摘要：
SELF-LEVELING LINKAGE WHICH IS EFFECTIVE TO POSITION A MOWER FROM THE UNDERSIDE OF A TRACTOR BY MEANS OF A SINGLE ROCKSHAFT GENERALLY PARALLEL WITH THE GROUND. THE LINKAGE COMPRISES FRONT AND REAR LIFT LINKS CONNECTED AT THEIR UPPER ENDS TO OPPOSITE ENDS OF A LIBRATORY LEVER WHICH IS CONNECTED INTERMEDIATE ITS ENDS TO THE ROCKSHAFT. THE LOWER ENDS OF THE LIFT LINKS ARE CONNECTED TO THE FRONT AND REAR ENDS OF THE MOWER AND THE REAR LINKS ARE PIVOTED INTERMEDIATE THEIR ENDS TO A PAIR OF DRAFT LINKS INTERMEDI-
ATE THEIR ENDS. THE DRAFT LINKS ARE PIVOTED AT THEIR FORWARD ENDS TO THE FORWARD END OF THE MOWER COAXIAL WITH THE LOWER ENDS OF THE FRONT LIFT LINKS AND EXTEND OVER THE MOWER AND HAVE REAR END PORTIONS PIVOTED TO THE TRACKS BEHIND THE MOWER. THE AMOUNT OF LIFT OF THE FRONT OF THE MOWER BY THE FRONT LINKS IS CONCURRENTLY EQUALIZED BY THE LINKAGE IN LIFTING THE REAR END OF THE MOWER.
