A crawler track includes a link and is driven in a direction of travel by a sprocket having a plurality of teeth. The link includes a pad, a first grouser, and a second grouser. The pad defines a first surface, a second surface opposite the first surface, a first end, and a second end spaced apart from the first end along the direction of travel. The pad defines at least one opening extending through the pad between the first surface and the second surface, and the opening is operable to receive a sprocket tooth. The first grouser is positioned on the first surface proximate the first end of the pad, while the second grouser is positioned on the first surface proximate the second end of the pad. The first grouser and the second grouser extend in a direction substantially perpendicular to the direction of travel of the track.

The track of claim 1, wherein at least one of the first lugs of the first link is aligned with at least one of second lugs of the second link, the at least one first lug of the first link and the at least one second lug of the second link being adapted to receive a pin extending therebetween. 3. The track of claim 1, wherein the first link includes a pair of first openings laterally spaced apart from one another with respect to the direction of travel, wherein the second link includes a pair of second openings laterally spaced apart from one another with respect to the direction of travel. 4. The track of claim 1, wherein the second link includes a pair of second openings laterally spaced apart from one another with respect to the direction of travel, the angled grouser being positioned between the second openings. 5. The track of claim 1, wherein the transverse grouser of the first link includes a first portion and a second portion laterally spaced apart from the first portion, a lateral gap defined between the first portion and the second portion in a direction lateral to the direction of travel, wherein the angled grouser of the second link is at least partially aligned with the gap relative to the direction of travel of the track. 6. The track of claim 1, wherein the at least one transverse grouser of the first link includes a first transverse grouser positioned on the first surface adjacent the first end and a second transverse grouser positioned on the first surface adjacent the second end, both the first transverse grouser and the second transverse grouser oriented parallel to one another. 7. The track of claim 6, wherein the first transverse grouser of the first link includes a first portion and a second portion laterally spaced apart from the first portion, a lateral gap defined between the first portion and the second portion in a direction lateral to the direction of travel, wherein the second transverse grouser is at least partially aligned with the lateral gap between the first portion and the second portion with respect to the direction of travel. 8. The track of claim 7, wherein a total length of the first portion and the second portion of the first transverse grouser is at least equal to a total length of the second transverse grouser. 9. The track of claim 7, wherein the gap has a gap length less than the length of the second transverse grouser. 10. The track of claim 1, wherein the second link includes a pair of angled grousers, the angled grousers each forming an acute angle relative to the direction of travel, the angled grousers oriented such that ends of the angled grousers proximate the first end of the second link are closer to one another than ends of the angled grousers proximate the second end of the second link. 11. The track of claim 1, wherein each angled grouser has a first end and a second end, wherein the first end is closer to a centerline of the second link than the second end. 12. The track of claim 1, wherein the at least one angled grouser of the second link has approximately the same longitudinal length as the transverse grouser of the first link. 13. The track of claim 1, wherein the second surface of the first link and the second surface of the second link are operable to directly contact a surface of the sprocket. 14. The track of claim 1, wherein the first link includes at least one guide protruding from the second surface in a direction parallel to the direction of travel, the guide being adapted to engage a slot on a support frame to maintain alignment of the first link with the sprocket. 15. The track of claim 1, wherein at least a portion of the first transverse grouser is aligned with at least one of the first openings of the first link in a direction parallel to the direction of travel, and wherein each angled grouser is positioned laterally alongside one of the second openings of the second link.
