Claim 3

Dependent Claim 9 words

(e) first powered means for selectively rotating the table;

Claim 4

Dependent Claim 9 words

(e) first powered means for selectively rotating the table;

Claim 5

Dependent Claim 98 words

(f) bale wrap mounting means carried by the machine and disposed adjacent the table for supporting a cylindrical roll of sheet material for rotation about a generally vertical axis; (g) bale handling means carried by the machine for engaging a bale lying on its peripheral side on the ground and disposing one end of the same on the bale wrapping table for rotation therewith, the bale handling means after wrapping of the bale thereupon redisposing the wrapped bale back onto the ground on its peripheral side; and (h) second powered means for selectively operating the bale handling means.

Claim 6

Dependent Claim 98 words

(f) bale wrap mounting means carried by the machine and disposed adjacent the table for supporting a cylindrical roll of sheet material for rotation about a generally vertical axis; (g) bale handling means carried by the machine for engaging a bale lying on its peripheral side on the ground and disposing one end of the same on the bale wrapping table for rotation therewith, the bale handling means after wrapping of the bale thereupon redisposing the wrapped bale back onto the ground on its peripheral side; and (h) second powered means for selectively operating the bale handling means.

Claim 7

Dependent Claim 15 words

The machine of claim 1 wherein the transport means includes means for towing the machine.

Claim 8

Dependent Claim 22 words

The machine of claim 2 wherein the powered means include means disposed for operative attachment to power means external of the machine.

Claim 9

Dependent Claim 82 words

The machine of claim 1 wherein the bale handling means is disposed adjacent the rearward end of the machine and is movable between lower and upper positions, the bale handling means when in its lower position being effective to engage a bale lying on the ground on its peripheral side upon rearward movement of the machine, the bale handling means when moved to its upper position being effective to elevate the bale and dispose one end of same on the wrapping table.

Claim 10

Dependent Claim 104 words

The machine of claim 4 wherein the bale handling means includes scoop means having opposite ends, one end being pivoted about a transverse axis at the rearward end of the frame, the other end of the scoop means being effective when in a lower position adjacent the ground to engage the under peripheral side of a bale on the ground upon rearward movement of the machine, the second powered means being effective to move the scoop means about said pivot between its lower position and an upper substantially vertical position adjacent the bale wrapping table effective to deposit one end of the bale thereon.

Claim 11

Dependent Claim 21 words

The machine of claim 5 wherein the scoop means comprise laterally spaced arms, the second powered means including a hydraulic ram.

Claim 12

Dependent Claim 61 words

The machine of claim 5 wherein the bale handling means also includes bale unloading means for moving a bale on the wrapping table after its wrapping into engagement with the scoop means and to lower the bale to the ground when the scoop means is moved to its lower position, and third powered means for selectively operating the bale unloading means.

Claim 13

Dependent Claim 98 words

The machine of claim 7 wherein the bale unloading means includes bale tilting means disposed adjacent the bale wrapping table substantially diametrically opposite the scoop means, the bale tilting means being effective to engage the peripheral side of a bale disposed on the bale wrapping table, actuation of the third powered means being effective to tilt the bale onto the scoop means, actuation of the second powered means being effective to move the scoop means with the bale thereon to its lower position, forward movement of the machine being effective to disengage the scoop means from the bale.

Claim 14

Dependent Claim 47 words

The machine of claim 8 wherein the bale tilting means includes an arm pivoted at one end relative to the frame, the other end of the arm having roller means thereon engageable with the peripheral side of a bale, the third powered means including a hydraulic ram.

Claim 15

Independent Claim 122 words

A method of wrapping a large cylindrical hay bale disposed upon the ground, the bale having a pair of opposite ends and a cylindrical peripheral surface therebetween having an axis, the method comprising: (a) lifting the bale from the ground; (b) positioning the lifted bale so that said axis is substantially vertical; (c) fixing one transverse end of a length of sheet material relative to the bale so that said material end extends substantially across said bale surface between said bale ends; (d) rotating the bale about said axis while feeding the sheet material onto said bale surface so that the same is wrapped around with the sheet material; and (e) securing a second end of the sheet material to the bale.

Claim 16

Independent Claim 122 words

A method of wrapping a large cylindrical hay bale disposed upon the ground, the bale having a pair of opposite ends and a cylindrical peripheral surface therebetween having an axis, the method comprising: (a) lifting the bale from the ground; (b) positioning the lifted bale so that said axis is substantially vertical; (c) fixing one transverse end of a length of sheet material relative to the bale so that said material end extends substantially across said bale surface between said bale ends; (d) rotating the bale about said axis while feeding the sheet material onto said bale surface so that the same is wrapped around with the sheet material; and (e) securing a second end of the sheet material to the bale.

Claim 17

Dependent Claim 57 words

The method of claim 10 wherein the sheet material is fed from a cylindrical roll thereof having an axis disposed substantially vertically, the roll being positioned alongside the bale during said rotation thereof, and including detaching the sheet material from the roll after said wrapping thereof in order to provide said second end of the sheet material.

Claim 18

Dependent Claim 30 words

The method of claim 11 wherein the bale, after securing said second end of the sheet material as aforesaid, is returned to the ground disposed upon its wrapped peripheral surface.
