The top portion is also configured so that at least part of the top portion is positioned above the cab of the work vehicle relative to a ground surface. In addition, a first height of a maximum vertical extent of the top portion relative to the ground surface is substantially equal to a second height of a maximum vertical extent of the rear portion relative to the ground surface. Further, the rear portion and the top portion are separated from one another while the rear portion is coupled to the chassis and the top portion is coupled to the cab. ## Claims ### Claim 1 A protection system for a work vehicle, comprising: a rear portion non-rotatably coupled to a chassis of the work vehicle; a top portion coupled to a cab of the work vehicle such that at least part of the top portion is positioned above the cab of the work vehicle relative to a ground surface, wherein a first height of a maximum vertical extent of the top portion relative to the ground surface is substantially equal to a second height of a maximum vertical extent of the rear portion relative to the ground surface. ### Claim 2 (depends on 1) The protection system of claim 1, wherein the rear portion is configured to be non-rotatably coupled to the chassis by at least one fastener. ### Claim 3 (depends on 1) The protection system of claim 1, wherein the rear portion remains non-rotatably coupled to the chassis while the cab of the work vehicle is rotated about a lateral axis. ### Claim 4 (depends on 1) The protection system of claim 1, wherein the rear portion is separated from the front portion by a gap extending along a lateral axis. ### Claim 5 (depends on 1) The protection system of claim 1, wherein the top portion comprises a light assembly coupled to a frame of the top portion. ### Claim 6 (depends on 1) The protection system of claim 1, wherein the top portion comprises a plurality of structural members, at least one of the plurality of structural members extends substantially along a longitudinal axis, and at least one of the plurality of structural members extends substantially along a lateral axis. ### Claim 7 (depends on 1) The protection system of claim 1, wherein rear portion comprises at least one substantially vertical structural member and at least one curved structural member extending from the at least one substantially vertical structural member. ### Claim 8 A protection system for a work vehicle, comprising: a rear portion configured to non-rotatably couple to a chassis of the work vehicle; a top portion configured to couple to a cab of the work vehicle such that at least part of the top portion is positioned above the cab of the work vehicle relative to a ground surface, and a first height of a maximum vertical extent of the top portion relative to the ground surface is substantially equal to a second height of a maximum vertical extent of the rear portion relative to the ground surface; and a coupling mechanism configured to selectively couple the rear portion to the top portion. ### Claim 9 (depends on 8) The protection system of claim 8, wherein the coupling mechanism comprises a plate and a pin or bolts. ### Claim 10 (depends on 8) The protection system of claim 8, wherein the coupling mechanism comprises a toolless fastener. ### Claim 11 (depends on 8) The protection system of claim 8, wherein the top portion comprises a light assembly coupled to a frame of the top portion. ### Claim 12 (depends on 8) The protection system of claim 8, wherein the top portion comprises a plurality of structural members, at least one of the plurality of structural members extends substantially along a longitudinal axis, and at least one of the plurality of structural members extends substantially along a lateral axis. ### Claim 13 (depends on 8) The protection system of claim 8, wherein rear portion comprises at least one substantially vertical structural member and at least one curved structural member extending from the at least one substantially vertical structural member. ### Claim 14 A work vehicle, comprising: a cab; a chassis; and a protection system comprising: a rear portion non-rotatably coupled to the chassis; and a top portion coupled to the cab such that at least part of the top portion is positioned above the cab relative to a ground surface, wherein a first height of a maximum vertical extent of the top portion relative to the ground surface is substantially equal to a second height of a maximum vertical extent of the rear portion relative to the ground surface. ### Claim 15 (depends on 14) The work vehicle of claim 14, wherein the rear portion is configured to be non-rotatably coupled to the chassis by at least one fastener. ### Claim 16 (depends on 14) The work vehicle of claim 14, wherein the rear portion remains non-rotatably coupled to the chassis while the cab is rotated about a lateral axis. ### Claim 17 (depends on 14) The work vehicle of claim 14, wherein the rear portion is separated from the front portion by a gap extending along a lateral axis. ### Claim 18 (depends on 14) The work vehicle of claim 14, wherein the top portion comprises a light assembly coupled to a frame of the top portion. ### Claim 19 (depends on 14) The work vehicle of claim 14, wherein the top portion comprises a plurality of structural members, at least one of the plurality of structural members extends substantially along a longitudinal axis, and at least one of the plurality of structural members extends substantially along a lateral axis. ### Claim 20 (depends on 14) The work vehicle of claim 14, wherein rear portion comprises at least one substantially vertical structural member and at least one curved structural member extending from the at least one substantially vertical structural member.
