STXV, New Holland's range of vibrating tine stubble cultivators

Stubble cultivation is a key step that marks the end of one harvest cycle and the start of the next. The STXV range is designed for shallow stubble cultivation or deeper work, from 5 to 25 cm, at working speeds between 8 and 12 km/h, producing a homogeneous mix thanks to the vibration of the tine.

A complete range, with mounted and trailed models up to 7.00 m working width
The New Holland STXV stubble cultivator range is available in mounted or trailed versions.

The mounted models come in a fixed rigid version, 3.00 m and 4.00 m working/transport width, and 4.00 m, 5.00 m and 6.00 m in a foldable mounted version, with a transport width of 2.50 m for these latter models.

The trailed models are available in 4.00 m, 5.00 m, 6.00 m and 7.00 m working width versions, also foldable, with a road width of 3.00 m.

VFM or VFM Mixing tines deliver excellent mulching
The distinctive feature of the STXV range is its original New Holland vibrating tine, which provides excellent mulching of the soil and residues. Two types of tines are available: the VFM tine, with 11 cm share, and the VFM Mixing tine, with a 8 cm share and 280 mm wings that scalp the soil surface across the entire working width of the implement.

The tines are mounted on 4 rows, spaced 600 mm apart, with a pitch of 235 mm. This tine layout on the frame, combined with the high under-frame clearance (800 mm), allows an optimal flow of soil without clogging.

In the event of an obstacle, the tine retracts thanks to its leaf spring safety, then returns to its initial position. A levelling system then completes the work of the tines, using hockey-stick levellers or Ø460 mm levelling discs, arranged in pairs and fitted with spring safety.

Finally, the finishing work is carried out by a roller, which also controls the working depth. Three types of rollers are available:
- Vibro pack roller Ø570 mm, with spring blades, very versatile in all soil types
- Cage roller Ø550 mm, light and providing good crumbling
- Max pack roller, Ø550 mm, for increased soil re-consolidation, especially in heavy soils

On the trailed versions (except STXV 400T), two gauge wheels at the front of the implement ensure its stability. Note that on the trailed versions, several types of hitch are available depending on the user's needs: Cat. 3 hitch, Cat 4, Ø 40 or 50 mm ring, or K80 type hitch.

For the transport wheels, the standard tyre fitment is 380/55-17. For users wishing to limit soil compaction when turning at headlands, a 480/45-17 fitment is available as an option, which also increases the stability of the implement during transport.

A version with a row of discs at the front
The trailed STXV models are also offered with a row of discs at the front of the implement (optional).

This row of Ø460 mm notched discs is mounted on VFM-type springs, in front of the tine section, which act both as a safety system and adjust the pressure on the disc. These discs are particularly useful when working with large amounts of residue or straw, making it easier to cut the plant material and improving its breakdown in the soil.

The versatile STXV range, adaptable to a wide range of tractor power outputs.
The mounted models are designed for tractor power from 80-130 ch (3.00 m version) up to 200-250 ch (6.00 m version), depending on soil types. For the trailed versions, the recommended tractor power range runs from 130-170 ch (4.00 m version) to 240-300 ch (7.00 m trailed version).
