DETAILED DESCRIPTION OF THE INVENTION

(6) FIG. 1 shows an exemplary embodiment of the invention in the form of an agricultural applicator 10 having a chassis 12 including a bed 14 (see FIG. 2) that is adapted for removable mounting on the bed 14 of an agricultural product sprayer 16 having left and right foldable booms 18,20. The agricultural product sprayer 16 includes a skid 22, according to the invention, that is adapted for operative removable connection to the applicator chassis 12. The rear end 24 (see FIG. 3) of the skid 22 is adapted for operative attachment to the skid 22 of the left and right foldable booms 18,20.

(7) As shown in FIGS. 2 and 3, the skid 22 includes left and right boom cradles 26,28 that are adapted for supporting the left and right foldable booms 18,20 in their folded positions when the skid 22 is mounted on the chassis 12, and also when the skid 22 is separated from the chassis 22 of the agricultural applicator 10.

(8) As shown in FIG. 3, the skid 22 defines a longitudinal axis 30 of the skid 22 and a first end 24 of the skid 22 disposed along the longitudinal axis 30 of the skid 22. The first end 24 is adapted for operative attachment of proximal, first ends of the foldable booms 18,20. The boom cradles 26,28 are located at an opposite longitudinal end 32 of the skid 22, and are adapted for receiving and supporting the distal ends of the folded booms 26,28.

(9) In the exemplary embodiment of the applicator 10 and sprayer 16, the first end 24 of the skid 22 is the rear end 24 of the skid 22, and the opposite end 32 of the skid 22 is the front end 32 of the skid 22 when the sprayer 16 is mounted on the chassis 12 of the applicator 10. It will be understood, however, that in other embodiments of the invention the proximal ends of the booms 16,28 may be mounted to the front of the skid 22, and the boom cradles be positioned at a rear end of the skid 22.

(10) It will also be appreciated that, in the exemplary embodiment of the applicator 10 and sprayer 16, the skid 22 and its attached boom cradles 26,28 are adapted for respectively supporting the left and right foldable booms 18,20 in their folded positions when the skid 22 is mounted on the chassis 12. In addition, because the boom cradles 26,28 are part of the skid 22, they also provide support for the folded booms 18,20 while the sprayer 16 is being lifted off of, or on to the chassis 12 of the applicator 10, as shown in FIG. 2, and also when the sprayer 16 is separated from the chassis 12 of the agricultural applicator 10.

(11) As shown in FIG. 3, the boom cradles 26,28 each include a boom latch, or lock 27,29 for securing the folded booms 18,20 in the cradles 26,28. In various forms of the invention, these latches or locks 27,29 may be configured and actuated in any appropriate manner, such as manually or mechanically, remotely or at the boom cradles 26,28.

(12) As shown in FIGS. 2 and 3, the exemplary embodiment of skid 22 includes lifting arrangement attachment elements, in the form of four lifting eyes 34,36,38,40 that are adapted for attachment of a lifting arrangement 44 for mounting the sprayer 16 on, and removing the sprayer 16 from the chassis 12. The invention may also be practiced with any other appropriate lifting provisions.
