Agricultural parts

Built for the catalogs that move the harvest.

A Shopify compatibility app for ag parts — filters, bearings, hoses, gearbox components, hydraulic fittings. When equipment goes down during planting or harvest, shoppers don't have time to guess at fit. ModelMatch gives them the answer on the product page.

The downtime problem

Every minute of downtime costs real money.

Ag equipment doesn't go down at convenient times. It goes down mid-row, mid-field, mid-season — when the weather window is tight, the ground is right, and the operator needs the part today. A fit check on a product page is the difference between "back in the field by lunch" and "losing the weekend."

File 2026-A / 3 entries

ENTRY 01 Critical · peak season

Wrong hydraulic filter on a planting day

A farmer orders a transmission hydraulic filter for an 8R 250 based on a product page that lists "John Deere 8R series" — technically correct, but the 2019+ Tier 4 Final uses a different part than the 2015 Tier 4 Interim. The wrong filter arrives. The tractor stays in the shop. Forty acres of corn don't get planted that day.

Window missed: 24-48 planting hours
Opportunity cost: $200-$400 per acre delayed
Shop outcome: Customer buys next filter at local dealer, not online

ENTRY 02 Critical · peak season

Combine bearing fails mid-harvest

A Case IH 8250 operator needs a feeder house bearing at 4:40pm on a Friday. The Shopify product page lists "8240 / 8250 / 9240" — but the 8250 uses a different bearing depending on the feeder house variant and the year-range serial break. Without that granularity on the page, the operator calls the dealership instead of ordering online. That sale doesn't come back.

Window missed: Weekend harvest (daylight-critical)
Opportunity cost: Full weekend of cutting
Shop outcome: Lost sale · Ongoing parts business goes to dealer

ENTRY 03 Recurring · off-season

Off-season parts stocking gets hedged

A fleet manager preparing for spring pre-stocks filters, belts, hoses, and bearings across 30+ pieces of equipment. Without a finder that handles full-fleet compatibility lookups, the order splits across four dealer sites and the Shopify option — and yours usually isn't the one that gets the largest share, because it can't confidently answer what fits what.

Window missed: Pre-season stocking orders
Opportunity cost: Fleet-scale AOV, split across competitors
Shop outcome: Becomes secondary supplier, not primary

Operations plan

Three stages from upload to field-ready.

ModelMatch installs inside your Shopify admin, pulls in the compatibility data you already own, and deploys the shopper-facing surfaces that move parts during peak season. Every stage is documented, auditable, and reversible from the admin.

OPS · BULLETIN 010 Compatibility deployment plan · 3 stages

Season 2026

Stage 01

Pre-season

Map parts to equipment and operations

OB · 010-A

Import part-to-equipment, part-to-engine, and part-to-operation records via CSV, direct Shopify product import, or manual entry through the admin. ModelMatch supports the many-to-many compatibility structure ag catalogs actually have — one part mapping to 30+ equipment models across multiple engine families, year ranges, and serial number breaks.

Field outcome Compatibility database indexed and queryable

Stage 02

In-season

Shoppers confirm fit, even in the cab

OB · 010-B

The fit check loads fast on slow rural connections and works cleanly on phones in direct sunlight — because that's where the shopper actually is. Operators in the cab, dealer staff at the parts counter, fleet managers running the numbers the night before a planting day. Starter plans ship the product-page fit check and the catalog fit check; Growth and Professional unlock the standalone finder.

Field outcome Verified fit before checkout · fewer wrong-part orders

Stage 03

Post-season

Review, refine, expand coverage

OB · 010-C

Every fit check is logged. Match events carry forward as verified buyer intent. No-match events surface as a prioritized list of catalog gaps — so the next season's coverage expansion goes where shoppers actually searched, not where the merchant happened to think of. Review-cycle discipline builds compound coverage year over year.

Field outcome Compounding coverage · data-driven catalog growth

Parts reference

Three tools documented, ready for deployment.

Every ModelMatch install ships three shopper-facing surfaces. Each is catalogued, individually configurable from the admin, and designed to sit inside your existing Shopify theme without modification — so you can deploy what fits your operation and leave what doesn't.

Product-page fit check

Activates on every product page that has compatibility data. Accepts equipment model, engine model, year range, or serial number. Returns an immediate yes / likely / no answer with the matched cross-reference data visible — the same information a parts counter clerk would give a walk-in customer, surfaced on the web.

Surface: Every product page · auto-hides on unmapped records
Inputs: Equipment · Engine · Year · Serial
Response: < 200 ms typical · tested on rural 3G
Fitment: Yes · Likely · No · Unknown · reasoned

Standalone equipment finder

Dedicated finder page for equipment-first browsing. A farmer or fleet manager enters tractor, combine, planter, or baler details once and sees every compatible part across your catalog. Built for pre-season stocking orders and multi-part service jobs where the buyer is pulling ten SKUs, not one.

Surface: Dedicated finder page
Use case: Pre-season stocking · fleet orders
Cart: Native Shopify · multi-line

Catalog fit check

Drop-in theme app block for collection pages. Narrows a 400-SKU filter category, hydraulic hose category, or bearing category down to the parts that fit the shopper's specific equipment — without leaving the collection page. Perfect for high-volume categories where shoppers would otherwise leave to search elsewhere.

Surface: Any Shopify collection page
Config: Theme app extension · no code
Placement: Merchant-configurable · per-collection

Ag parts merchant questions

Answers for catalogs where downtime costs real money.

Does ModelMatch handle serial number breaks and production-year changes?

Yes. Map a part to a specific model with a year range or serial range, and the fit check resolves correctly based on what the customer enters. No manual logic required.

What about compatibility that depends on option packages or configurations?

Supported. Map the part to the specific configuration it fits — cab versus open station, standard versus MFWD, hydraulic versus mechanical. Customers who enter their full equipment details get the right answer.

Can I handle parts that fit equipment from multiple OEMs?

Yes. Aftermarket and universal parts are a core use case. Map one part to every compatible brand and model — John Deere, Case IH, New Holland, Kubota, whoever fits — and the fit check returns a match regardless of what the customer enters.

Does the fit check work on mobile and slow connections?

Yes. The widget is lightweight and loads asynchronously, so it works on rural connections and mobile devices in the field. Lookups typically respond in under 200ms even on slow networks.

We have decades of compatibility knowledge in our counter staff's heads. How do we capture that?

Start by importing the structured data you have — supplier cross-references, OEM catalogs, existing spreadsheets. Then add records as your counter team handles calls. ModelMatch grows with the data, and no-match events help you prioritize what to add next.

What does this cost?

ModelMatch starts at $19/month on the Starter plan, with Growth at $39/month and Professional at $79/month. Ag parts catalogs with deep SKU counts usually fit Growth or Professional.
