Abstract
An agricultural implement is disclosed for raking and tedding a swath of hay into a tedded windrow with a single pass of the implement along the swath of hay. The implement includes a plurality of circular rake wheels and a rotatable tedder, both mounted on a common base frame. First and second height adjustment mechanisms are included for the selective, independent adjustment of the height of the tedder and the height of the rake wheels. A lateral adjustment mechanism is provided for selectively adjusting the lateral relationship of the implement with respect to a towing vehicle.
Claims23
An agricultural implement adapted for being towed by a tractor or the like along a path of travel relative to a swath of hay or the like. comprising:
- a base frame adapted for towing behind said tractor or the like;
- a pair of opposed, ground engaging wheels aligned along a base frame support axis operably supporting said base frame about said axis for movement of said base frame along said path of travel;
- rake means operably coupled to said base frame for forming said swath of hay into a windrow;
- tedding means operably coupled to said base frame rearwardly of said rake means for tedding said windrow;
- tow means adapted for operably, detachably coupling said base frame to said tractor or the like, said tow means including means for laterally shifting said base frame relative to said tractor or the like;
- first height adjustment means operably coupling said tow means and said base frame for selectively pivoting said base frame about said base frame axis, thereby selectively adjusting the height of said tedding means relative to the ground;
- and
- second height adjustment means operably coupling said rake means and said base frame for adjusting the height of said rake means independently of the height of said tedding means.
An agricultural implement adapted for passing along a path of travel relative to a swath of hay or the like, comprising:
- a base frame;
- ground engaging wheels operably supporting said base frame for movement of said base frame along said path of travel;
- rake means operably coupled to said base frame for forming said swath of hay into a windrow, said rake means including a rake element and a rake support arm operably, pivotally coupling said rake element to said base frame about a rake support arm pivot point;
- tedding means operably coupled to said base frame rearwardly of said rake means for tedding said windrow, whereby said swath of hay or the like is formed into a windrow, and said windrow is tedded, in a single pass of said implement along said path of travel;
- first height adjustment means operably coupled to said base frame for selective adjustment of the height of said tedding means;
- and
- second height adjustment means operably coupled to said base frame for selective adjustment of the height of said rake means independently of the height of said tedding means,
- said second height adjustment means comprising means for pivoting said rake support arm about said rake support arm pivot point, said second height adjustment means further comprising a selectively extensible second height adjustment elongated member having first and second opposed ends, said first end of said second height adjustment elongated member being operably, pivotally coupled to said base frame, and the second end of said second height adjustment elongated member being operably, pivotally coupled to said rake support arm at a point spaced apart from said rake support arm pivot point, and means for selectively adjusting the length of said second height adjustment elongated member.
