Cat 307 expert review
Overview
The Cat 307 is a compact radiator excavator weighing between ~7.27 t and ~7.6 t, powered by a 37.7 kW (50.6 hp) C2.4 Turbo Tier 4 Final engine. It digs up to ~4.12 m, reaches ~6.67 m, and has a transport width of ~2.2 m.
Pros Compact width (~2.2 m) fits tight job zones.
Smart hydraulics and service layout reduce cost and downtime.
Smart hydraulics and service layout reduce cost and downtime.
Cons Weight (~7.6 t) requires ground prep and trailer planning.
Mid-level power may limit performance in tough digging conditions.
Mid-level power may limit performance in tough digging conditions.
Performance & Efficiency
Variable displacement hydraulics, auto-idle, and auto-shutdown deliver efficient performance. Stick-steer travel and AC cab improve operator comfort.
In Comparison
Compared to smaller 305 or 306 models, you get more reach and comfort with only minimal size increase. More agile and cost-effective than full-size excavators.
Verdict
Well-balanced for compact excavation and multi-use jobs. Ideal for rental and urban applications. Not the one for heavy-duty rock work or maximum hydraulic output.
