Abstract
A hay-making machine having a plurality of rotary rakes thereon which are rotatably driven about generally vertical axes or rotation. The hay-making machine is supported by a plurality of wheels to facilitate its movement relative to the ground. The hay-making machine is connected by a hitch mechanism to a tractor and the rotary rakes are driven by a shaft connection to the power take-off equipment on the tractor. The hay-making machine is comprised of a main frame and auxiliary frames. The main frame is pivotally secured to the hitch and the auxiliary frame is connected pivotally to the main frame to compensate for variations in ground irregularities. Telescoping shafts are utilized on the machine to facilitate a change in length between the rotary rake members and the hitch as the hay-making machine moves relative to the ground.
Claims21
A hay-making machine having several rotary rakes which are driven rotatingly about approximately vertical axes of rotation and are supported on the ground by means of wheels, comprising:
- a machine frame having a tongue, a main frame and auxiliary frames, said main frame being arranged hingedly on said tongue;
- at least an inner and an outer rotary rake mounted on each auxiliary frame to form one group, each inner and outer rotary rake having an input shaft for effecting a drive thereof and adjusting means for fixing said auxiliary frames to said main frame in various adjusted positions;
- a main gearing mounted on said tongue and having two lateral output shafts;
- a telescopingly elongatable drive shaft connecting each of said lateral output shafts to said input shaft to said outer rotary rake in each group and a longitudinally variable drive shaft for connecting the drive to said outer rotary rake to said input shaft to said inner rotary rake;
- and
- means for effecting an inclination adjustment of said main frame with respect to said tongue.
