Abstract
Implements designed for attachment to a lawn and garden tractor include elongate attaching frames having the implement tool connected to first ends of the frames and transport wheels located so that the weight of the implement is distributed approximately half on opposite sides of the wheel axes so that the implement may be easily pushed about on the wheels during mounting and dismounting the implement to and from the tractor frame. Attachment brackets and lift links of the implements are engageable with attachment pins and lift crank arms of the tractor without necessitating any lifting of the implement. Also with driven implements, the drive belts are arranged on or stored with the implements so that the tractor drive may be easily and correctly connected.
