Overview
The Challenger 70C is a powerful crawler tractor featuring a 285 hp Caterpillar 10.5L 6-cylinder turbocharged intercooled diesel engine and a 10-speed full power shift transmission. Built in Peoria, Illinois, this agricultural machine is designed for high-capacity work with a significant 209-gallon fuel tank and a specialized track system providing 6,428 square inches of ground contact.
Ideal Applications
High-Efficiency Field Operations:
Utilizes the 10-speed full power shift transmission and 250 hp PTO capacity to manage demanding agricultural implements while maintaining traction through its crawler drive system.
Soil Compaction Management:
The 30-inch wide tracks distribute the 35,685 lb operating weight to achieve a low ground pressure of 5.6 psi, protecting soil structure during heavy field work.
Large-Scale Farming Productivity:
The massive 209-gallon fuel capacity and 285 hp engine allow for extended operating hours and the power necessary for large-scale agricultural tasks without frequent refueling.
