Abstract
Abstract A frame for a tractor includes a pair of spaced plates having upwardly extending portions with ears fixed thereto, for a mounting of a roll-over protective structure or tractor implement means thereto. Additional plates may be fixed to these spaced plates along the upwardly extending portions thereof, and, with apertures properly provided therein, such additional plates allow the mounting of implement means thereon. Such upwardly extending portions and additional plates may be eliminated completely, if desired.
