Mechanized Collection
Preparation of the field prior to harvesting

No preparation - prunings were left on the soil as they fall from tree

Centre-operatos position prunings on the center of the lane between tree rows

Centre alligned-operators position prunings in a specific position in center
(e.g. alligned with the direction of the row)

Previous windrowing-a tractor with windrower is used prior pruning harvester

Integrated windrower to the pruning machine


Type of pruning treatment and model of machinerySpecify the method that prunings are treated based on the outcome product and manufacturer-model of each machinery (windrower,mulcher,chipper,baler) that is used if applicable

Windrower-Machines that allign biomass in a row



Windrower (manufacturer-model)


Mulcher-big pieces. Machines that break the branches in big pieces.
Normally they are an evolution from the typical muchers/cruchers utilised to leave
the branches on the soil in pieces.

Mulcher (manufacturer-model)


Shredder - Produce finer material (hammers or hammers with a knive.Do not produce a clear cut)



Shredder (manufacturer-model)


Chipper - Clean cut. Resembles the typical form of forest woodchips



Chipper (manufacturer-model) Jordan tractor mounted disc chipper


Round bale

Baler (manufacturer-model)


Squared bale

Baler (manufacturer-model)

Harvesting losses,  were not measured because it appeared to be very limited.
