Ever since 1946, Zetor tractors have used Zetor's
own engines. The Proxima series is equipped with the new
generation of
Zetor engines. New engines bring more power and much higher torque,
along with smooth run and excellent cold weather
starting. The large
displacement of the new engines is based on proven higher-horsepower
Forterra series engines, with horsepower
designed to meet the needs of
Proxima 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 2 emission
regulations without affecting
their highly regarded fuel
economy. At the same time, Proxima engines maintain proven
all-mechanical
controls, so future servicing is greatly minimized and
simplified.

An air compressor is standard on all cab tractors and optional on open
station models. You can use it to inflate tires, or
to run various equipment. On cab models, the same air system also controls the
rear differential lock and the mechanical
front wheel drive clutch. An ait system in these applications, unlike hydraulic systems,
is simple and maintenance-free.

Zetor Proxima tractors are equiped with a large all-copper radiator.
New radiators are very efficient, and require less frequent cleaning.
On tractors with air conditioning, the condender slides to
the side, to make cleaning easy.
|
Most Proxima tractors are used with front loaders. The dual clutch
features 12"
heavy-duty engine clutch plate with industrial-grade cerametallic
lining, especially suitable for loader work.
High mass flywheel
dissipates heat efficiently. Engine clutch does not require any
adjustment. Heavy-duty throwout bearings are
designed for the life of
the engine.
The hydraulic clutch controls were redesigned for the Proxima. Special
geometry of
the clutch pedal considerably reduces pedal effort. Low
pedal force effort allows smooth and soft clutch engagement.
|
All Zetor engines have wet sleeves for easy and inexpensive overhauls.
No special tools are required for engine
repairs.
|
Proxima engines use precisely balanced components to
ensure
a smooth, vibration-free run. In addition, this Zetor engine
family has traditionally been equipped with two precision-machined
balancer shafts running in needle bearings, further reducing engine
vibrations at any engine speed.

The large capacity fuel tank with ground level fueling.

The side-mounted muffler is
standard on all cab models. The operator’s view is not restricted.
All Proxima engines are equipped with a glow plug in
each cylinder,
automatically controlled by the key switch. After a few
seconds of preheating, the engine will start immediately, even on very
cold
winter days, without the help of a block heater. This system is
far superior to other starting aids and is totally maintenance-
free.
|
Reliable Zetor in-line injection pump is superior to any rotary pump
design and is
designed for lifetime service-free operation. The in-line injection
pump, together with high capacity battery (950
CCA) and efficient glow
plug in each cylinder provide outstanding cold weather start.
Zetor injection pumps also traditionally
tolerate fuels of various
quality - a major advantage in real-life farming environment. High
reliability and ease of servicing of
Zetor injection equipment is
important contributing factor to low operating costs of Zetor Proxima
engines.
Zetor injection
pumps carry 5-year factory warranty.
|
For extremely cold climates, a block heater is
available as optional equipment.
|
|
Proxima engines have very high torque
backup (over 40%), to reduce the
need for down shifting. The engine horsepower stays constant through a
broad range of engine
speed.
