1. An attachable track overlay apparatus attachable to an extant track of a track machine, said attachable track overlay apparatus comprising a parallelepiped member releasably attachable within a track bed of said track, said parallelepiped member having a hook member disposed endwise at a first end thereof for hooking engagement to the track of an extant track machine, a lock member disposed endwise at a second end of the parallelepiped member for releasable securement thereto, said lock member having a brace member disposed endwise upon the parallelepiped member and a base member rotatably disposed underlying the brace member, wherein rotation of the base member between an unlocked position and a locked position releasably secures the parallelepiped member to the track when a lock pin is forcibly engaged into a second depression disposed upon the brace member, said lock pin positional to the second depression when the base member is rotated to the locked position, whereby a rubberlike pad disposed overlying the parallelepiped member is disposed for tractable engagement with a ground surface during operation of the track machine and the parallelepiped member is removable therefrom when the base member is rotated to the unlocked position. 2. The attachable track overlay apparatus of claim 1 wherein the lock member further comprises: a channel disposed in an undersurface of the brace member, said channel disposed between a shallow first depression and the second depression;a cylindrical cavity vertically disposed in the base member, said vertical cavity including a spring member tensionally engaged against the lock pin therein disposed, said lock pin oriented to travel within the channel between the shallow first depression and the second depression when the base member is rotated between the unlocked position and the locked position;a first insertion hole disposed in a lateral surface of the base member;a second insertion hole disposed in the lateral surface of the base member in a perpendicular situation relative the first insertion hole; anda handle member attachable within the first and second insertion holes, said handle member positional therein for rotatable engagement of the base member between the unlocked position and the locked position;wherein the handle member is usable to effect rotation of the base member between the unlocked position and the locked position for releasable securement and selective release of the parallelepiped member to the track of a track machine. 3. The attachable track overlay apparatus of claim 2 wherein the brace member and the base member are hemicircular, said base member rotatable within a plane parallel with respect to the brace member and rotational thereat for lateral extension therefrom for engagement underlying the track when moved from the unlocked position to the locked position. 4. The attachable track overlay apparatus of claim 3 wherein the channel includes a sloped section proximal the second depression, whereby the lock pin travels into the second depression down the gradient of the sloped section when the base member is rotated to the locked position, said lock pin compressed into the cylindrical cavity by travel up the gradient of the sloped section against the action of the spring member when the base member is subsequently rotated to the unlocked position. 5. The attachable track overlay apparatus of claim 4 wherein the cylindrical cavity includes a grease fitting accessible by removal of a bolt member disposed enclosing said grease fitting for addition of grease thereinto, whereby lubrication of the spring member and lock pin, and exclusion of particulates from the cavity, is effected. 6. The attachable track overlay apparatus of claim 5 wherein the lateral surface of the base member includes a diametric surface and a circumferential surface. 7. The base member of claim 6 wherein the first insertion hole is disposed in the circumferential surface proximal the first depression and the second insertion hole is disposed in the diametric surface proximal the second depression in a perpendicular orientation relative the first insertion hole. 8. An attachable track overlay apparatus attachable to an extant track of a track machine, said attachable track overlay apparatus comprising: a parallelepiped member having a first surface, a second surface, a first end, and a second end;a hook member disposed endwise at the first end, said hook member comprising a vertical section disposed endwise at the first end and an overhang portion disposed endwise upon the vertical section, the overhang portion thereby disposed in a plane parallel with the second surface of the parallelepiped member;a lock member disposed endwise at the second end, said lock member comprising: a hemicircular brace member disposed parallel with the parallelepiped member, said brace member having a an undersurface;a channel disposed in the brace member undersurface, said channel disposed between a shallow first depression and a vertically oriented second depression, said channel including a sloped section disposed gradiently into the second depression;a hemicircular base member disposed underlying the brace member, said base member rotationally disposed thereat and moveable between an unlocked position underlying the brace member and a locked position rotated laterally therefrom;a cylindrical cavity vertically disposed in the base member;a depressible lock pin compressibly disposed in the cylindrical cavity against the action of a spring member, said lock pin traveling between the shallow first depression and the second depression along the channel when the base member is rotated between the unlocked position and the locked position;a bolt member removably disposed enclosing a grease fitting disposed accessing the cylindrical cavity, said bolt member removable therefrom for addition of grease into the cylindrical cavity for lubrication of the spring member and lock pin and the exclusion of particulates therefrom;a first insertion hole disposed in a circumferential surface of the base member proximal the first depression;a second insertion hole disposed in a diametric surface of the base member proximal the second depression, said second insertion hole disposed perpendicularly relative the first insertion hole;a handle member releasably attachable into said first and second insertion holes for pivotal engagement of the base member between the unlocked position and the locked position; anda parallelepiped rubberlike pad disposed upon the first surface overlying the parallelepiped member;wherein the hook member hooks to an extant track of a track machine and the parallelepiped member releasably overlies a track bed of said extant track, said parallelepiped member releasably securable thereat when the base member is rotated by action of the handle member to the locked position, the lock pin thereat forcibly inserted into the second depression of the channel by action of the spring member when the base member is rotated to the locked position, whereby the rubberlike pad is disposed overlying the track bed for tractable engagement with a ground surface and the parallelepiped member is removable therefrom when the base member is moved to the unlocked position.
