In 2017 Metal-Fach’s portfolio was expanded with a new 4 m cultivator, which thanks to additional accessories may work in a team, in order to double the service width and improve the performance.
U457 may be optionally upgraded with wheel track openers spring-loaded protection. The leveller is installed behind tubular rollers of the cultivator, which effectively levels the field.
The machine has rear tubular roller which rebuilds the soil surface. Additional accessories include side screens, preventing ingress of soil during field works.
The Cultivator U457 is fitted with 36 teeth in 3 rows. Such a solution should satisfy the requirements of most demanding users with regard to the degree of soil opening. The maximum service depth of the machine is 13 cm and the maximum service speed in 15 km/h. The machine requires a tractor with power output at least 130 KM. Also available in variant with 36 mm hitch.
U457 has two rows of tubular rollers dia. 330 mm, as well as a much larger Croskill roller dia. 500 mm, which leaves raster area of the filed and ensures re-consolidation of soil.
Machine weight, in the suspended version, is nearly 2 tonnes.
