ENGINE DETAIL
The Zetor 7321 features a turbocharged 3.9L diesel engine producing 78hp at a rated RPM of 2200, which offers a good power-to-weight ratio for farm tasks. Its 17:1 compression ratio enhances fuel efficiency while the 12V starter ensures reliable ignition in various conditions. However, its 4-cylinder configuration may limit torque output compared to higher-cylinder models, making it less ideal for heavy-duty applications but suitable for moderate agricultural use.

ZETOR 7321 ENGINE
The Zetor 7321 is equipped with a robust 3.9L 4-cylinder diesel engine, delivering reliable power and torque for various agricultural tasks. With a fuel tank capacity of 32 gallons (121.1 liters), it allows for extended operation between fill-ups, minimizing downtime. However, its relatively smaller engine displacement may result in less power compared to higher-capacity competitors, making it ideal for lighter applications or smaller farms.

TRANSMISSION 1
The Zetor 7321 features a synchro mesh transmission with 10 forward and 2 reverse gears, providing improved shifting efficiency and operator comfort during varying tasks and terrain. The hydraulic-operated 304.8mm cerametallic disc clutch allows for enhanced durability and performance under high-stress conditions, though it may require more precise engagement to avoid wear. Ideal for medium-scale agricultural operations, its setup allows for flexible maneuvering in tight spaces while maintaining robust power delivery.

TRANSMISSION 2
The Zetor 7321 features a mechanical shuttle transmission with 10 forward and reverse gears, offering versatile speed control for various agricultural tasks. This setup enhances maneuverability in tight spaces, making it suitable for both fieldwork and transport duties. However, operators must be accustomed to manual shifting, which may require more skill compared to fully automated systems.

| Gears | 10 forward and reverse |
MECHANICAL
The Zetor 7321's 4x2 2WD chassis provides good maneuverability for light agricultural tasks but may struggle in heavy tillage or uneven terrain due to limited traction. Its power steering enhances ease of operation, while the hydraulic wet disc brakes ensure consistent stopping power under various conditions. The optional air-conditioned cab adds comfort for extended use, making it suitable for short to medium agricultural operations, although it may not be ideal for rougher terrain where 4WD would offer significant advantages.

ZETOR 7321 TIRES
The Zetor 7321, equipped with 9.00-16 agricultural front tires and 18.4R34 rear tires, offers a balance of maneuverability and traction, well-suited for tasks requiring agility in tight spaces while maintaining stability under heavier loads. The tire combination maximizes ground contact and improves soil compaction management, essential for effective tillage and planting. However, operators may face challenges in extreme muddy conditions due to the front tire's narrower profile, which could reduce flotation.
