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) SERRAT "Biomass 100"


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



Chipper (manufacturer-model)


Round bale

Baler (manufacturer-model)


Squared bale

Baler (manufacturer-model)

Problems encountered due to the field

Soil uneven
Slope


Stones
Too much grass


The grafting pruning had been first object of topping; then partially mulched; after new cutting of


Problems encountered by the machines

Not suitable for the pruning
Manouvering


Unsuitable feeding system (biomass difficult to be conveyed)
Too much soil particles with the biomass to be treated


Problems in discharge


It was not able to turn at field end. So, after a row it had to drive back to the gead of the line.


Performance of the machinery

The machinery was performing better than expected

The machinery was performing normally-typical expected

The machinery was underperforming
