Shopify Outdoor Power Equipment Schema — Engine CC, Battery Platform, Cut Width, OPE Structured Data

Q: How do I encode engine displacement for outdoor power equipment in schema.org?

Use 'additionalProperty' with PropertyValue, unitCode 'CMQ' (cubic centimeters): { '@type': 'PropertyValue', 'name': 'Engine Displacement', 'value': '190', 'unitCode': 'CMQ', 'description': '190cc OHV (overhead valve) 4-stroke engine. Displacement is the primary power signal for gas-powered OPE — directly correlates with torque output and ability to handle thick grass, steep grades, or heavy loads. 163cc handles flat yards up to 1/4 acre; 190cc for grades up to 20% and thicker grass; 223cc+ for rough terrain and heavy-duty applications.' }. For 2-stroke engines (chainsaws, most string trimmers), also note the fuel mix ratio: { '@type': 'PropertyValue', 'name': 'Fuel Mix Ratio', 'value': '50:1 (gasoline to 2-stroke oil)', 'description': '50:1 ratio (100ml oil per 5L gasoline). Using incorrect mix ratio causes engine failure — too little oil causes seizure; too much causes fouled plugs and smoking.' }.

Q: How do I encode OPE battery platform compatibility in schema.org?

Battery platform compatibility is the single most important purchase filter for cordless OPE — a buyer already invested in EGO 56V batteries will not buy a Greenworks 80V tool. Use 'isCompatibleWith' with explicit voltage and platform name, plus an 'additionalProperty' noting physical incompatibility: { '@type': 'PropertyValue', 'name': 'Battery Platform', 'value': 'EGO POWER+ 56V ARC Lithium', 'description': 'Compatible with all EGO POWER+ 56V ARC Lithium batteries (BA1400T / BA2800T / BA6000T and all 56V EGO batteries). EGO 56V batteries are NOT compatible with other brands — platform is physically and electrically incompatible with DeWalt, Greenworks, Ryobi, and other OPE battery systems. Battery sold separately.' } and { '@type': 'PropertyValue', 'name': 'Battery Voltage', 'value': '56', 'unitCode': 'VLT', 'description': 'EGO POWER+ 56V nominal voltage platform. Peak voltage: 60V. Higher voltage platforms (72V, 80V, 82V) have more power-dense motors but require different batteries.' }. The locking nature of OPE battery platforms — EGO 56V, Greenworks 60V, Greenworks 80V, DEWALT FLEXVOLT 60V/120V, RYOBI 40V, RYOBI 80V, Makita 40V XGT, Husqvarna XPLORER 36V — means that battery platform is a stronger purchase filter than product type.

Q: How do I encode mowing deck cut width in schema.org?

Use 'additionalProperty' with name 'Cut Width' and unitCode 'INH': { '@type': 'PropertyValue', 'name': 'Cut Width', 'value': '21', 'unitCode': 'INH', 'description': '21-inch cut width. Standard residential push mower cutting width. Passes needed for yard sizes: 1/4 acre = ~45 passes, 1/2 acre = ~90 passes. Wider decks (22–30 inch) reduce passes for larger yards. Note: 21-inch deck does not mean 21-inch blade — deck width includes blade rotation arc and housing.' }. Also encode cut height adjustment range: { '@type': 'PropertyValue', 'name': 'Cut Height Range', 'value': '1.5 to 4 inches', 'description': 'Six position single-lever height adjustment. 1.5 inch minimum (scalping risk — not recommended), 2.5–3.5 inch optimal for most grass types in summer heat. Each grass type has a recommended mow height for health.' }. For riding mowers and zero-turns, encode deck width separately from blade span and add turning radius ZeroTurnRadius for zero-turn models.

Q: How do I encode chainsaw bar length in schema.org?

Use 'additionalProperty' with name 'Guide Bar Length' and unitCode 'INH': { '@type': 'PropertyValue', 'name': 'Guide Bar Length', 'value': '16', 'unitCode': 'INH', 'description': '16-inch guide bar. Effective cutting capacity: up to 15-inch diameter logs in a single pass. For limbing: 8-14 inch bar. For felling trees: bar length should exceed trunk diameter by 2+ inches — 18-inch bar for 16-inch trunk. Bar and chain are paired — replacement chain must match bar gauge (pitch and drive link count).' }. Also encode chain pitch and gauge: { '@type': 'PropertyValue', 'name': 'Chain Pitch', 'value': '3/8 inch LP (Low-Profile)', 'description': 'Oregon 91 (3/8 inch low-profile pitch). Low-profile chains are standard on consumer chainsaws under 2.0 cubic inch displacement. Pro/full-pitch chains (3/8 inch standard or .404 inch) are for higher-displacement saws and are NOT interchangeable with low-profile — gauge and drive link count must match.' } and { '@type': 'PropertyValue', 'name': 'Chain Gauge', 'value': '.050 inch', 'description': 'Drive link gauge .050 inch (1.3mm). Groove width of the guide bar must match chain gauge exactly. Mixing gauge causes chain derailment and safety hazard.' }. Chain pitch, gauge, and drive link count are the three parameters needed to order a replacement chain — all three should be in the structured data.

Q: How do I encode EPA engine certification for gas-powered OPE?

Use 'hasCertification' with the relevant EPA tier: { '@type': 'Certification', 'name': 'EPA Phase 3 Compliant', 'issuedBy': { '@type': 'Organization', 'name': 'U.S. Environmental Protection Agency', 'url': 'https://www.epa.gov' }, 'description': 'EPA Phase 3 handheld engine standard — applies to chainsaws, leaf blowers, string trimmers, and other handheld gas OPE. Reduces hydrocarbon + NOx emissions versus Phase 1 and Phase 2. Required for sale in all 50 US states from 2012 onward.' }. For California: add separate CARB Tier 3 hasCertification — California Air Resources Board has more stringent emission requirements than federal EPA. CARB Tier 3 non-handheld covers walk-behind mowers, generators. CARB Small Off-Road Engine (SORE) Tier 3 covers handheld. Products not CARB-certified cannot be sold legally in California, Oregon, and several other states that adopt CA emission standards. For electric (corded or battery): EPA certification does not apply to motors — use Energy Star or battery UL certification instead.

AI shopping agents handling queries like "EGO 56V 21-inch self-propelled mower," "56cc chainsaw with 18-inch bar CARB certified," "battery leaf blower 800 CFM compatible with Greenworks 80V," or "zero-turn riding mower 52-inch deck under $4,000" need machine-readable engine displacement, battery platform compatibility, cutting width, bar length, CFM/MPH air output, and certification data. Shopify's default JSON-LD for a gas lawn mower returns nothing but name and price — every CC rating, cut width, and EPA compliance signal that separates a homeowner mower from a commercial-grade machine is invisible to the AI agents now ranking and recommending OPE.

TL;DR Use Product @type with additionalProperty for powerSource (Gas/Battery/Corded Electric), engineDisplacementCC (unitCode CMQ), battery platform (brand + voltage + VLT unitCode), cutWidth INH (mowers), guidBarLength INH (chainsaws), airOutputCFM (blowers), airSpeedMPH (blowers), noiseLevel dB (unitCode 2N), weightKG (unitCode KGM), and selfPropelled boolean. Add hasCertification for EPA Phase 3 / CARB compliance, UL certification, and noise compliance. Use isCompatibleWith for battery cross-tool compatibility. Store values in an ope.* metafield namespace.

Why OPE Products Are Structurally Invisible to AI Agents

Outdoor power equipment purchases split into two fundamentally different buying contexts. Gas-powered OPE buyers filter first on engine displacement (cc) as a proxy for power, then on specific task dimensions (cut width for mowers, bar length for chainsaws, CFM/MPH for blowers). Battery-powered OPE buyers filter first on battery platform compatibility — a buyer already committed to EGO 56V will not buy a Greenworks 80V tool regardless of its specs, because the battery investment is non-transferable between platforms.

Neither filter is addressable with Shopify's default schema output, which returns only name, price, and availability. The result is that AI agents comparing "EGO LM2102SP vs Greenworks Pro 25302" cannot determine battery incompatibility from structured data, and a query for "190cc self-propelled mower under $400" cannot be answered because neither product has cc displacement in its schema.

The OPE category has an additional problem: power claims between gas and battery OPE are inherently incomparable. A "40V battery chainsaw" and a "40cc gas chainsaw" are entirely different power levels — voltage does not convert to cubic centimeters. AI agents need both figures (for respective product types) without confusing the metrics. Battery tools should encode watt-hours (WH) for capacity, not voltage alone.

OPE Battery Platform Landscape

Brand	Platform	Nominal Voltage	Peak Voltage	Compatible tools
EGO	POWER+ ARC Lithium	56V	60V	Mowers, chainsaws, blowers, trimmers, tillers, snowblowers, pressure washers
Greenworks	Pro 60V	60V	60V	Mowers, chainsaws, blowers, trimmers — NOT compatible with Greenworks 40V or 80V
Greenworks	Commercial 82V	82V	82V	Commercial OPE — separate from consumer 60V platform
DEWALT	FLEXVOLT 60V MAX	60V MAX	60V	Backwards-compatible with 20V MAX tools (runs at 20V in 20V tools)
RYOBI	ONE+ HP 40V	40V	40V	Lawn OPE — NOT compatible with RYOBI ONE+ 18V or RYOBI 80V
Husqvarna	XPLORER 36V	36V	36V	Robotics and handheld — separate platform from Husqvarna battery mowers
Makita	40V XGT	40V max	40V	Pro/commercial OPE — separate from Makita 18V LXT and 36V (dual 18V)
Milwaukee	MX FUEL	72V (2×36V)	72V	Commercial OPE (cordless concrete saws, vibratory plates) — not compatible with M18/M12

Platform incompatibility is physical — connectors and voltages are not interchangeable. Publishing battery platform as a structured additionalProperty (with brand name, nominal voltage, and compatibility notes) is the single highest-value structured data addition for battery OPE because it directly resolves the buyer's first filter: "does this tool work with batteries I already own?"

5 Critical OPE Schema Mistakes

Publishing voltage without platform name for battery OPE. "40V" describes products from RYOBI, Greenworks, Makita (XGT), Worx, and others — all physically incompatible with each other. Platform name (EGO POWER+, Greenworks 60V, DEWALT FLEXVOLT) is the actual compatibility filter.
Omitting fuel mix ratio for 2-stroke gas OPE. Incorrect fuel mix is the leading cause of small engine damage. 2-stroke chainsaws, trimmers, and blowers require 40:1 or 50:1 ratios — this must be in structured data for AI agents advising buyers on maintenance.
Publishing only chain bar length without pitch, gauge, and drive link count. Replacement chain requires all three values simultaneously. Bar length alone is insufficient for chain ordering.
Confusing sound power level and sound pressure level. Sound power level (dB LW, per Directive 2000/14/EC) and sound pressure level (dB LP at operator ear) differ by 10–15 dB. Always specify which measurement is published — they are not interchangeable in schema.
Missing CARB compliance status for California-eligible products. CARB compliance determines legal sale eligibility in California and ~15 other states. Gas OPE without CARB compliance cannot be sold in those states — a binary purchase filter AI agents must resolve from structured data.

Frequently Asked Questions

How do I encode engine displacement for outdoor power equipment in schema.org?

Use additionalProperty with unitCode CMQ (cubic centimeters). For 2-stroke engines also add fuel mix ratio as a separate PropertyValue. Displacement tiers: under 35cc = light limbing/trimming; 35–45cc = felling up to 12-inch trees; 46–60cc = felling up to 18-inch trees; 60cc+ = professional felling.

How do I encode OPE battery platform compatibility in schema.org?

Use additionalProperty with the full platform name (brand + voltage + platform name), plus a second PropertyValue for nominal voltage with unitCode VLT. Note that all major OPE battery platforms are physically incompatible with each other. Battery platform is the primary purchase filter for cordless OPE buyers with existing battery investments.

How do I encode mowing deck cut width in schema.org?

Use additionalProperty with name 'Cut Width' and unitCode INH. Add a separate entry for cut height range (e.g., '1.5–4 inches' with position count). For riding mowers also encode deck width vs blade span and turning radius.

How do I encode chainsaw bar length in schema.org?

Use additionalProperty with name 'Guide Bar Length' and unitCode INH. Also encode chain pitch (3/8 LP vs 3/8 standard vs .404), chain gauge (.043/.050/.058/.063 inch), and drive link count for the included bar length. All three are required for replacement chain ordering.

How do I encode EPA engine certification for gas-powered OPE?

Use hasCertification for EPA Phase 3 (handheld: chainsaws, blowers, trimmers) or EPA Small Spark-Ignition non-handheld (walk-behind mowers). For California sales, add separate CARB SORE Tier 3 certification — required in CA, OR, WA, and ~15 other states. Battery OPE has no engine emissions certification requirement.
