Developed experimental facilities include  tyre test carriage with continuous recording of  input torque, drawbar pull, tyre sinkage and  forward speed. Deflection and contact  characteristics were made using multiple overlay  technique and present universal characteristic of  tyre was modified for a group of tyres. Zero  condition was established on hard surface  highlighting the weakness of specified zero  conditions. Traction prediction equations were  developed and compared with existing models using  mobility number approach. The unique values of  optimum normal load, maximum drawbar pull and  optimum pull to weight ratio were determined at 20,  25 and 30 per cent slip. Selection of optimum size  tyre for tractors on the basis of weight power  utilization and soil tyre interface was also done.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783843357456\"\u003e\u003ch3\u003eOptimum tyre size on basis of weight power utilization and soil tyre interface for maximum pulling ability\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783843357456","offer_id":39497058648157,"sku":"9783843357456","price":79.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/b32c4721-14be-424b-adb8-80520d07e618.jpg?v=1737266387","url":"https:\/\/shop.autorenwelt.de\/products\/drawbar-performance-prediction-of-agricultural-tractors-von-ajay-kumar-sharma","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
