The Articulator 621EF deck tackles the rough with three 42-inch decks, cutting 126 inches at a time. The hydraulic lift raises the two outside decks easily so it will go anywhere your tractor can take it. The 621EF delivers where ground-hugging cut quality is important, but perhaps not as extreme as those requiring the 21" decks of the 721XR.

621EF Out Front Mower

The Articulator 621EF features a 10'-6" bat wing front mount deck that utilizes 3 independent 42" decks. The 621EF can achieve 24 degrees of motion along the contour of the ground. Because of its ability to contour, the 621EF can cut in valleys or over hills where flat mowers simply cannot.
