Introduction
Valmet 905 Agricultural Tractor
The Valmet 905 is a row-crop tractor belonging to the 805 series, manufactured between 1984 and 1991. Designed for demanding agricultural operations, this model integrates a robust six-cylinder diesel engine with a standard four-wheel-drive configuration.
Engine and Performance
The tractor is powered by the Valmet D66D9 diesel engine, a liquid-cooled, six-cylinder unit with a displacement of 6.6 liters (402.8 ci). It utilizes direct injection and an intake air heater for cold-start reliability. The engine delivers 105 hp (78.3 kW) at a rated speed of 2100 RPM, with a compression ratio of 17:1.
Transmission and Drivetrain
The transmission system provides two main configurations: a standard 8-speed synchromesh gearbox (8 forward and 4 reverse) or an optional 16-speed two-speed powershift (16 forward and 8 reverse). Both options utilize a 330mm dry disc clutch. The drivetrain features four-wheel drive, power steering, and an electro-hydraulic rear differential lock to ensure traction in varying field conditions.
Hydraulics and PTO
The hydraulic system operates at a pressure of 2611 psi (180.0 bar) with a pump flow capacity of 12.7 gpm (48.1 lpm). The rear hitch provides a significant lift capacity of 12,590 lbs (5,710 kg). The independent rear PTO supports dual speeds of 540 and 1000 RPM, allowing for versatile implement integration.
Dimensions and Operator Environment
With a wheelbase of 100.8 inches (256 cm) and a total weight of 9,766 lbs (4,429 kg), the tractor is built for stability. It is equipped with a standard cabin, with optional air-conditioning available for operator comfort. The machine utilizes hydraulic wet disc brakes for consistent stopping power.
Conclusion
The Valmet 905 is a durable and versatile utility tractor suited for varied field tasks, offering high lifting capacity and flexible transmission choices, making it a reliable asset for agricultural operations from the mid-1980s to early 1990s.
