Operational Readiness of the Hidraulic Sub-Aggregates Tractor-Cultivator

Abstract

The paper consist specifics relating to the operation and maintenance of the hydraulic sub-aggregates tractor-cultivator. As the works in the seasonal character of agriculture and must be done in strictly defined time intervals, any notice element aggregates tractor-cultivator, may bring into question the performance of primary processing soil and great material losses. Therefore, the aggregate of the tractorcultivator requires very high reliability. The paper discusses the operational readiness of tractors as a measure of the effectiveness and quality of its maintenance. Also in the paper are the results of the research on the availability of aggregate tractor- cultivator on one agricultural good.

U radu su date specifičnosti koje se odnose na eksploataciju i održavanje hidrauličnog podsistema agregata traktor-setvospremač. Kako su radovi u poljoprivredi sezonskog karaktera i moraju se obaviti u strogo termirinam vremenskim intervalima, to bilo koji otkaz elementa agregata traktor-setvospreemač, može dovesti u pitanje obavljanje dopunske obrade zemljišta, odnosno do velikih materijalnih gubitaka. Zbog toga se od agregata traktor-setvospremač zahteva i vrlo visoka operativna gotovost. U radu je razmatrana operativna gotovost kao merilo efektivnosti traktora i setvospremača, odnosno kvaliteta njihovog održavanja. Takođe u radu su dati rezultati istraživanja operativne gotovosti agregata traktor-setvospremač na jednom poljoprivrednom dobru.
