- Elevator: 20–40 yr
- Tractor: 15–50 yr

## What that means over time

*Assuming the typical lifespan above and immediate replacement.*

| --- | --- |
| Per year | 0.04 replacements |
| Over 10 years | 1 of them |
| Over a 30-year mortgage | 1.2 of them |

> Lifespans are medians under ordinary use, not guarantees. Maintenance, how hard it is used, and build quality move individual examples a long way in both directions — which is why the range above is as wide as it is.
