The invention relates to the field of mechanical equipment, in particular to a drive seat damping structure of a light caterpillar tractor. According to the technical scheme, the drive seat damping structure of the light caterpillar tractor comprises a rack. The rack comprises a chassis rack and a left-and-right support, the chassis rack is used for connecting an engine and a speed changing box, the left-and-right support is located above the chassis rack and used for being connected with a driving control board, and the chassis rack and the left-and-right support are connected through a damping device in the vertical direction. According to the drive seat damping structure of the light caterpillar tractor, it is ensured that the engine is positioned accurately and reliably in the installation process under the situation that cost is not increased; under the tractor running state, the vibration caused by the engine and vibration caused by a rough road surface are reduced, the effect on the body injuries and safety driving of a driver on the driving control board is reduced, and meanwhile damage of components on the driving control board is lowered.
