Abstract
1,091,532. Tractor power lift mechanisms. MASSEY-FERGUSON Inc. April 12, 1965 [April 13, 1964] , No. 15390/65. Addition to 1,030,031. Heading A1P. A tractor power lift mechanism incorporating two rams 13, 14 is arranged to permit a limited relative movement between the draft links 11, 12 to allow use of wide implements on sloping ground. A transverse bar 25 has lift arm 17 secured to it and rotatably mounts lift arm 18 associated with a locking arm 26 secured to the bar 25. A member 27 mounted in the lift arm 18 engages in a hole in the locking arm 26 and is rotatable to either make the lift arm 18 non-rotatable with respect to the shaft 25, or to allow it limited pivotal movement on the shaft.
