Match the words with their meaning
1. The engine
2. The transmission
3. The running gear
4. The driveline
a. converts thermal energy into mechanical energy.
b. is needed for the tractor to move. The rotation of the driving
wheels (or the movements of the tracks) in contact with the
ground is converted into the translator motion of the tractor.
c. comprises a set of mechanisms which transmit the torque
developed by the engine to the driving wheels or tracks and
change the driving torque in magnitude. It includes the clutch,
flexible coupling, gearbox, and rear axle.
d. makes it possible to change the driving torque and the running
speed of the tractor by engaging different pairs of gears. With
the direction of rotation of the engine shaft remaining the same,
it enables the tractor to be put in reverse.

5. The clutch
6. The steering mechanism
7. The flexible coupling
e. serves to disconnect the engine shaft from the
transmission for a short period of time, while the driver
is shifting gears, and also to connect smoothly the flow
of power from the engine to the driving wheels or
tracks when starting the tractor from rest.
f. incorporates elastic elements allowing to connect the
clutch shaft and the transmission drive shaft with a
slight misalignment.
g. serves to change the direction of movement of the
tractor by turning its front wheels (in wheeled tractors)
or by varying the speed of one of the tracks (in crawler
tractors).

Match the words with their meaning
1.the tractor auxiliaries
2. the rear axle mechanisms
3.the working attachments
a. increase the driving torque and transmit it to driving
heels or tracks at right angeles to the drive shaft.
b. include the driver’s cab with a spring-mounted seat
and heating and ventilation equipment, hood, lighting
equipment, tell tales (indicators), horns, etc.
c. of the tractor are used to utilize the useful power of the
tractor engine for various farm tasks. They include the
power take-off shaft, drawbar (hitch device), implementattaching (mounting) system and belt pulley.
