MASSEY FERGUSON 821 POWER
ENGINES OVERVIEW
The Massey Ferguson 821 tractor's engine options include a 1.3L 4-cylinder gasoline from Peugeot and a 1.0L 2-cylinder diesel from Hanomag, offering versatility in fuel choice. The gasoline engine provides higher power density and faster response, making it suitable for lighter agricultural tasks and quicker field operations, while the diesel option offers better fuel efficiency and torque for heavy-duty applications. A challenge may arise in maintenance costs and fuel availability, impacting operational flexibility depending on local infrastructure and requirements.

MASSEY FERGUSON 821 ENGINES
The Massey Ferguson 821 tractor features a dual-engine option, allowing for versatile applications. The Peugeot 1.3L gasoline engine provides more horsepower and faster response, making it ideal for high-demand tasks, while the Hanomag 1.0L diesel engine offers better fuel efficiency and torque for sustained operations. Consideration must be given to operational costs and maintenance, as the gasoline variant may incur higher fuel expenses compared to the diesel engine's longevity and efficiency in agricultural settings.

TRANSMISSION
The Massey Ferguson 821 features a 5-speed forward and 1-speed reverse gear configuration, providing versatility for various field operations with adequate torque control. The oil capacity of 7.4 quarts (7.0 liters) suggests a robust lubrication system, essential for maintaining engine longevity under heavy loads. However, it's important to monitor oil levels closely, as inadequate lubrication can lead to mechanical failure, especially during intensive use scenarios.

MASSEY FERGUSON 821 TIRES
The Massey Ferguson 821 features Ag front tires with a size of 4.00-15 and rear tires in either 8-24 or 9-28 configurations, offering flexibility in load capacity and traction depending on the terrain. The choice of rear tire sizes allows for increased stability and improved flotation in soft or uneven ground conditions, which is advantageous for tillage and planting operations. However, operators must consider the potential trade-off in maneuverability at higher speeds due to the larger rear tire options.
