

Better adaptation to ground contours, uniform stubble height, less equipment stress and 30 per cent lower ground pressure peaks also make the difference clear.

Automatic levelling is another special feature of the system and the hydropneumatic suspension can be raised or lowered during operation by filling or emptying the hydraulic cylinder.

The drive wheel, land wheel and support rollers are counter-directionally pivot-mounted and hydraulic cylinders with integrated pressure reservoir support the suspension.

The result is automatic levelling for improved stability on curves.
