A crawler belt for use on a crawler motor vehicle has an elongate belt body drivable in a predetermined direction, and a plurality of ridges mounted on a ground contact side of the belt body, each of the ridges having at least one sipe defined in a free end thereof for allowing the ridge to be flexibly deformable in a direction opposite to the predetermined direction. Each of the ridges has a plurality of sipes defined therein and extending longitudinally thereof or substantially perpendicularly to the predetermined direction. The ridges comprise a plurality of chevron-shaped ridges pointing toward the predetermined direction and succesively arranged at predetermined spaced intervals in the predetermined direction. The ridges are divided into a plurality of groups each including a plurality of ridges by grooves extending transversely of the belt body, and divided into a plurality of segments by at least one longitudinal groove extending longitudinally of the belt body.

A crawler belt comprising (a) an elongate endless belt body extending longitudinally and having a first side for ground contact and a second side opposite said first side, said belt body being drivable longitudinally in a first direction; and (b) a plurality of ridges on said first side extending outward therefrom, each of said ridges comprising a plurality of sipes defined therein and extending longitudinally thereof for allowing said ridge to be flexibly deformable in a second direction opposite said first direction; said ridges formed into groups respectively defining a plurality of at least partial chevron-shapes all pointing in said first direction, said groups successively arranged at predetermined spaced intervals in said first direction, said groups being separated from each other by grooves extending transversely and generally perpendicular of said longitudinal extent of said belt body; and each of said groups is divided into a plurality of sub-groups by at least two transversely spaced grooves extending longitudinally of said belt body, thus forming a left side subgroup, a right side subgroup and central segments disposed between said left and right side subgroups, and wherein each left and right side subgroup comprises at least one first end segment having a generally rectangular cross-section and at least one second end segment having a convex arcuate edge outward of said belt body.
