2025 Caterpillar Medium Wheel Loaders 966

High Production for Efficient Operation

The Cat® 966 Wheel Loader brings premium performance with simple-to-use technologies, helping to boost operator efficiencies and deliver consistent high bucket fill factors, resulting in highly efficient productivity. Long service intervals help to reduce your downtime. This machine is designed to meet emission standards without interrupting operation, delivering great performance, reliability, durability, and versatility, resulting in a machine that is built to meet your needs.

Features may include:
  • Auto front differential lock removes the burden from the operator by automatically engaging the differential lock to improve overall traction.
  • Equipped with automatic Cat regeneration system, Cat Clean Emissions Module (CEM) with Diesel Particulate Filter (DPF), and Diesel Exhaust Fluid (DEF) tank and pump.
  • Full-flow hydraulic filtration system with additional kidney-loop filtration improves hydraulic system reliability and component life.
  • Improve machine efficiency, productivity, utilization and reduce per-unit costs.
  • Tire Pressure Monitoring System allows operator to easily monitor tire pressure from the main machine display helping to improve machine performance, operator ride and operating costs.
