Excavator Class Comparison for Residential Foundations
When selecting an excavator for basement excavation, particularly for homes averaging 1,450 square feet with typical depths around 6 feet, contractors often debate between the 160-class and 200-class machines. The 160-class excavator, such as the John Deere 160D LC or Hitachi ZX160, offers easier transport, lower operating costs, and sufficient power for most residential applications. The 200-class, including models like the Deere 200D LC or Hitachi ZX200, provides greater reach, bucket capacity, and faster cycle times—but at the cost of increased weight, fuel consumption, and transport complexity.
Terminology Clarification
The 160-class excavator is significantly easier to move between jobsites, especially when using tandem or tri-axle trucks with 25-ton tag trailers. In contrast, the 200-class often requires a lowboy trailer and may exceed legal weight limits depending on local DOT regulations. For contractors working in subdivisions or urban lots with limited access, the smaller footprint and lighter weight of the 160-class machine can be a decisive advantage.
In Colorado, a contractor reported that his 210-class excavator required special scheduling for transport and often delayed concrete crews due to space constraints. Meanwhile, his 160-class unit could be repositioned quickly, allowing for smoother coordination with other trades.
Performance and Productivity Differences
While the 200-class excavator can carry a larger bucket—typically 1.5 cubic yards compared to 0.9–1.0 cubic yards on a 160-class—it doesn’t always translate to double the productivity. For basement holes ranging from 400 to 700 cubic yards, the difference in dig time may be only 1–2 hours. If the operator is skilled and the site is well-prepared, a 160-class machine can complete the job efficiently.
Fuel consumption also plays a role. A Hitachi ZX160 may burn 6–8 gallons per hour under load, while a Volvo EC235 or Deere 200-class machine could consume 10–12 gallons per hour. Over time, this difference impacts operating costs, especially for contractors digging multiple basements per week.
Dealer Support and Financing Strategy
Choosing a machine through a reputable dealer offers advantages beyond equipment quality. Many contractors prefer RPO agreements, where up to 90% of rental payments apply toward purchase. Dealers often provide better financing rates (around 4% for used equipment), warranty support, and access to parts inventory. One Alabama-based contractor emphasized that his long-term relationship with a dealer allowed him to secure a well-maintained rental unit with low hours and no Tier IV emissions system—saving both money and maintenance headaches.
Operator Technique and Job Setup
Machine size is only part of the equation. A well-planned excavation strategy—such as staging spoil piles, coordinating truck loading, and sequencing utility trenching—can dramatically improve efficiency. One Pennsylvania operator noted that his 160-class machine performed just as well as larger units when paired with a disciplined workflow and experienced crew.

Terminology Clarification
- Excavator class: Refers to the operating weight category, typically in metric tons (e.g., 16-ton vs. 20-ton).
- Cycle time: The time it takes to complete one full dig-load-dump-return sequence.
- Compact radius: A design feature that reduces tail swing, improving maneuverability in tight spaces.
- RPO (Rental Purchase Option): A financing model where rental payments contribute toward eventual ownership.
- Tag trailer: A trailer without a detachable gooseneck, often used for hauling mid-size equipment.

Final Recommendations
- For frequent moves and tight lots, choose a 160-class excavator for its mobility and lower operating costs.
- If digging deep basements or handling large volumes, a 200-class may offer time savings—but consider transport logistics.
- Evaluate fuel burn, bucket capacity, and cycle time in the context of your average job size.
- Build strong relationships with dealers to access flexible financing and reliable service.
- Train operators to maximize efficiency regardless of machine size.
