Abstract
An automatic terrain adjustment system automatically adjusts the forward and rearward height of a tractor-towed agricultural implement, such as a defoliator, responsive to a sensed change in the depth of terrain over which the agricultural implement traverses. The forward height of the implement is adjusted independently of the rearward height of the implement using two distinct automatic depth controlling systems. Each automatic depth controlling system utilizes a linkage in conjunction with a sensing wheel and hydraulic valve to control either a rear actuator, which adjusts a height of a rear axle of the implement, or a forward actuator, which adjusts a height of the front of the implement.
Claims20
An automatic terrain adjustment system for an agricultural implement comprising:
- (a) a right automatic depth controlling system including:
- a right linkage that couples a right sensing wheel with a right valve, the right linkage secured to a forward member of the agricultural implement proximate a right side of the agricultural implement;
- and
- a right hydraulic actuator fluidly coupled to the right valve, the right hydraulic actuator connected between a rear member of the agricultural implement and a height-adjustable axle connected between two wheels that support the right side of the agricultural implement at a rear of the agricultural implement,
- wherein movement of the right linkage enables the right sensing wheel to sense a right depth of terrain as the right sensing wheel traverses the terrain while the agricultural implement is pulled by a tractor, and
- wherein, responsive to the right depth of terrain, the right valve supplies hydraulic fluid to the right hydraulic actuator to position the height-adjustable axle to a height corresponding to the right depth of terrain, and
- (b) a left automatic depth controlling system including:
- a left linkage that couples a left sensing wheel with a left valve, the left linkage secured to the forward member of the agricultural implement proximate a left side of the agricultural implement;
- and
- a left hydraulic actuator fluidly coupled to the left valve, the left hydraulic actuator connected between the front member of the agricultural implement and a tongue of the agricultural implement,
- wherein movement of the left linkage enables the left sensing wheel to sense a left depth of terrain as the left sensing wheel traverses the terrain while the agricultural implement is pulled behind the tractor, and
- wherein, responsive to the left depth of terrain, the left valve supplies hydraulic fluid to the left hydraulic actuator to position a front of the agricultural implement to a height corresponding to the left depth of terrain.

An automatic terrain adjustment system for an agricultural implement comprising:
- (a) a right automatic depth controlling system including:
- a right four-member linkage coupled to a right sensing wheel and directly interfaced to a right hydraulic valve, the right linkage secured to a forward member of the agricultural implement proximate a right side of the agricultural implement;
- and
- a right hydraulic actuator fluidly coupled to the right hydraulic valve, the right hydraulic actuator connected between a rear member of the agricultural implement and a height-adjustable axle connected between two wheels that support the right side of the agricultural implement at a rear of the agricultural implement,
- wherein movement of the right linkage enables the right sensing wheel to sense a right depth of terrain as the right sensing wheel traverses the terrain while the agricultural implement is pulled by a tractor, and
- wherein, responsive to the right depth of terrain, the right four-member linkage operates the right hydraulic valve to supply or withhold hydraulic fluid to the right hydraulic actuator to position the height-adjustable axle to a height corresponding to the right depth of terrain;
- and
- (b) a left automatic depth controlling system including:
- a left four-member linkage coupled to a left sensing wheel and directly interfaced to a left hydraulic valve, the left linkage secured to the forward member of the agricultural implement proximate a left side of the agricultural implement;
- and
- a left hydraulic actuator fluidly coupled to the left hydraulic valve, the left hydraulic actuator connected between the front member of the agricultural implement and a tongue of the agricultural implement,
- wherein movement of the left linkage enables the left sensing wheel to sense a left depth of terrain as the left sensing wheel traverses the terrain while the agricultural implement is pulled behind the tractor, and
- wherein, responsive to the left depth of terrain, the left four-member linkage operates the left hydraulic valve to supply or withhold hydraulic fluid to the left hydraulic actuator to position a front of the agricultural implement to a height corresponding to the left depth of terrain.
