A track pad for a crawler, especially operating in a landfill, having a generally rectangular base plate with holes for attachment to a track chain link, the base plate having front, rear and side edges, a high rise grouser on the base plate, the grouser projecting from the base plate a distance substantially greater than conventional grousers, the grouser having a central portion with the general configuration of a plate with an edge distal from the base plate, the central portion being generally laterally centered on the base plate, the grouser being devoid of areas projecting significantly from the base plate adjacent the side edges of the base plate.

1. A track pad for a crawler having a generally rectangular base plate with holes for attachment to a track chain link, the base plate having front, rear and side edges, a high rise grouser on the base plate, the grouser projecting from the base plate a distance substantially equal to at least one-half the distance between the front and rear edges of the base plate, the grouser having a central portion with the general configuration of a plate with an edge distal from the base plate, the central portion being generally laterally centered on the base plate, the grouser having side portions that gradually reduce in height above the base plate with decreasing distance from the base plate side edges, any outside corners of the combined peripheral edge of the central portion and the side portions distal from the base plate and viewed in a vertical plane being obtuse so as to avoid sharp corners such that the central portion and the side portions avoid debris build-up causing projections adjacent the base plate side edges. 2. A track pad as set forth in claim 1, wherein the grouser locally projects a vertical distance from the base plate not more than one inch plus a horizontal distance from an adjacent side of the base plate. 3. A track pad as set forth in claim 1, wherein the grouser side portions lie in respective planes oblique to the central portion. 4. A track pad for a crawler having a generally rectangular base plate with holes for attachment to a track chain link, the base plate having front, rear and side edges, a high rise grouser on the base plate, the grouser projecting from the base plate a distance substantially equal to at least one-half the distance between the front and rear edges of the base plate, the grouser having a central portion with the general configuration of a plate with an edge distal from the base plate, the central portion being generally laterally centered on the base plate, the grouser including side portions on each side of the central portion, the side portions lying in respective planes oblique to the central portion, the side portions being triangular gusset shapes projecting from a surface of the base plate gradually to the level of the central portion. 5. A track pad as set forth in claim 4, wherein said side portions are in laterally outwardly directed planes oblique to the base plate. 6. A track pad as set forth in claim 1, wherein the grouser projects vertically from the base plate a distance not greater than a projecting area of the grouser is spaced from an adjacent edge of the base plate. 7. A track pad for a crawler having a generally rectangular base plate with holes for attachment to a track chain link, the base plate having front, rear and side edges, a high rise grouser on the base plate, the grouser projecting from the base plate a distance at least four inches above the bottom of the base plate, the grouser having a central portion with the general configuration of a plate with an edge distal from the base plate, the central portion being generally laterally centered on the base plate, the grouser having side portions that reduce in height above the base plate with decreasing distance from the base plate side edges, any outside corners of the combined peripheral edge of the central portion and the side portions distal from the base plate and viewed in a vertical plane being obtuse so as to avoid sharp corners such that the central portion and the side portions avoid debris build-up causing projections adjacent the base plate side edges. 8. A method of retarding the build-up of debris in the roller frame of a crawler when operating in a landfill comprising using track pads having a grouser projecting from the main pad body a distance of at least four inches at a central portion and at side portions projecting less than one inch adjacent the side edges of the main pad body, any outside corners of the combined peripheral edge of the central portion and the side portions distal from the base plate and viewed in a vertical plane being obtuse so as to avoid sharp corners. 9. A method as set forth in claim 8, wherein the central portion of the grouser is reinforced with the side portions obliquely oriented to the central portion. 10. A method of retarding the build-up of debris in the roller frame of a crawler when operating in a landfill comprising using track pads having a grouser projecting from the main pad body a distance of at least four inches and projecting less than one inch adjacent the side edges of the main pad body, a central portion of the grouser being reinforced with gusset portions obliquely oriented to the central portion, the gusset portions being triangular in profile and being arranged obliquely to the main pad body. 11. A method as set forth in claim 10, wherein the gusset portions are arranged to trail the central portion of the grouser. 12. A method of retarding the build-up of debris in the roller frame of a crawler when operating in a landfill comprising using track pads having a grouser projecting from the main pad body a distance of at least four inches and projecting less than one inch adjacent the side edges of the main pad body, a central portion of the grouser being reinforced with gusset portions obliquely oriented to the central portion, the gusset portions being triangular in profile.
