:quality(50)/59614/28833737-7fd2-47f5-9074-9b04c05d4d7f.png)
The Cat 966 (2014–2025) in H and M trims is a production-class loader that balances high-capacity bulk work with reliable handling. Operating weights run 23.5–24.6 t, buckets range 3.2–4.2 m³, and net power sits around 195–239 kW (261–321 hp) from Cat’s C9.3 ACERT or C9.3B diesel. The H trim is Tier 4 Interim, rugged and straightforward, while the M is Tier 4 Final, bringing integrated Payload weighing, OptiShift-like drivetrain refinements, and more precise electro-hydraulic controls.

Cat 966 expert review
Overview
Heavy-duty loader for quarry, aggregate, and bulk handling. H trim is tough and simple; M trim adds Payload, tech upgrades, and fuel efficiency improvements.
M adds Payload and parallel lift improvements.
M electronics require skilled servicing.
Performance & Efficiency
Both trims are fast and stable. M's Smart Mode optimizes fuel use and reduces operator fatigue. H is predictable and service-friendly for remote work.
In Comparison
Volvo L150H matches lift but rides smoother; Komatsu WA470-8 has more bucket volume but heavier frame.
Verdict
H for tough-site reliability, M for tech integration and efficiency gains.
