CAT 320D3
Pros
- Strong engine performance for a 20-ton class excavator: 134 HP gross (100 kW), ~114 HP net. Great for heavy digging and lifting tasks.
- Typically well-insulated, ergonomically arranged operator cab with adjustable suspension seat, good visibility, and modern controls.
- Selectable power modes (Power, Smart, Eco) improve fuel efficiency depending on task.
SANY SY20U
Pros
- Zero-tail swing design makes it ideal for tight, confined job sites such as urban construction, landscaping, housing sites, and utilities work.
- Load-sensing hydraulics deliver smooth flow and good fuel use for a mini excavator of this size.
- • Works well for small earthmoving, trenching, irrigation, and utility trench jobs where a bigger excavator isn’t practical.
