ABSTRACT:
A five section implement uses a pair of folding mechanisms to fold primary and secondary wing sections above a central main section. The folding mechanisms are disposed mainly on the top side of the primary wing sections thereby providing adequate space on the top of the main section for mounting containers for dispensing liquid agricultural chemicals. Each folding mechanism includes a lost motion connection permitting floating of the implement sections, automatic lock-out structure for the lost motion connection which operates during fold-up of the implement and an automatic gravity operated latch which insures a proper sequence of unfolding of the wing sections. Each folding mechanism is operated by a single hydraulic actuator and a transport locking bar disposed alongside each actuator is provided with a slide pad to prevent damage to the actuator and other parts during operation of the associated folding mechanism.
