The Czech manufacturer says it listened to customer feedback in developing the third generation of the Ontario disc cultivator. Currently available in working widths of 5.0m and 6.0m, the shorter design is said to provide improved manoeuvrability, especially on headlands.
The mid-mounted axle results in a better spread of the machine weight and the space between the two rows of discs and rollers helps prevent blockages. The company says that bringing the centre of gravity closer to the drawbar prevents the machine from swaying at faster working speeds and results in an even working depth.
Mounted on maintenance-free bearings, standard disc diameter is 510mm (560mm optional) and the discs are secured by rubber silent blocks. Standard equipment includes road lights axle brakes and the 10/75-15.5 support wheels are said to be wide enough to run on soft ground.
Working to a maximum depth of 12cm, tractor power requirement is a minimum of 200hp (Cat III linkage) and the two-piece frame on the Ontario 500 and 600 folds to below 3.0m for transport.
A wide range of rollers are available and additional options in the pipeline include a flexible skid or cutting roller in front of the discs. An upgraded version of the Ontario 800 (8.0m) is also in development.
The Ontario is brought to the UK by Northumberland-based Dales Agri Sales Agency and is available in Ireland through DH Farm Machinery.
