Beschreibung
Zusammenfassung:	A riding lawn mower includes a chassis having longitudinal support beam, a drive wheel, an electric motor coupled to the drive wheel, a suspended subframe having a longitudinal subframe beam pivotally coupled to the longitudinal support beam about a pivot axis, and a suspension device coupled between the longitudinal subframe beam and the longitudinal support beam. The longitudinal subframe beam at least partially supports the electric motor. The drive wheel and the electric motor are configured to translate relative to the chassis via the pivotal coupling between the longitudinal support beam and the longitudinal subframe beam.
