Vibra bed-former

The Vibra bed-former is a secondary cultivation tool and a bed former. It’s based on a spring tine cultivator, but also has an adjustable comb weeder and a hydraulically assisted drum roller.

It was developed as an alternative to PTO driven bed formers. Its working speed is 2 to 3 kms per hour. It’s a very useful tool for weed control on beds that have not yet been sown or transplanted. For destroying weeds, the tool should work just below the surface of the soil, with a driving speed of 5 to 6 kms per hour. The Vibra bed-former can also be used to destroy young green manures, if it is followed by a pass with the Bed Ridger to ensure the green manure is incorporated back into the ground. The joints and articulations make driving and adjusting the tool simple.

The tool cannot incorporate crop residue in the same way as PTO driven cultivators. The spring tines drag organic materials and the tool can be clogged up.

Possible adaptations
It’s possible to replace the drum roller with a cage roller, which levels out the soil without compacting it.
The traditional spring tine blades can also be replaced by straight tines which bring up less soil and weed seeds to the surface. It would also be useful to have the option of adjusting the depth of the side spring tines working in the wheelings.
