Crop Species




Age of crop

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

Harvesting methodsCheck according to the figures below the harvesting method that is used for the pruning biomass

Manual cross-cutting of firewood+gathering at field side

Forestry chipper towed by tractor + manual feeding

Hauling the branches + shredding/chipping at field side

Hauling the branches + baling at field side

Harvest with mulcher/chipper in front

Harvest with mulcher/chipper at rear

Harvest with rear mulcher/chipper and bin

Harvest with rear mulcher/chipper and big-bags

Automotive shredder/chipper with rear trailer

Harvest with standard hay baler

Harvest with rear baler prepare for wood or tree branches

Pre-pruning integrated with collection and mulching/chipping

Pre-pruning integrated with collection and mulching/chipping in an automotive 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.

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

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

Information found in the following paper:

Assirelli A., Acampora A., Croce S., Spinelli R., Santangelo E., Pari L., Mechanized recovery of olive pruning residues: ash contamination and harvesting losses. Journal of Agricultural Engineering 2013; volume XLIV(s2):e124. doi:10.4081/jae.2013.s2.e123

The paper investigates six harvesting machines (shredders): 1) Tierre Futura 160; 2) Omat TSB 1900; 3) Nobili TRP-CV 145; 4) Sgarbi TR-RAC; 5) Facma Comby TR 200; 6) Berti Piker-Kargo 200.

Particle size distribution for three classes (< 5 mm, 5 - 10 mm, > 10 mm) is given for each of the six tested harvesting machines.

The ash content of the collected biomass and the harvesting losses were evaluated for each harvesting machine under three different pick-up settings:  standard  height  set  by  the  manufacturer (setting  B); working height 1 cm above ground level (setting A); working height 3 cm above ground level (setting C).

No information on fuel consumption and working times is provided by the paper.
