Abstract
Possibility of self-excitation of wheeled tractor frame oscillations in longitudinal plane during the operation in tractive mode is theoretically substantiated. Dependence of rolling radius of a pneumatic wheel on vertical load and on driving moment level, mathematical model describing pneumatic wheel rolling under variable vertical load and two-mass lineal model describing tractor frame oscillations in longitudinal plane are used.
