High-clearance sprayers are getting larger and more complex to allow for increasing coverage in a single pass, which improves application efficiency. These high-clearance sprayers have complex product delivery and rinse systems along with other engine driven accessories and systems that need inspection and servicing. Decks are provided on the sprayer that provide walkways from rear-mounted ladders to the cab and also to provide platforms for operators to stand on while inspecting and servicing the various systems of the sprayers. Additionally, railings are arranged as outer barriers for the decks. Previously, deck railings were used that included a front railing that extends from a boom rest forward along the length of a side deck and a back railing arranged behind the boom rest at the side deck. Traditionally, the back railing had a hoop-like configuration with an end of a forward post connected to the platform and an end of a rearward post connected to a ladder bracket. A rearward end of the front railing was also attached to a movable boom rest that can be moved closer to a product tank as a transport position that provides a narrower width of the sprayer. The forward end of the front railing was also movably attached to the deck by way of a complicated railing slid mechanism with a sliding bracket that received an end of a tube of the front railing. Additionally, a pair of plastic slide washers fit on a pair of posts that were slidable within a slot in the deck. This allowed the forward end of the front railing to move inwardly toward the product tank as a transport position. Such a slidable version required fabrication of the sliding bracket and additional assembly time.
