Abstract
Abstract In a mower having a frame and a plurality of rotatable disks supported by the frame, a driving device is operable to rotate each disk, and includes a driving wheel associated with each disk, and a shaft in driven connection with a corresponding driving wheel. A coupling in driven connection with a corresponding shaft for coupling a corresponding disk to the corresponding shaft is provided, and an antifriction bearing guides the corresponding shaft. Each driving wheel and its corresponding shaft, coupling and anti-friction bearing constitutes a separately replaceable subassembly in the mower.

The mower as claimed in claim 1, wherein said antifriction bearing means are disposed between said coupling means and said driving wheel member in each subassembly.
Claim 4
Dependent Claim
85 words
The mower as claimed in claim 2, wherein said frame has a plurality of openings, and further comprising a plurality of covers covering said openings, respectively, and wherein each driving gear member has a diameter smaller than the largest width of a corresponding opening, so that the driving gear member of the corresponding subassembly can pass through the corresponding opening, a corresponding cover protecting the corresponding driving gear member, the external dimensions of the corresponding cover being greater than the size of a corresponding opening.
Claim 5
Dependent Claim
47 words
The mower as claimed in claim 1, wherein said disks are operatively disposed in a generally horizontal plane, and wherein the shaft member of each subassembly is operatively disposed below a corresponding disk, and a corresponding driving gear member is operatively disposed below the corresponding shaft member.
Claim 6
Dependent Claim
111 words
The mower as claimed in claims 1, 2, 3 or 4, wherein the coupling member of each subassembly comprises a sleeve member having a central bore, wherein the driving gear member thereof has a coaxial bore, and wherein at least one of the sleeve and driving gear members of said unit has an interior bore formed with teeth, said unit, being assembled by passing said shaft through said one of said sleeve and driving gear members, whereby the circumference of at least a portion of said shaft is deformed by said teeth of said bore so as to be firmly connected to said one of said sleeve and driving gear members.
Claim 7
Dependent Claim
119 words
In a mower having a frame and a plurality of subassemblies supported by said frame, each subassembly including a rotatable disk in combination at least one of said subassemblies forming a unit comprising driving means, including a driving gear member operable to rotate the disk of said unit, a shaft member in driven connection with said driving gear member, a coupling member in driven connection with said shaft member for coupling said disk to said shaft member, and bearing means for guiding said shaft member including antifriction means and a bearing block externally supporting said antifriction bearing means, said unit being removable from said mower free from damage to any of its members only if removed as a whole.
Claim 8
Dependent Claim
119 words
In a mower having a frame and a plurality of subassemblies supported by said frame, each subassembly including a rotatable disk in combination at least one of said subassemblies forming a unit comprising driving means, including a driving gear member operable to rotate the disk of said unit, a shaft member in driven connection with said driving gear member, a coupling member in driven connection with said shaft member for coupling said disk to said shaft member, and bearing means for guiding said shaft member including antifriction means and a bearing block externally supporting said antifriction bearing means, said unit being removable from said mower free from damage to any of its members only if removed as a whole.
Claim 9
Dependent Claim
23 words
The mower as claimed in claim 6, wherein said antifriction bearing means are disposed between said coupling member and said driving gear member.
Claim 10
Dependent Claim
85 words
The mower as claimed in claim 6, wherein said frame has a plurality of openings, and further comprising a plurality of covers covering said openings, respectively, and wherein each driving gear member has a diameter smaller than the largest width of a corresponding opening, so that the driving gear member of the corresponding subassembly can pass through the corresponding opening, a corresponding cover protecting the corresponding driving gear member, the external dimensions of the corresponding cover being greater than the size of a corresponding opening.
Claim 11
Dependent Claim
47 words
The mower as claimed in claim 6, wherein said disks are operatively disposed in a generally horizontal plane, and wherein the shaft member of each unit is operatively disposed below a corresponding disk, and a corresponding driving gear member is operatively disposed below the corresponding shaft member.
