ABSTRACT:
A wheeled trailer, such as a liquid manure spreader, has a draft tongue which is adapted for attachment to a draft connection of a farm tractor so as to trail behind a soil working implement, such as a liquid manure injector, which is mounted upon the tractor three point hitch; and a driven member, such as a fertilizer pump, is driven from the tractor power take-off which is in a horizontal plane above that of the draft connection. The length of the draft tongue is sufficient to avoid interference between the implement and the vehicle on turns. The power train for the driven member consists of a drive shaft connected to the driven member which is in a horizontal plane below that of the p.t.o., an input shaft on the forward part of the tongue which is in the plane of the p.t.o. and is detachably connected to the p.t.o. by a drive link, and a driving connection between the input shaft and the drive shaft. A hood both mounts and covers the input shaft and the driving connection, and a shield covers the forward part of the drive shaft.
