The Service Manual for Valtra A53, A63, A73

 

 tractors 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. 
 
The Service Manual will be continually updated with new revised pages which should be 
inserted in the manual. Alterations and additions will first appear as service bulletins. 
 
Only genuine Valtra spare parts should be used to ensure the best possible function of the 
machine. Certain operations should be carried out with the aid of special tools designed by 
Valtra.
