Mini Excavator comparison
CAT 305 vs. John Deere 35G
Last reviewed . We review this page periodically for accuracy.
Quick answer
These are two different size classes: the CAT 305 is a 5-ton-class excavator (~45 hp net, ~12,700 lb) while the John Deere 35G is a 3.5-ton machine (~23.3 hp net, ~7,760 lb). The 305 digs deeper and pushes harder; the 35G is far lighter and easier to transport. Match the class to your work before comparing brands.
Key differences at a glance
- The CAT 305 is a 5-ton class; the 35G is a 3.5-ton class — a full size tier apart
- Power: ~45 hp net (305 CR) vs. ~23.3 hp net (35G)
- Dig depth: ~134.6 in std stick (305 CR) vs. ~120 in std arm (35G)
- Weight: ~12,688 lb (305 CR, cab) vs. ~7,760 lb (35G, canopy, std arm) — very different transport needs

Choose the CAT 305 if
- You need 5-ton-class dig depth, reach, and pushing power
- Your work includes deeper trenching and heavier excavation
- You can transport a machine around 12,700 lb and want Cat dealer support
Choose the John Deere 35G if
- You want a light, transportable 3.5-ton utility machine
- Your work is residential, landscaping, and utility trenching
- You prefer the John Deere dealer network and lower running weight
What both machines share
- Both are conventional compact excavators; for tight sites, cross-shop a zero-tail-swing model like the Kubota U35
- Inspect undercarriage, hydraulics, and pins/bushings, and verify auxiliary hydraulics for attachments
- Confirm arm/stick and counterweight configuration, which change both depth and weight
The verdict
This is a size-class decision: buy the CAT 305 if you genuinely need 5-ton capability, and the John Deere 35G if a lighter, more transportable 3.5-ton machine fits the work. Don't overbuy weight you then have to haul and pay for.
