When sourcing this classic model, you must verify the engine type, typically the Perkins AD4.203 diesel engine, known for its 58.3 HP output. Ensure the transmission system is either the standard 8-speed sliding gear or the Multi-Power version depending on your needs. For hydraulic performance, confirm the lift capacity at the rear linkage is approximately 1,587 kg (3,500 lbs). If purchasing refurbished units, request a compression test report for the cylinders and a dyno test to verify actual power output.
