Abstract
Abstract A tractor drawn and powered agricultural machine, such as a mower-conditioner for hay-like crops, comprises a main frame having a pair of spaced apart side walls between which a sickle mower, a tine reel, a pair of conditioning rolls, a crop gathering hood and windrowing means, and a pair of transport wheel assemblies are mounted. Operating power from the tractor is supplied through a rotatable power take-off shaft and clutches to a transmission unit comprising enclosed gears which is mounted on the main frame outboard of one side wall. The transmission unit is connected to and drives the conditioning rolls by means of universal drive shafts and the upper roll is spring mounted so as to be relatively movable and self-adjusting with respect to the lower roll. The transmission unit is also connected to and drives the sickle mower through a reciprocating pitman drive which includes a break-away bolt which breaks if the sickle-bar jams. The time reel, which is adjustably mounted on the side walls, is chain driven from the upper conditioning roll and tine pitch is adjustable by adjustable cam means.
