Kubota Australia’s range of cultivation tools, including compact speed discs, power harrows and tine cultivators are now available at Bertoli’s Shepparton.
Ideal for incorporating straw and crop residue, Kubota’s CD series speed discs offer farmers and contractors a versatile machine that can perform shallow or deeper cultivation, as well as good cutting and mixing actions to incorporate cereal or corn residues and green crops.
The CD1000 Series comes in rigid working widths of 2.5m, 3.0m and 3.5m, and the speed discs are 15 per cent lighter than the heavy duty CD2000 Series models which come in working widths of 3m, 3.5m and 4m.
Three linkage-mounted folding models are available for wider working widths to allow for narrow road transport, with working widths of 4m, 5m and 6m available.
Four trailed versions of the CD2000 are available in 4m, 5m, 6m and the beast of the range, the 7m CD2700T. CD1000 versions have 520mm x 5mm discs while the CD2000 versions have 600mm x 6mm discs.
Kubota Implements product manager Mark Allott said both ranges offered sturdy frames that could be fitted with heavy rollers to level the ground tilled by the discs.
‘‘CD speed discs have a robust disc arm that withstands high stress at fast working speeds of up to 20km/h. Strong 35mm shafts each carry two rows of maintenance-free bearings and have five lip seals that prevent any contamination from soil or dust,’’ he said.
‘‘The discs are heat-treated to harden the steel to increase lifespan.
‘‘Because they are conical discs, they work at an aggressive angle. This means CD1000 and CD2000 speed discs deliver excellent penetration, even in dry conditions.
‘‘They completely cut the ground and slice the stubble abolished and mix it on the surface to provide good emergence so that you can control weeds and volunteer cereal seeds.’’
The working depth of the discs are adjusted manually on the CD1000 and hydraulically on the CD2000 series via the rear roller.
Standard equipment for both CD1000 and CD2000 includes adjustable lateral side deflectors to control the soil flow and provide a perfect level finish.
The standard following harrow is positioned just in front of the roller and cuts the flow of the soil and levels the surface, while the finger harrows allow adequate soil flow without a big power demand.
Working depths can be adjusted from the tractor cab, as can hydraulic folding and unfolding into and out of transport mode.
