Abstract
In a self-propelled, hydraulic four wheel drivetwo row cane harvester having a four-row piler with a main power source driving variable volume pumps for propulsion and operation; structural and operational improvements of a shortened wheel base, outward extension of right rear center carrier, individual suspension of rear wheels for stability on uneven ground, steerable rear wheels differentially linked by means of bell crank linkages, single articulation pilers having multiple row piling capacity, adjustable cane butt deflectors, and a combination range and speed controls with independent adjustments of ranges ground chain speeds and unit control of the cut cane carrier chains of all speeds within the set range.
Claims6
In a four-wheel harvester and pilers, having a right rear carrier frame member, sequential pairs of cane-moving chains, and a power train with hydraulic means for driving said chains and wheels and pilers,
- (a) individual suspension means for independently mounting rear wheels on said harvester and pilers to provide harvester and pilers mobile stability on uneven ground
- (b) individual speed range setting means and unitary mechanical speed control means respectively connected to said hydraulic means for driving said chains and wheels for individually setting speed ranges and controlling the speed within any of said ranges of said chains and wheels,
- (c) single articulation piler means mounted behind and above said four wheels on said harvester and pilers and operably connected to said hydraulic means, and having longitudinally adjustable rub bar gate means fixed thereto for cooperating in side piling two rows of cut cane and center piling two rows,
- (d) cane butt deflector means mounted on said harvester and pilers and pivotally adjustable to extend below and across said adjustable rub bar gate means for cooperating with said piler means in center piling two rows, and
- (e) outward extension means fixed to said carrier frame member just forward of right rear wheel for providing additional fall space for center piled cane.
