Blade
The innovative 'SIGMADOZER' reduces digging resistance for smooth material roll and increased blade load, hence increased productivity. The new blade linkage system ensures more visibility and reduces lateral sway. 

RIpper
A new ripper design increases visibility and provides a wider movement range of operation, this includes a very high lift.
