When Your Best Parts Manager Retires, What Goes With Them?

There's a version of this story playing out at dealerships across the country right now. A parts manager with 25 years under their belt announces they're retiring. Everyone claps, has some cake, then Monday morning comes and the person behind the counter realizes they have no idea why certain parts are stocked the way they are.

The Knowledge That Doesn't Live Anywhere

Ask a seasoned parts manager why they keep 14 units of a particular hydraulic seal on hand and they'll tell you exactly: one customer runs four machines hard in a sandy environment, two others are coming up on scheduled maintenance, and that seal tends to fail about 800 hours in. They didn't learn that from a report. They learned it by paying attention for years.

That kind of know-how — the stuff that lives in someone's head — is what actually drives stocking accuracy at most dealerships. Experienced people know which customers call before a breakdown, which brands run hot in summer, which parts always seem to go together. They've built informal systems on top of the formal ones because the formal ones don't account for any of it.

When that person retires, none of that knowledge transfers automatically. It doesn't live in the DMS. It doesn't get captured in a handoff document. It walks out the door with them.

"The part wasn't in the system as low stock. It just wasn't something we ordered anymore — because Jim knew we didn't need it until spring."

A Problem That's Getting Harder to Ignore

In a 2024 DIS survey of ag equipment dealers across North America, 87% cited hiring and retaining talent as their single biggest challenge — ahead of rising product prices and parts shortages.

The skilled trades workforce has been aging for years, and the pace of attrition is only accelerating. A significant portion of experienced parts and service professionals at dealerships are within five to 10 years of retirement, and the incoming talent pool isn't arriving with the same depth of product knowledge or institutional familiarity.

That's not a criticism of younger workers. The equipment has gotten more complex, the brands have multiplied, and the expectation that someone new can absorb 20 years of experience through shadowing is no longer realistic.

As dealer groups get larger through acquisition, the risk grows too. More rooftops, more brands, and more variation across the network make it harder to rely on experience that lives in just a few people.

The question is no longer whether this knowledge will leave, but whether the operation is ready when it does.

What Actually Replaces Experience

While training and better hiring help, they don't solve the core issue: decisions that used to be made based on years of experience and intuition need to be made by something that scales and doesn't retire.

In practice, that means moving stocking decisions from individual judgment to data-driven planning with systems that track demand patterns, account for seasonality, factor in equipment age and duty cycles, and flag when inventory levels are drifting out of alignment. The idea isn’t to replace the people behind the counter, but to give them something to work with that doesn't depend on them having seen the same situation 10 times before.

It's also what dealers are already asking for — in the same DIS survey, parts ordering ranked as the number one process they want automated, with 56% naming it their top priority.

What to Do Before the Cake Gets Cut

The dealers in the best position right now are the ones who are turning experience into process. As well as documenting what they can, they’re implementing systems that make individual expertise less of a single point of failure.

If you have a 20-year parts manager who's a few years from retirement, you need to make sure what they know isn't required to keep the operation running the way it should.

That starts with an honest look at how many stocking and pricing decisions in your operation are still driven by experience and instinct and what it would take to change that — before that knowledge walks out the door.
