The application rate error in seed drill field operation due to drive wheel tire inflation change occurs because:
Options:
-
(A) Under-inflated drive tires have smaller rolling radius, rotating more turns per distance and over-seeding
-
(B) Over-inflated tires attract seed static charge
-
(C) Tire pressure changes seed weight
-
