More than a million Zetor Range 1 tractors, one of the most dependable tractor designs, are on the job in just about every part of the world. The new generationof Zetor Range 1 tractors is the"Silver"series.

The new models have been further refined. Every model combines the heavy, tough, reliable and easy-to-service Zetor chassis with updated, more powerful, extremely fuel efficient, cleaner burning, state of the art engines, updated or new transmissions with easier shifting, new heavier front and rear axles, all-new hood, updated controls, more powerful hydraulic systems, more efficient brakes and a wide range of other improvements. New models also have simplified maintenance and extended service intervals.

What did not change is the basic Zetor Range 1 concept: Exceptional value for the money.

The open station models are all-mechanical tractors, thoroughly engineered using up-to-date technology in every aspect, while emphasizing the highest possible reliability and very easy and inexpensive servicing during their entire life.

Even the cab models are still basically all-mechanical design, but use some electric or hydraulic controls to enhance the comfort. Minimizing the number of mechanical controls penetrating the inside of the cab also keeps the cab well sealed and quiet.

The new Zetor "Silver" series are general purpose tractors in 70 to 107 engine horsepower range (63 to 93 PTO horsepower)

Engine:

Ever since 1946, Zetor tractors have used Zetor's own engines. The "Silver"series tractors are equipped with the new generation of Zetor engines. New engines bring more power, high torque, along with smooth run and excellent cold weather starting. The large displacement of the new engines is based on proven higher-horsepower For-terra series engines, with horsepower reduced to meet the needs of mid-size tractors. This family of Zetor engines has become legendary during their 15 years of production for their reliability, extremely long life and easy servicing.

The new engines are product of quality engineering and decades of Zetor engine design expertise. Using state-of-the-art engine technology, the new engines meet EPA Tier 3 emission regulations without affecting their highly regarded fuel economy. At the same time, our engines maintain proven all-mechanical controls, so future servicing is greatly minimized and simplified.

Transmission:

The "20/40" series tractors come standard with smooth shifting fully synchronized mechanical shuttle transmission. It has 12 speeds forward and 12 reverse and improves the productivity of loader work dramatically. Optional high speed version of 4WD models is equipped with increased travel speed (24 mph top speed), to shorten travel times between work sites.

The "50" series tractors are equipped with all-new high speed 16/16 synchro-shuttle transmission with two-speed power shift and hydraulic PTO clutch.

Open station tractors also use a wide, comfortable platform, supported on special rubber blocks. The platform and the seat are five inches lower than on cab models. The roll bar can be folded in seconds.

Brakes:

Wet disc brakes are highly efficient, yet engage very smoothly. They were designed for practically maintenance-free life. Due to the large number of plates (eight total) and their superb friction material, the brake wear is minimal. Brakes are cooled and lubricated by a continuous flow of the transmission & hydraulic oil.

All brake controls such as cylinders are newly designed and externally mounted.

PTO:

The PTO on both "20/40" and "50" series is versatile and efficient. The difference between engine and PTO horsepower is kept to a minimum, typically 5-7%.

Independent PTO on "20/40" series tractors is operated by a separate mechanicalPTO clutch, fully independent from the engine clutch. This simple system engages smoothly and precisely and the operator is always in full control of PTO engagement.

All "Silver" series models also have standard ground speed PTO, which makes it possible to reverse the direction of PTO rotation (for example, to reverse the rotation of a post hole digger), a unique Zetor feature. The PTO can be run in reverse even while tractor is not moving. Ground speed PTO also makes it possible to run lowhorsepower implements, such as water pumps or generators, extremely efficiently. For example, you can run your PTO at 540 rpm while engine is at low idle.

Also available on all models: Front 3-point hitch with 3000 lb capacity and front PTO (1000 rpm, 50 HP max.). Front PTO and front 3-point hitch can be mounted separately, or combined. They can also be added later as dealer-installed accessory.

Cab:

Comfortable cabs and platforms have always been a Zetor tradition. The "Silver"series come with an updated, state-of-the-art design, more refined than ever. The spacious cab has a level, uncluttered floor. Large window area provides excellent visibility in all directions. Fully upholstered fenders and thick floor insulation package keep heat and noice out.

Three-Point Hitch and Hydraulic System:

Transmission oil fill and dipstick are at a service-friendly location.

Zetor's heavy-duty 3-point hitch has very high lifting capacity (6,830 lb on most models). Such lifting capacity far exceeds most tractors of the same category. There is even an optional second booster cylinder available for all models, raising the lifting capacity to 9,000 lb.

So, there is ample power to handle even the heaviest implements of the future.

The hitch is adjustable to both Category I and II. The seat position and large window area ensure good visibility of the 3-point hitch and of the drawbar.
