Abstract
Abstract A hay baler adapted to be towed by a PTO-equipped tractor to pick up windrowed hay and roll the hay into a cylindrical bale of substantial size and weight. The baler includes a pickup unit, a feed roller, a bale-supporting belt, and a plurality of baleforming belts all power driven from the PTO of the tractor. The power is transmitted through a mechanical drive train including an improved gear box unit and an improved mounting system for the unit.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
201 words
In an implement adapted to be towed behind a PTO-equipped tractor and having power driveable components, the improvement comprising: a frame including a pair of forwardly extending side wall members on opposite sides of the longitudinal center line of the implement, a transversely extending brace connected between the side wall members, and a draft tongue structure extending forwardly from the side wall members; power input shafting supported on the draft tongue structure and adapted for transmitting power from the PTO to the implement; a gear box unit having an input shaft coupled to said input shafting and an output shaft extending at substantially a right angle therefrom and projecting through one of said side wall members, said gear box unit including gearing for transmitting drive power from said input shaft to said output shaft through said angle, said gear box unit further including a housing for said gearing and an elongated tubular neck disposed about said output shaft in rigid connection to said housing at one end and to said one side wall member at the other end; and means resiliently suspending said housing from said brace from minimizing transfer of deflection loads between said frame and said gear box unit.
Claim 2
Dependent Claim
201 words
In an implement adapted to be towed behind a PTO-equipped tractor and having power driveable components, the improvement comprising: a frame including a pair of forwardly extending side wall members on opposite sides of the longitudinal center line of the implement, a transversely extending brace connected between the side wall members, and a draft tongue structure extending forwardly from the side wall members; power input shafting supported on the draft tongue structure and adapted for transmitting power from the PTO to the implement; a gear box unit having an input shaft coupled to said input shafting and an output shaft extending at substantially a right angle therefrom and projecting through one of said side wall members, said gear box unit including gearing for transmitting drive power from said input shaft to said output shaft through said angle, said gear box unit further including a housing for said gearing and an elongated tubular neck disposed about said output shaft in rigid connection to said housing at one end and to said one side wall member at the other end; and means resiliently suspending said housing from said brace from minimizing transfer of deflection loads between said frame and said gear box unit.
Claim 3
Dependent Claim
71 words
The subject matter of claim 1, including an output drive member on said output shaft outboard of said one side wall member for transmitting power drive to said components; and a bearing supporting said output shaft within said neck proximate to said one side wall member whereby portions of the driving loads imposed upon said drive member are transferable through said bearing and said neck onto said one side wall member.
Claim 4
Dependent Claim
24 words
The subject matter of claim 1, wherein said means includes a pair of elastomeric members retained compressively between said gearing housing and said brace.
Claim 5
Dependent Claim
20 words
The subject matter of claim 3, wherein said elastomeric members are transversely spaced apart and equidistant from said center line.
Claim 6
Dependent Claim
25 words
The subject matter of claim 1, wherein said input shaft of said gear box unit is disposed within a vertical plane along said center line.
Claim 7
Dependent Claim
32 words
The subject matter of claim 5, wherein said means includes a pair of elastomeric members retained between said gearing housing and said brace in transversely spaced equal distance from said center line.
Claim 8
Dependent Claim
51 words
The subject matter of claim 1, wherein said means includes a support plate rigidly secured to said gearing housing and having an opening defined therethrough, a bolt secured to said brace and projecting through said opening, and a resilient elastomeric annulus disposed on said bolt and compressively seated within said opening.
Claim 9
Dependent Claim
53 words
The subject matter of claim 7, including an output drive member on said output shaft outboard of said one side wall member for transmitting power drive to said components, said output drive member being subjected to driving loads portions of which being transferred through said gear box unit compressively onto said elastomeric annulus.
Claim 10
Dependent Claim
49 words
The subject matter of claim 8, including a bearing supporting said output shaft within said neck proximate to said one side wall member whereby portions of the driving loads imposed upon said output drive member are transferable through said bearing and said neck onto said one side wall member.
Claim 11
Dependent Claim
72 words
The subject matter of claim 1, wherein said means includes a support plate rigidly secured to said gearing housing and a pair of mounting assemblies spaced transversely apart and equidistantly from said center line; each of said assemblies including an opening defined through said support plate, a bolt secured to said brace and projecting through said opening, and a resilient elastomeric annulus disposed on said bolt and compressibly seated within said opening.
Claim 12
Dependent Claim
32 words
The subject matter of claim 10, wherein each of said mounting assemblies further includes a washer mounted on said bolt in spaced relation to said brace for confining said annulus axially therebetween.
