Improving the Reliability of the Scraper-Bunker Peat Harvester
Cases of failures of peat scraper-bunker harvesting machines are analyzed. It has been proven, that the main cause of failures is the stumpiness of the peat deposit. When interacting with the stump, there is a sharp increase in the load on all elements of the transmission of the machine, which leads...
