| 1 | Product Fit and Mower Configuration | Confirm whether the supplier produces battery-powered riding mowers suitable for residential, commercial, or municipal applications. | Technical datasheet showing cutting width, deck type, drive system, turning radius, slope rating, dimensions, and net weight. Compare like-for-like configurations. | 15% | — |
| 2 | Battery Chemistry and Electrical System | Check battery chemistry, nominal voltage, usable energy, battery-management system, protection functions, and replaceability. | Battery specifications in watt-hours, cycle-life test method, cell traceability, BMS protection data, and documentation aligned with IEC 62133-2 where applicable. | 14% | — |
| 3 | Runtime and Cutting Productivity | Evaluate mowing area per charge rather than relying only on a claimed operating time. | Ask for a controlled field-test report including grass height, grass moisture, cutting width, blade speed, terrain, operator load, temperature, and measured area per charge. | 14% | — |
| 4 | Charging System and Energy Efficiency | Review charger output, charging time, connector design, onboard charger protection, and energy consumption. | Charger input/output ratings, full-charge time measured from a defined state of charge, overcurrent protection, and watt-hours consumed per mowing test. | 8% | — |
| 5 | Safety and Regulatory Compliance | Verify blade-stop functions, seat or operator-presence controls, parking brake, reverse operation controls, emergency stop, and electrical protection. | Risk assessment, conformity documentation, test reports, user manual, safety labels, and applicable CE documentation. For EU sales, confirm the applicable machinery, EMC, and RoHS requirements. | 14% | — |
| 6 | Build Quality and Environmental Protection | Assess frame strength, deck corrosion resistance, wiring protection, connector sealing, vibration resistance, and water-exposure controls. | Material specifications, weld-quality records, corrosion-treatment details, ingress-protection test evidence where claimed, and validation testing under vibration and temperature conditions. | 10% | — |
| 7 | Manufacturing Capability and Quality Control | Confirm production ownership, assembly capacity, incoming inspection, end-of-line testing, and control of outsourced components. | Factory audit, ISO 9001 certificate validity, process flow chart, quality-control plan, defect-rate records, serial-number traceability, and sample inspection reports. | 10% | — |
| 8 | Customization and Documentation | Evaluate support for private-label configuration, regional electrical requirements, software settings, packaging, and manuals. | Approved drawings, bill of materials, multilingual manual, spare-parts list, packaging specifications, change-control process, and engineering-change records. | 6% | — |
| 9 | After-Sales Service and Spare Parts | Check warranty coverage, technical response time, spare-parts availability, diagnostic support, and repair procedures. | Written warranty terms, parts price list, recommended spare-parts stock, service-level agreement, troubleshooting guide, and confirmed support contact. | 5% | — |
| 10 | Total Cost, Logistics, and Commercial Reliability | Compare total landed cost, minimum order quantity, lead time, payment terms, packaging protection, and delivery consistency. | Formal quotation, Incoterms, production lead time, capacity-confirmation record, export packaging test, shipment history, and landed-cost calculation. | 4% | — |
