RESEARCH OF INSTALLATION OF PLASTING PLATE TRACTOR-PROMPT
To increase the thickness of chips, reduce the time spent, the ways of filling the bucket and the performance of scrapers (especially self-propelled wheeled), pusher tractors are used (figure 1), the number of which depends on the scraper type, bucket capacity and transport distance (1 pusher for 2... 16 scrapers ). The length of the bucket filling path when the scraper and the pusher are working together in sandy loamy and loamy soils is reduced to 10... 12 m, in clay soils - up to 15... 18 m with a normal filling path length of 22... 26 m. At the same time chip thickness is increased by 20... 25%. Pusher tractor is especially effective in the development of dense and heavy soils, when the scraper tractor's efforts are not enough to fill the bucket effectively.
