Feed roller mechanisms for forage harvesters
 The invention comprises a feed roller mechanism for use with forage harvesters adapted for picking up cut forage material from the ground and thereafter moving said forage material up a conveyor to a feed roller mechanism which grips and compresses the forage materials sufficiently for it to be passed to a cutter whereafter the forage material may be cut into small pieces and moved to a storage container for transportation and/or processing. The apparatus provides a feed roller mechanism having a roller or rollers biased by an adjustable thruster towards an upper end of a conveyor and able to move substantially vertically relative thereto, said feed roller mechanism being prevented from tilting or rocking relative to the conveyor by a tie-bar to cause the feed roller or rollers to exert increased pressure on any forage material building up to one side of the conveyor, adjusting means provided on the thruster to enable the feed roller mechanism to be capable of being raised clear of the conveyor for removal of clogged or foreign material and also to enable the bias of the feed roller mechanism towards the conveyor to be substantially adjustable to suit the type of forage material being harvested.
