## Abstract

A lawn care device (10) may include an articulated frame (40), a cutting deck (50, 100), a collection container (12) and a chute (82). The articulated frame (40) may include a front frame portion (42) to which front wheels (34) are operably coupled and a rear frame portion (44) to which rear wheels (32) are operably coupled, the front frame portion (42) and rear frame portions (44) being operably coupled by an articulated joint. The cutting deck (100) may house at least one blade (110, 112, 114) and the cutting deck (100) may be mounted to the front frame portion (42), forward of the front wheels (34). The collection container (12) may collect material from the cutting deck (50, 100) and may be affixed to the front frame portion (42) and suspended over the rear wheels (32). The chute (82) may be operably coupling the cutting deck (50, 100) and the collection container (12) to pass the material from the cutting deck (50, 100) to the collection container (12).

## Claims

### Claim 1

A lawn care device comprising:
an articulated frame comprising a front frame portion to which front wheels are operably coupled and a rear frame portion to which rear wheels are operably coupled, the front and rear frame portions being operably coupled by an articulated joint;
a cutting deck housing at least one blade, the cutting deck being mounted forward of the front wheels to the front frame portion;
a motor selectively engaged with the cutting deck;
a collection container for collecting material from the cutting deck, the collection container and the motor being affixed to the front frame portion and suspended over the rear frame portion, wherein the rear frame portion is rotatable about the articulated joint without corresponding rotation of the collection container and the motor; and
a chute operably coupling the cutting deck and the collection container to pass the material from the cutting deck to the collection container.

### Claim 2 (depends on 1)

The lawn care device of claim 1, wherein the chute extends substantially in a straight line between the cutting deck and the collection container.

### Claim 3 (depends on 2)

The lawn care device of claim 2, wherein the chute rises in elevation from the cutting deck to the collection container.

### Claim 4 (depends on 1)

The lawn care device of claim 1, wherein the collection container is disposed proximate to the motor of the lawn care device, the motor and the collection container remaining fixed relative to the front frame portion when the rear frame portion rotates about the articulated joint.

### Claim 5 (depends on 4)

The lawn care device of claim 4, wherein the motor powers the rear wheels.

### Claim 6 (depends on 1)

The lawn care device of claim 1, further comprising an auger assembly associated with the chute to convey the material between the cutting deck and the collection container.

### Claim 7 (depends on 6)

The lawn care device of claim 6, wherein the auger assembly comprises an auger comprising a helical blade that is disposed within the chute, the auger transporting the material from a pickup point at a first end of the chute to an emptying point within the collection container at an opposite end of the chute.

### Claim 8 (depends on 7)

The lawn care device of claim 7, wherein the pickup point is disposed at a longitudinal centerline of the lawn care device and the chute extends along the longitudinal centerline of the lawn care device.

### Claim 9 (depends on 8)

The lawn care device of claim 8, wherein the cutting deck houses a first blade and a second blade that rotate in opposing directions relative to each other, and wherein the pickup point is disposed at a point radially equidistant from an axis of rotation of the first and second blades.

### Claim 10 (depends on 9)

The lawn care device of claim 9, wherein the pickup point is disposed proximate to a forward portion of the cutting deck.

### Claim 11 (depends on 9)

The lawn care device of claim 9, wherein the pickup point is disposed proximate to a rear portion of the cutting deck.

### Claim 12 (depends on 7)

The lawn care device of claim 7, wherein the pickup point is disposed spaced apart from a longitudinal centerline of the lawn care device and the chute extends parallel to and spaced apart from the longitudinal centerline of the lawn care device.

### Claim 13 (depends on 7)

The lawn care device of claim 7, wherein the auger passively receives the material at the pickup point responsive to operation of the at least one blade.

### Claim 14 (depends on 7)

The lawn care device of claim 7, wherein the auger receives the material at the pickup point responsive to active feeding of the material into the pickup point.

### Claim 15 (depends on 7)

The lawn care device of claim 7, wherein the auger receives the material at the pickup point responsive to active feeding of the material into the pickup point via a feed auger operably coupling the material from the cutting deck to the pickup point.

### Claim 16 (depends on 15)

The lawn care device of claim 15, wherein the auger receives the material at the pickup point responsive to active feeding of the material into the pickup point, and wherein the feed auger extends in a direction substantially perpendicular to the direction of extension of the chute.

### Claim 17 (depends on 1)

The lawn care device of claim 1, further comprising a belt conveyor assembly associated with the chute to convey the material between the cutting deck and the collection container.

### Claim 18 (depends on 17)

The lawn care device of claim 17, wherein the belt conveyor assembly comprises a belt disposed in a bottom portion of the chute.

### Claim 19 (depends on 1)

The lawn care device of claim 1, wherein the chute is not flexible and does not rotate responsive to rotation of the rear frame about the articulated joint.

### Claim 20

A transport mechanism for operably coupling a cutting deck of a lawn care device to a collection container for collecting material responsive to operation of the cutting deck, the transport mechanism comprising:
a chute operably coupling the cutting deck and the collection container to pass the material from the cutting deck to the collection container; and
an auger assembly disposed within the chute to convey the material between the cutting deck and the collection container,
wherein the lawn care device comprises:
a motor; and
an articulated frame comprising a front frame portion to which front wheels are operably coupled and a rear frame portion to which rear wheels are operably coupled, the front and rear frame portions being operably coupled by an articulated joint, and
wherein the collection container and the motor are affixed to the front frame portion and suspended over the rear frame portion such that the rear frame portion is rotatable about the articulated joint without corresponding rotation of the collection container and the motor.
