An agricultural work system comprising: a traction unit having a frame supported by a first front ground engaging element and a first rear ground engaging element, wherein the first front ground engaging element and the first rear ground engaging element are spaced apart from each other along a central longitudinal axis of the frame to define a wheelbase therebetween; a pitch sensor positioned to sense a pitch angle of the frame about a central transverse axis of the frame relative to a horizontal reference plane; a drawn mowing implement attached to a rearward end of the traction unit relative to a forward direction of travel of the traction unit, wherein the drawn implement includes a support structure having a ground clearance between the support structure and a ground surface; an adjustable component (70A, 70B) attached to at least one of the traction unit and the drawn implement, wherein the adjustable component (70A, 70B) is selectively controllable to adjust the ground clearance of the drawn implement; a controller in communication with the pitch sensor and the adjustable component (70A, 70B), the controller including a processor and a memory having a terrain tracking algorithm stored thereon, wherein the processor is operable to execute the terrain tracking algorithm to: receive a pitch signal from the pitch sensor indicating the pitch angle of the frame as the traction unit moves over a terrain feature in the ground surface; generate an elevation profile of the ground surface including the terrain feature from the pitch angle of the frame and the wheelbase of the traction unit; and control the adjustable component (70A, 70B) to adjust the ground clearance of the drawn mowing implement to maintain a minimum ground clearance between the support structure of the drawn mowing implement and the ground surface as the drawn mowing implement moves over the terrain feature in the ground surface to avoid contact between the support structure and a terrain feature in the ground surface as the drawn mowing implement moves over the terrain feature. a traction unit having a frame supported by a first front ground engaging element and a first rear ground engaging element, wherein the first front ground engaging element and the first rear ground engaging element are spaced apart from each other along a central longitudinal axis of the frame to define a wheelbase therebetween; a pitch sensor positioned to sense a pitch angle of the frame about a central transverse axis of the frame relative to a horizontal reference plane; a drawn mowing implement attached to a rearward end of the traction unit relative to a forward direction of travel of the traction unit, wherein the drawn implement includes a support structure having a ground clearance between the support structure and a ground surface; an adjustable component (70A, 70B) attached to at least one of the traction unit and the drawn implement, wherein the adjustable component (70A, 70B) is selectively controllable to adjust the ground clearance of the drawn implement; a controller in communication with the pitch sensor and the adjustable component (70A, 70B), the controller including a processor and a memory having a terrain tracking algorithm stored thereon, wherein the processor is operable to execute the terrain tracking algorithm to: receive a pitch signal from the pitch sensor indicating the pitch angle of the frame as the traction unit moves over a terrain feature in the ground surface; generate an elevation profile of the ground surface including the terrain feature from the pitch angle of the frame and the wheelbase of the traction unit; and control the adjustable component (70A, 70B) to adjust the ground clearance of the drawn mowing implement to maintain a minimum ground clearance between the support structure of the drawn mowing implement and the ground surface as the drawn mowing implement moves over the terrain feature in the ground surface to avoid contact between the support structure and a terrain feature in the ground surface as the drawn mowing implement moves over the terrain feature. receive a pitch signal from the pitch sensor indicating the pitch angle of the frame as the traction unit moves over a terrain feature in the ground surface; generate an elevation profile of the ground surface including the terrain feature from the pitch angle of the frame and the wheelbase of the traction unit; and control the adjustable component (70A, 70B) to adjust the ground clearance of the drawn mowing implement to maintain a minimum ground clearance between the support structure of the drawn mowing implement and the ground surface as the drawn mowing implement moves over the terrain feature in the ground surface to avoid contact between the support structure and a terrain feature in the ground surface as the drawn mowing implement moves over the terrain feature.
