Mower parts fitment lookup
Find the part
that fits your mower.
Type the model number off your machine, or the part number off the old part. We show what fits, what it depends on, and where the claim came from — so you can check it before you spend anything.
Why the serial mattersVerified. Toro lists engine maintenance kit 20234 for this range.
What you can settle here
Four questions, in the order they come up
What part do I need?
Search by the number stamped on the old part, or browse by what the part does.
Will it fit my exact machine?
Fitment is recorded per model and, where it matters, per serial range — not per brand.
Is it OEM or aftermarket?
Every part is labelled, and alternate numbers carry their own evidence rather than being merged.
Where do I buy it?
Links name the retailer. We never quote a price we cannot verify.
Before you search
How to find your model number
Almost every wrong part starts with the wrong number. Mowers carry a model and serial plate, and the two are not interchangeable: the model number tells you which machine you have, and the serial number tells you which production run — which on many mowers changes what fits.
On a walk-behind mower the plate is usually on the housing, or under the control panel. Write down both numbers before you start looking.
The engine has its own numbers, stamped on the engine itself. Filters, plugs, and maintenance kits are chosen from those, not from the mower’s model number.
Worth knowing
One model number can cover several production runs. On the Toro 20340, the blade is the same across both runs Toro publishes — but the engine maintenance kit is not.

Covers and storage

Where this site stands
Current coverage
This site is new and deliberately small. It currently holds 39 parts across 11 verified machines, every one of them checked against the manufacturer’s own parts listings.
We would rather cover one mower properly than a thousand from guesswork. Records we have not verified are visible as unverified rather than dressed up as fact. Last verification pass: August 22, 2026.
