Abstract
Influence of arable land size on utilization degree, number of working hours during a year and on a total tractor power for ten chosen family farms was investigated in this paper. Family farms which have larger arable land at their disposal considerably better utilize agricultural aggregates, especially A category tractors whereas at the same time utilization of B category tractors is significantly less, so, coefficient of correlation amounts to R=0,8635 and determination R2=0,7457. Suitable coefficients for B category tractors are R=0,9739 i.e. R2=0,948. Influence of arable land size is considerably expressed on utilization of higher categories tractor capacities. Influence of arable land size on required number of tractor working hours is defined by correlation coefficient of R=0,9097 and determination coefficient R2=0,7588.
