dIn the paper some new solutions for the developing farm machinery planing
system for agricultural extension needs was presented. Worked out simulatio
n model compared with IMAG-ORSPEL systems ensures more facilities for the e
nd users. It's ensures modern graphical interface which let better structur
e the problems of farm machinery planing. Mutually verifying specific and s
tandard data bases let compare specific and standard parameters ensuring mo
re precise input. Contribution of user to the input data ensure two methods
of calculation of farm machinery use. Flexible system of amortisation calc
ulation let farmer choose appropriate way for his specific conditions of re
placement of farm equipment. Procedures of the balancing input and recourse
s of time let detect components and periods concerning labour peak problems
