To the reader
The Workshop manual is intended to be a practical reference source to be used in workshop. The repair
instructions in the manual are based on methods which have been worked out in practice during normal workshop
conditions and which are based on the use of special tools from the manufacturer when stated in the instructions.
The manual also contains descriptions of the design and function of the components.
Detailed maintenance instructions can be found in Operator’s manual.
Wiring diagrams can be found in a separate publication for wiring diagrams.
The Workshop manual is divided into groups (00–21) following the spare parts catalogue numbering. Some spare
parts catalogue groups have been omitted as unnecessary.
Due to the continual development of the products, the content of this manual may not always correspond to the
new product. Therefore, we retain the right to make alterations without prior notification.
Use only genuine AGCO Parts spare parts for optimum performance. Certain operations should be carried out with
the aid of special tools designed by Valtra.

Tyre dimensions according to STRO norms.
Masses
With tyres 600/65R28, 710/70R38
Total mass with full fuel tank and without ballast weights (kg) 7300
Front axle mass (kg) 2920 (40%)
Rear axle mass (kg) 4380 (60%)
Maximum permissible axle loading
The data is valid for tractors with standard track widths and regardless of tyre limitations.
DANGER: In offroad conditions, the allowed driving speed with maximum front axle loading is 10 km/h.
If the driving speed is faster than this in offroad conditions, the allowed front axle loading is smaller.
Maximum front axle loading at maximum driving speed (kg) 5500
Maximum front axle loading at working conditions: offroad and with
driving speed 10 km/h (kg)
8500
Maximum rear axle loading (kg) 9000
Total weight (kg) 13 500
NOTE: The permissible wheel load can reduce the maximum permissible axle load.
IMPORTANT: On 50 km/h models and when driving at the maximum speed, the tyre loading is smaller. For
information on tyre pressure, see the tyre manufacturer's catalogue.
Tyres
The tyre markings are explained in the following table, tyre 650/65R42 as an example. See tyre manufacturer's
documentation for more details.
650 Tyre section width (inches or millimetres)
65 Aspect ratio
R Construction (R: radial; -: diagonal; B: bias belted)
42 Nominal rim diameter (inches)
