Precise harrow technology

Cura 6-15 ST

HORSCH LLC. Products Hybrid Farming | Cura 6-15 ST

The frame

combines longevity and running smoothness

  • The closed frame design made of rectangular bars guarantees high torsional stiffness and is still light and solid.
  • Pivoting at the wing sections allows for:
    • More comfortable turning due to slightly raised side wings
    • Excellent adaption to hilly terrain due to floating position in working position.
  • Maximum frame height of 450 mm allows for harrowing high crops
  • Position of the support wheels at the frame can be adapted to the spacing of the row crops (25, 30, 45, 50, 70, 75 cm)
  • Simple and solid depth adjustment of the support wheels
  • The two middle rear support wheels can be variably adjusted to the track width of the tractor, max. 2.50 m
  • With scaper for rear support wheels, following harrow as an option
  • Working widths 6 m, 9 m, 12 m, 13.5 m and 15 m
  • Mechanical tine retraction in the middle segment for Cura 9 and 15 ST for a reduced transport height

Cura 6 and 9


  • Up to 7 support wheels can be used
  • One-side folding
  • 3-part folding

Cura 12, 13.5 and 15


  • Up to 11 support wheels can be used
  • Reduced working width by both-sided folding of the outside wings
  • 5-part folding to 3 m transport width
  • Cylinder of the 180° folding is placed inside the frame, derived from the well-proven frame concept of the tillage sector

Cura ST

SIMPLY EFFICIENT

  • Excels due to acreage performance and stability
  • Sturdy and at the same time compact design
  • Precision in most different conditions
  • Simple handling
  • The field of application ranges from very light harrowing in small crops to the aggressive breaking of crusted soils

Fine to aggressive

INDIVIDUALLY SUSPENDED TINES WITH DOUBLE SPRING

The spring

  • Tine pressure can be adjusted gradually hydraulically
  • Option: infinitely variable adjustment with scale
  • Springs are attached above the frame and allow for a gentle harrowing of high populations
  • The double spring guarantees a working range of 300 g to 5 000 g and allows for a fine, blind harrowing and also for working very aggressively
  • Almost constant tine pressure for different tine positions allows for working on the contours, e. g. potato ridges

The tine

  • Available as harrow tine standard 100° or harrow tine mulch seed 125°
  • Tine length in the wear area: 130 mm
  • Tines are connected and suspended individually
  • Tines are arranged in steps on 6 bars for a better clearance
  • Laterally stable due to large bearing
  • Harrow tines with a diameter of 8 mm
  • The tine position is adjusted via height-adjustable support wheels
  • Cranked tine for a force transmission in the middle
