The verdict
The CAT 966H brings a cleaner Tier 3 engine, better cab ergonomics, and typically 8-12% fuel savings over the older 966G. The CAT 966 (pre-H) is R400-800k cheaper on the used market and mechanically simpler to repair. For heavy annual hours (>2000/yr), the 966H's fuel savings pay back the price gap within 3 years. For light use, the older 966 is a bargain.
Low-hours operators, price-sensitive buyers, quarries with simple maintenance shops.
Heavy-hours fleet, operators who value cab time, buyers keeping the machine 5+ years.
