         7 . The adjustable blade rake of  claim 1 , wherein the plurality of tines are removable by removing the crossbar and sliding the plurality of tines upward out of the plurality of slots. 
     
     
         8 . A rake system comprising:
 a mounting plate configured to mount to a machine;   a backup plate coupled to the mounting plate, the backup plate having a plurality of slots;   a moldboard having a front side and a rear side, the rear side of the moldboard attached to the backup plate;   a plurality of tines slidably located in the plurality of slots adjacent the rear side of the moldboard;   a crossbar coupling the plurality of tines together; and   a height adjusting system operatively coupled to the plurality of tines and configured to selectively allow the plurality of tines to slide in the plurality slots between a retracted position and an extended position as the moldboard is raised and lowered by the machine.   
     
     
         9 . The rake system of  claim 8 , wherein the height adjusting system includes a removable pin. 
     
     
         10 . The rake system of  claim 9 , wherein pin is received through an aperture in a sideplate and through one of a plurality of apertures in one of the plurality of tines. 
     
     
         11 . The rake system of  claim 8 , wherein the moldboard includes a ground engaging material coupled to a lower portion of the moldboard and the plurality of tines includes a ground engaging tool coupled to a lower portion of the plurality of tines. 
     
     
         12 . The rake system of  claim 8 , wherein the plurality of tines have a profile shape substantially similar to a profile shape of the moldboard. 
     
     
         13 . The rake system of  claim 8 , including a second backup plate coupled to the mounting plate, the second backup plate having a second plurality of slots, the second plurality of slots aligned with the plurality of slots in the backup plate and slidably receiving the plurality of tines. 
     
     
         14 . The rake system of  claim 8 , wherein the plurality of tines are removable by removing the crossbar and sliding the plurality of tines upward out of the plurality of slots. 
     
     
         15 . A machine comprising:
 a frame;   a power system supported by the frame;   a propulsion system coupled to the frame and the engine, the propulsion system configured to propel the machine; and   an adjustable blade rake coupled to the frame, the adjustable blade rake including;
 a mounting plate configured to mount to a machine; 
 a backup plate coupled to the mounting plate, the backup plate having a plurality of slots;
