An auxiliary tractor seat for providing additional seating in a tractor cabin is provided herein. The auxiliary tractor seat includes a mounting plate defining one or more mounting holes, configured to receive an auxiliary tractor seat bolt, so as to couple the auxiliary tractor seat to tractor seat. A base plate is coupled to the mounting plate so as to provide a substantially flat seating surface. A lower seat back coupled to at least one of the mounting plate and the base plate, an upper seat back at least partially disposed above the lower seat back, and a hinge coupled to the lower seat back and the upper seat back so as to permit the upper seat back to transition from an upright position to a horizontal position. The auxiliary tractor seat is coupled to the tractor seat such that suspension supports the auxiliary seat and provides shock absorption.

A seating assembly includes a seat. A front assembly bracket is coupled to an underside of the seat. A rearward retention member defines a receiving aperture to receive a front cross-tube. A polymeric overmold is disposed over the rearward retention member. A forward retention member is operable between open and closed positions and is disposed proximate the rearward retention member. A rear assembly bracket includes a tab end operably coupled with the seat. A rounded body is configured to close engage a rear cross-tube. A fastener end is configured to secure the rear assembly bracket against the cross-tube.
