Oddiy haydov agregatining tortish qarshiligi, N:

R_a.pl = mgf_m + k_pl aV_pl + s aV_pl ².
R_{a. il}= 700·9,81 ·0,15+0,7·10⁵ ·0,3·1,05+0,8·1600·0,3·1,05 ·1,5²=24000 N.
Traktorning II uzatmasida P_il.n= 2800 kg.k.= 28000 N.
Traktorning ilmoqdagi nominal tortish kuchidan foydalanish koeffitsientini aniqlaymiz:
η_il =R_a.pl / P_il.n = 24000/28000 = 0,86
Maksimal tortish quvvatidan foydalanish koeffitsienti
= R_a.pl /N_il.max= 24000·1,5/42000 = 0,86
Motorining ushbu yuklamada effektiv quvvati, kVt:
N_e= = = 57,8
Traktorning FIK: η_t = N_il/N_e =36 / 57,8 = 0,62.
