Planter with retractable access
View Patent ↗A towed implement, such as a planter is provided with a folding platform allowing easy access to upper regions of the implement. The platform may be provided in addition to a transverse platform or other upper walkway, such as for access to seed tanks in planters. The folding platform may be deployed, along with handrails and a ladder for accessing the platform for servicing the implement. When not in use, the folding platform may be collapsed or folded, and other ancillary structures, such as the ladder may be moved to stowed positions.
1. A towed agricultural implement comprising:
a frame including a tool bar extending generally transverse to a central axis along which the implement is towed in operation;
a plurality of ground-contacting units coupled to the frame and disposed generally beneath the tool bar; and
a folding operator platform supported on the frame and disposed generally fore-and-aft above the ground-contacting units, wherein the folding platform includes a pair of folding panels; and
a retractable ladder extending from the folding platform aft behind the ground-contacting units.
2. The implement of claim 1 , wherein the panels fold along a line generally parallel to the central axis.
3. The implement of claim 1 , comprising at least one tank supported generally above the tool bar and a fixed operator platform extending generally transverse to the central axis aft of the tank.
4. The implement of claim 3 , wherein the folding platform is disposed aft of the fixed platform.
5. The implement of claim 4 , wherein a forward edge of the folding platform is disposed substantially at a level of the fixed platform when the folding platform is unfolded.
6. The implement of claim 1 , wherein the ladder is displaceable into a space below the folding platform when the platform is folded.
7. The implement of claim 1 , comprising a pair of hand rails disposed on lateral sides of the folding platform.
8. The implement of claim 7 , wherein the hand rails are moveable inwardly towards one another when the platform is folded.
9. The implement of claim 1 , wherein the retractable ladder is extendable from and retractable into a ladder storage receptacle, and the folding panels are foldable and unfoldable directly above the ladder storage receptacle.
10. A towed agricultural implement comprising:
a frame including a tool bar extending generally transverse to a central axis along which the implement is towed in operation;
at least one seed tank supported by the frame and generally above the tool bar;
a seed distribution system for distributing seeds from the tank;
a plurality of row units coupled to the frame and disposed generally beneath the tool bar, the row units receiving seeds from the distribution system during operation; and
a plurality of row units coupled to the frame and disposed generally beneath the tool bar;
a fixed operator platform extending generally transverse to the central axis aft of the tank;
a folding operator platform supported on the frame and disposed generally fore-and-aft above the row units and aft of the fixed platform, wherein the folding operator platform includes a pair of folding panels; and
a retractable ladder extending from the folding platform aft behind the row units.
11. The implement of claim 10 , wherein the panels fold along a line generally parallel to the central axis.
12. The implement of claim 10 , wherein a forward edge of the folding platform is disposed substantially at a level of the fixed platform when the folding platform is unfolded.
13. The implement of claim 10 , wherein the ladder is displaceable into a space below the folding platform when the platform is folded.
14. The implement of claim 10 , comprising a pair of hand rails disposed on lateral sides of the folding platform.
15. The implement of claim 14 , wherein the hand rails are moveable inwardly towards one another when the platform is folded.
16. The implement of claim 10 , wherein the retractable ladder is extendable from and retractable into a ladder storage receptacle, and the folding panels are foldable and unfoldable directly above the ladder storage receptacle.
17. A towed agricultural implement comprising:
a frame including a tool bar extending generally transverse to a central axis along which the implement is towed in operation;
a plurality of seed tanks supported by the frame and generally above the tool bar;
a seed distribution system for distributing seeds from the tanks;
a plurality of row units coupled to the frame and disposed generally beneath the tool bar, the row units receiving seeds from the distribution system during operation; and
a plurality of row units coupled to the frame and disposed generally beneath the tool bar;
a fixed operator platform extending generally transverse to the central axis aft of the tanks;
a folding operator platform supported on the frame and disposed generally fore-and-aft above the row units and aft of the fixed platform, the folding platform being foldable along a line generally parallel to the central axis;
a pair of hand rails disposed on lateral sides of the folding platform and movable inwardly towards one another when the platform is folded; and
a retractable ladder extending from the folding platform aft behind the row units.
18. The implement of claim 17 , wherein the folding platform includes a pair of folding panels.
19. The implement of claim 17 , wherein a forward edge of the folding platform is disposed substantially at a level of the fixed platform when the folding platform is unfolded.
20. The implement of claim 17 , wherein the ladder is displaceable into a space below the folding platform when the platform is folded.
