Agricultural mouldboard plough manufacture

1. Scope and Applicability

This PCR covers manufacture of new complete tractor-mounted and semi-mounted mouldboard ploughs that cut and invert soil with a share and mouldboard, including reversible and slatted-body configurations. It defines a foreground manufacturing data package from identified incoming stock or purchased components to factory acceptance and dispatch packaging. Farm use, hectare-based ploughing service, tractor manufacture, soil carbon, crop yield, replacement parts sold alone, disc ploughs, rotary tillers, harrows, subsoilers and remanufacturing are excluded. A kilogram of differently configured ploughs is not evidence of equal field performance.

4. Measurement and Unit Rules

rule_id	Applies to	Required property	Required unit	Rule
reference_mass	reference product	Mass 93a60a56-a3c8-11da-a746-0800200b9a66	kg	M = accepted net mass of one complete machine of the same configuration in kg; collect using cp_mass.
energy_basis	electricity	Net calorific value 93a60a56-a3c8-11da-a746-0800200c9a66	MJ	Retain the electrical meter basis; use the energy unit-group factor 1 kWh = 3.6 MJ. Do not interpret electricity as fuel calorific input. Selected 35–330 kV flow needs a matching supply boundary.
gas_volume	thermal_gas	Volume 93a60a56-a3c8-22da-a746-0800200c9a66	m3	Record actual or standard conditions with meter correction evidence; volume-to-mass conversion requires gas composition and measured density at the declared conditions.

5. System Boundary

Boundary Abstraction

Field	Value
declared_starting_condition	Identified received steel stock or finished supplier components, at declared receiving gate; all external inputs and inbound transport coverage disclosed
starting_condition_role	foreground manufacturing start
product_classification_scope	CPC 3.0 44111 mouldboard subset
recursive_input_rule	A purchased complete plough entering modification remains a separately recorded same-category input with its supplier dataset; stop recursion at that identified input and disclose the changed configuration
upstream_dataset_requirement	Link steel, each purchased component and utility to compatible upstream datasets; without complete verified upstream linkage describe foreground manufacture only
disclosure	Site/time; starting states; outsourced treatment; route exceptions; missing suppliers; transport; capital-equipment coverage; waste-treatment destination

rule_id	applies_to	rule	source_ids
boundary_manufacture	all processes	Include actual manufacturing, internal handling, rework, attributable utilities, acceptance testing and dispatch packaging within the declared site/process chain. Record outsourced heat treatment as supplier activity instead of also counting its fuel locally. This is a foreground protocol, not proof of complete cradle-to-gate coverage.
boundary_route	thermal; joining	Select operations from drawings and route cards. Manufacturer examples support forging and heat treatment for some shares; DuraMaxx wear bodies illustrate absence of drilling/punching/welding. Neither is universal. Add each actual carburising medium, quench oil, cleaner, abrasive, structural tube, wheel, hose and safety component as an individually identified exchange before claiming configuration completeness.	lemken-plough-bodies; kverneland-share-production; kverneland-steel-technology
boundary_environment	all processes	Elementary flows cross to the environment only. Supplied process water is a product input; externally treated rinse effluent is a waste output. Quantify route-specific air/water releases only from measurements or documented constituent balances; unknown species must not be invented or merged into NOx/VOC placeholders.

6. Process Inventory Structure

Process Map

process_id	process_name	inclusion	inclusion_condition	role	quantitative_reference
forming	Stock preparation, cutting and forming	conditional	When frame or body blanks are fabricated inside the declared foreground	foreground production	per 1 kg reference flow
thermal	Wear-part forging and thermal treatment	conditional	When forging, hardening, tempering or carburising is performed inside the declared foreground	foreground production	per 1 kg reference flow
joining	Joining of structural parts	conditional	When welded joints are present in the foreground route	foreground production	per 1 kg reference flow
finishing	Cleaning and protective finishing	conditional	When performed inside the foreground; powder coating is one conditional route, not a universal requirement	foreground production	per 1 kg reference flow
assembly	Configured assembly and acceptance	required	All complete implements	foreground production	per 1 kg reference flow
packing	Factory dispatch packaging	conditional	When dispatch protection crosses the foreground boundary	foreground production	per 1 kg reference flow

These rows are conditional atomic exchanges, not a universal recipe. Extend them from the exact BOM/route and meter register; report demonstrable absence as not applicable, and unknown amounts as gaps. Internal part transfers conserve configuration and mass but are not external purchases. No ranges are assigned from manufacturer marketing claims.

7. Allocation and Co-product Handling

rule_id	applies_to	rule	source_ids
allocation_direct	all processes	Use direct job/lot records and subdivision first. For shared equipment measure job machine-hours and measured load, reconcile assigned plus unassigned consumption to the meter, and retain the physical causal basis. Mass allocation is allowed only when a site test establishes proportional processing demand; unequal plough configurations cannot automatically be allocated by unit count or finished mass.
allocation_scrap	waste outputs	Record steel chips, offcuts and coating residue with destination and revenue status. Sale alone does not establish a co-product or authorize an avoided-steel credit. Keep waste-treatment and recycling burdens/benefits explicit in the chosen study method; disclose any economic allocation, price period and sensitivity when physical allocation is unsupported.
allocation_rework	forming; assembly	Attribute rejects and rework to their originating configuration and count accepted output once. Recoverable internal steel/powder circulations are tracked separately from net purchased inputs and external wastes.

Calculation Rules

rule_id	Applies to	Formula or rule	Inputs	Output	source_ids
normalize_mass	all inventory rows	q_ref = q_item / M; q_item = exchange amount per one accepted finished machine; q_ref = exchange amount per 1 kg reference flow.	q_item; M; cp_mass	q_ref

Batch production: determine attributable exchange and the accepted complete output from the same configuration and period before computing the per-machine record. A pooled dataset with variable masses uses total attributable exchange divided by total accepted net mass; preserve the machine records and do not average per-machine ratios without weights. External emissions factors require a named source and site applicability evidence, and are not supplied by this PCR.

Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence
quality_configuration	reference product	Keep body count, material, support, reset/hydraulic options and acceptance consistent with M; distinguish gross shipping mass and incomplete kit mass.	BOM and calibrated weighing
quality_route	all processes	Specify foreground vs purchased parts; record heat treatment recipe and coating chemistry where used. A manufacturer example is route evidence, not a universal recipe, yield or lifetime.	lemken-plough-bodies; kverneland-share-production; kverneland-steel-technology
quality_completeness	all inventory rows	Reconcile BOM and material balances, utility meters, inventory changes, rejects, packaging and waste destinations. Quantify omitted exchanges and justify each exclusion; gaps are not zero.	job ledger and reconciliation
quality_range	all inventory rows	No transferable quantity ranges are established. Collect site-specific records and uncertainty; do not use advertised wear-life gains, carburising time or catalogue mass as factory inventory factors.	measurement records and explicit evidence gaps

9. Validation Rules

rule_id	applies_to	rule	source_ids
validate_basis	all inventory rows	Require positive measured M, same accepted configuration, reference output exactly 1 kg, explicit normalize_mass application and compatible numerator units. Record gas conditions and electricity conversion evidence.
validate_identity	all inventory rows	Verify each UUID public identity, reference property/unit, route, origin and environment compartment before dataset use. An unresolved flow remains a named exchange without UUID and blocks a claim of complete identity coverage; no forced substitute.
validate_complete	reference product	Check exact BOM coverage including wheels/rims, bolts/nuts, hoses, seals and overload mechanisms when fitted; add each missing atomic exchange and supplier activity. Check route omissions and direct emission species. Report performed, skipped, uncertainty and remaining gaps; manufacturing checks do not validate farm performance.

10. Published Dataset Profile

Field	Value
dataset_role	Configured foreground manufacture of a complete mouldboard plough
downstream_use	secondary_dataset; background_dataset
allowed_use	Supply compatible configured plough manufacture to a separately modelled equipment life cycle; upstream use only after linkage and coverage review
excluded_use	Crop yield, soil carbon, comparative hectares, universal lifetime, disc-plough manufacture, claims of complete cradle-to-gate without upstream verification
required_metadata	Configuration qualifiers; M protocol; site/period; route; receiving state; supplier activities; boundary diagram; property/units; allocation; packaging; waste destinations
required_quality_disclosure	Identity gaps; missing BOM/suppliers; measurement uncertainty; skipped processes; unverified emissions; range evidence gaps; upstream and transport completeness
update_trigger	Configuration, steel grade, treatment route, coating, supplier, utility mix, measured mass or boundary changes
