Most first-time dealers work out machine margin to two decimal places and then treat spare parts as an afterthought. Twelve months later the pattern is familiar: the best technicians spend their time chasing couriers instead of billing hours, machines sit idle for three weeks in peak season, and the customers who were excited at handover are quietly telling peers that support was slow.
Parts and service are where distribution businesses actually make their money and keep their customers. This guide covers what to hold, what it costs, how to set up a warranty process that does not eat your team, and how to turn the mowing season into recurring revenue. The advice applies whichever line you carry — including ours, and including your competitors'.
Why parts economics decide whether you stay in the business
Three numbers explain most of it.
- Machine sales are cyclical and infrequent. A good account buys one machine every two or three years.
- Parts and consumables recur every season, at margins that are frequently higher than the machine.
- Downtime is visible. Contractors judge their supplier by how fast the machine is running again, not by purchase price. The account you win next year is won during this year's breakdown.
Dealers who rely on unit margin alone are the ones discounting hardest. Dealers who carry parts and run preventive maintenance are the ones quoting without flinching, because the relationship income is predictable.
Know the four consumption groups
Organising stock by how fast things move is more useful than organising by what the component is.
| Group | Typical items | Consumption pattern |
|---|---|---|
| Cutting consumables | Flails or hammers, pins, blade bolts, deck belts, rotor bearings, belt guards | Per job site. Abrasive or scrubby ground can double or triple usage — highest turnover line you carry |
| Drive and chassis wear | Rubber tracks, drive sprockets, idler wheels, tension blocks, track guides | Season-scale. Heavily influenced by operator habits and terrain; the largest single revenue item after the machine itself |
| Powertrain service | Air and oil filters, spark plugs, fuel filters, engine oil, drive belts, seals and gaskets | Scheduled. Predictable once you know service intervals — the backbone of your annual maintenance contract |
| Electronics and controls | Transmitter units, receivers, aerials, wiring looms, switches, emergency stop components, batteries and chargers | Low volume, high pain. A failed transmitter stops everything, so never stock zero |
A useful rule: anything in the first two groups has to be available within 24 hours for every machine you have sold. Anything in the fourth should be on your shelf in at least one unit, even if it moves twice a year.
Starter stocking packages
Figures below are indicative of what a dealer typically opens with, expressed as a proportion of machine value. Adjust for your market's freight reality and how remote your customers are.
| Year-one machine volume | Recommended opening stock | Focus |
|---|---|---|
| 1–5 machines | Approximately 3–5% of the machine value on the shelf | Cutting consumables, full service kit per model, one spare transmitter, one emergent set of drive wear parts |
| 6–15 machines | Approximately 5–7% | Add a full per-model wear package (tracks, sprockets, belts) and duplicate high-failure electronics |
| 15–30 machines | Approximately 7–10% | Add second machine's worth of cutting stock, one complete rotor assembly, and a loaner transmitter pool |
| Multi-branch territory | Per branch plus a central buffer | Keep slow, expensive items central; consumables at every branch |
Notice that none of these numbers is huge. Tying up roughly a twentieth of your machine spend in inventory is what separates a dealer who answers the phone with a delivery date from one who answers with an apology.
Get the parts book before the first vessel sails
Two documents are non-negotiable a full shipping cycle before your first delivery lands:
- An exploded parts diagram per model, with numbers you can quote in an email. If you have to describe a part with adjectives on a phone call, you will order the wrong one.
- A cross-referenced service schedule showing intervals in engine hours, so you can build quoted maintenance packages. If 100-hour service intervals are unclear, every service quote becomes a negotiation.
Ask both early, in writing, along with the parts availability commitment for discontinued models. Anything reasonable, and any manufacturer serious about supporting a territory, will produce them quickly.
A warranty process that does not consume your technicians
Warranty claims mostly go wrong through slow diagnosis, not through rejection. A workable sequence:
Step 1: capture evidence at the failure point
Ask the operator for: machine serial and engine serial, engine hours, photos of the failure and the surrounding area, and one short video of the symptom if it is still reproducible. Most premature wear claims are resolved — or dismissed — from those four items alone.
Step 2: classify before you touch
Three buckets: manufacturing defect, wear beyond expected life, and application or operational damage. Only the third usually sits outside warranty, and being clear about which is which early protects the customer relationship.
Step 3: ship to return only what must come back
Agree in advance which failed parts your supplier needs physically and which can be closed with photographs. Every unnecessary cross-border freight costs you weeks and goodwill.
Step 4: close the loop in writing
Even a declined claim should end with a document explaining why and what to do differently. Operators accept a well-explained no far more readily than silence.
Seasonal calendar for European dealers
Parts demand follows the grass, and it starts earlier than most new dealers expect.
- January–February: place orders. Anything on a container is realistically not on your shelf until spring. This is when you also run your demonstration campaign — see the notes on building a demo programme.
- March–April: pre-season servicing surge. Filters, belts, oil, and every deferred repair from last autumn arrives at once. Staff accordingly.
- May–August: peak consumable burn. Highest cutting parts turnover of the year; expect to reorder tracks and flails mid-season.
- September–October: the second wave — roadside clean-up and pre-winter reclamation work, often the toughest conditions of the year.
- November–December: stocking clean-up and annual physical count. Best time to audit min/max levels against what actually moved.
Turning service into recurring revenue
The most stable distributors we know stopped selling one-off repairs years ago. Three offers do most of the work:
Annual maintenance contract
Two visits per season, all scheduled service items included, labour billed at a fixed price. The customer gets predictable cost; you get predictable workshop load and first refusal on every part the visit uncovers.
Consumables plan
A seasonal box delivered before spring: adequate cutting consumables for the expected workload, service filters, and one set of everything they will certainly need. Charged upfront or in three instalments. Happy customers are the ones who never run short in June.
Priority response tier
Guaranteed response window during peak season for contract customers, priced as a subscription. This is margin funded by preparation, not by parts — and it is the single strongest retention tool most dealers under-use.
Uptime agreements change the conversation from price to availability, which is exactly where an established dealer beats a box-shifting importer.
Seven mistakes new dealers make
- Ordering stock after the first breakdown. Freight timing means the fix arrives three weeks after the customer stopped caring.
- Stocking only what they know sells, not what fails. The two lists differ. Ask for failure-rate data, order ceiling quantities accordingly.
- No serial-linked service history. Without it, you cannot spot patterns or defend a warranty position.
- Treating the manual as the customer's problem. Every installation should include a walkthrough and a handover checklist; see our operating safety rules.
- Ignoring whether their own regional regulations differ from what the machine ships with; the regional compliance notes are worth reading before the first import.
- Pricing service to win, not to sustain. Cheap first service, expensive follow-ups, and a customer who feels misled.
- No plan for end-of-life support. Know the parts availability window for discontinued models and tell customers at handover.
Frequently asked questions
How much working capital do I really need to tie up in stock?
For a typical start-up territory of up to ten machines in year one, plan for roughly 5% of machine value on the shelf, then review after the first full season against what actually moved. Holding far less almost always costs more in lost reputation.
Should I carry generic or genuine wear parts?
Genuine for anything that affects safety or control, and for items you will claim under warranty. Pattern parts for pure consumables can improve cash flow, but a pattern part failure during a customer's busiest week is a business-development setback, not a saving.
What is a reasonable response time for emergency support?
Have a documented policy per tier and publish it. Even "contact to diagnosis within one working day, parts dispatched within two" is far better than no policy at all — and it changes the tone of every hard conversation.
How do I handle a customer who fits their own modifications?
Document it at the moment you discover it. Unauthorised changes usually void warranty coverage for the affected assemblies, and putting that in writing protects both sides.
Do electric machines need less parts stock?
Less service stock — no filters, plugs or engine oil — but controller hardware, batteries and chargers are expensive enough that you still plan for them. Overall inventory falls; single-item value rises.
What we look for in a territory partner
When we appoint a distributor, factory capability matters less than local capability. Specifically: a workshop, a technician, stock on the shelf, and someone who picks up the phone in August. Everything else can be taught. We cover the commercial outline — margins, minimum order quantities and the support we provide — in the distributor programme overview, and the volume mechanics in the wholesale and reorder guide.
If you are building a parts operation and want the model-specific diagrams, service intervals and a stocking recommendation for your territory, talk to us before your first season starts, not during it.
