Specification

ENGINE
Designed without electronics and additional fuel admixtures, the factory engines of ZETOR dominate over competition through simple service and high level of reliability. They feature a good deal of torque margin (over 34 %), which reduces the need of advance gear shifting. Engine output remains constant within a wide range of rpm speeds.

GEARBOX
The tractor is equipped with a fully synchronized four-gear transmission system with three reduced gears and a reverse gear. Number of gears is 12 + 12.

HYDRAULICS
The Major Model makes use of hydraulics with mechanical control. It features not only high lifting force, but also a smooth regulation of startups, including the hydraulic lock function while tools are being transported. The tractor is fitted with a two-sectional or single-sectional extra distributor with reverse quick-action clutch for wastes from the rotary hydraulic motor.

CABIN
Comfortable in view of practical applications. enough space and ergonomic design of controls make the working with tractor easier.
