Pruning Method
Only manually
Mechanised pre-pruning + manual
Fully mechanised
Pruning OperationsSpecify the pruning operations that are carried out. Check as many as apply.
Manually shears
Assisted shears
Chainsaw/ armchainsaw
pre-pruner:hedge trimmer
pre-pruner:discs
pre-pruning topping
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.
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)Serrat Olipack T1800
Round bale
Baler (manufacturer-model)
Squared bale
Baler (manufacturer-model)
