Best way to use these resources

For a buy vs. rent decision, compare these 6 things:

1. Job size and machine class needed
2. Expected annual usage hours
3. Rental cost over time
4. Purchase cost + financing + maintenance
5. Resale value after ownership
6. Transport, downtime, and attachment needs

---

Simple rule of thumb

• Rent if you need the excavator occasionally, for short-term jobs, or need different sizes often.
• Buy if you’ll use it frequently, have steady utilization, and can keep it working on multiple projects.
