Adjustable attachment for mounting a farming tool on a drawing vehicle

A distribution tube for distributing an additive from an additive supply to soil, the distribution tube being attachable to a distribution implement having a vertical shank having a transverse leg for passing through a particulate matter at one end and means for attaching the vertical shank to a tool bar attached to a drawing vehicle such as a tractor at the other end, the vertical shank and the transverse leg having a leading and a trailing edge, with a means for attaching the distribution tube associated with the trailing edge, the distribution tube comprising:

• a tubular body made of plastic having an inlet portion and an outlet portion at an angle to each other and divided by a preformed bend, the angle between the inlet portion and the outlet portion being less than 90.degree., the inlet portion having a plurality of integrally formed annular barbs for preventing separation from the inlet portion of a supply conduit attached to the inlet portion, the supply conduit being in fluid communication with the additive supply, the tubular body conforming to the trailing edge of the shank and the transverse member such that the shank and the transverse member protect the tubular body from abrasion once the distribution tube is attached to the trailing edge of the shank and the transverse member by a means for attaching and the shank and the transverse member passes through a particulate matter, the outlet portion being proximate an end of the transverse member away from the shank.
