A vehicle for placing irrigation pipe, and a method for placing irrigation pipe, is described. The vehicle has a tricycle configuration, with in-line a front steerable drive wheel, a rear drive wheel and a pipe clamp, and an adjustable side idler wheel that provides stability. As the vehicle moves though a field, pulling ever increasing length of pipe, the force provided by the drive wheels increases in proportion.

The use of an accumulator attached to a chamber of a cylinder allows for the reduction in pressure spikes in constant force hydraulic control systems. Constant force hydraulic control systems often use a differential pressure valve that may have a reaction time of up to one second. By using the accumulator, pressure spikes which might have occurred in the past can be smoothed out and reduced, thus preventing damage to a workpiece or agricultural product. Additionally, by using two cylinders of different sizes, in which one of the cylinders has a barrel end with the approximately the same area as the rod end of the larger cylinder, coordination of devices attached to the cylinders can be maintained without a mechanical link when the hydraulic control system is in a manual mode.
