GRATOR
PREPARADOR DE PRECISÃO DA CAMA DE SEMENTEIRA
CHASSIS DESDOBRÁVEL
GRATOR is a vibrotiller for seedbed cultivation: in just one pass front bar levels soil, many elastic tines (10 per meter) refine it; the double cage roller levels ridges and furrows left from tillage. Frame is light but extremely strong, up to 6 m mounted and up to 12 m pull type versions are available.

Frame
Hydraulic folding frame to optimize transportation of wider versions (450 to 1200).
Tines working
Seedbed preparation is performed by 4 ranks of elastic tines: 10 tines per meter are the guarantee for total tillage of the soil front. Spacing of 400 mm between tines of the same rank avoids residues congestion even at maximum working depth. According to surface conditions efficacy of residues burying varies from 40 to 70%.
How to choose tine type
Two kinds of elastic tines are available.
Gamma tine: the shape of this tool refines soil but doesn’t invert tilled layer: this preserves seedbed moisture, keeping optimal conditions for seed emergence even in water shortage.
Delta tine: this solution produces a minimal but effective soil turning, favorable to control weeds emerged after primary tillage or to spread crop residues in tilled layer.
Leveling bar
A front bar levels and prepares soil for the action of elastic tines: height of this element can be quickly adjusted by pins.
Rollers
Two rear cage rollers complete optimal seedbed preparation and leveling. They have also the function of matching ideal working depth of tines, with a simple pin and tie-rod system.
Rear trolley
Heavier versions (900 and 1200) have a rear cart to make easier machinery transportation. During soil tillage wheels can be lifted by an hydraulic circuit to avoid compaction of tilled soil.
2 point hitch
Our cast two point hitch allows for easy hookup and great versatility in the field because of the multiple pivot points; its available for wider versions of the machinery (900 and 1200).
Safety hydraulic lock
Folding frame versions have an hydraulic lock to improve safety during road transportation. Its totally automatic and driver doesn’t need to leave tractor cab to activate it.
