       9 . A mobile hopper assembly towable by a vehicle, the assembly comprising:
 a frame;   a hopper fixedly attached to the frame;   a plurality of legs attached to the frame, each leg including a movable portion that is movable to move the hopper between a portable position, a partially raised position, and a raised position; and   a wheel coupled to the frame that at least partially supports the hopper when the hopper is in the portable position.   
   
   
       10 . The mobile hopper assembly of  claim 9 , further comprising a trailer assembly removably coupled to the frame and the vehicle that at least partially supports the hopper when the hopper is in the portable position. 
   
   
       11 . The mobile hopper assembly of  claim 9 , wherein the plurality of legs includes four legs. 
   
   
       12 . The mobile hopper assembly of  claim 9 , wherein each leg includes a stationary portion having a first aperture, and wherein the movable portion includes a plurality of second apertures. 
   
   
       13 . The mobile hopper assembly of  claim 12 , wherein the movable portion of each of the plurality of legs is individually movable. 
   
   
       14 . The mobile hopper assembly of  claim 12 , further comprising a securing device coupled to each of the plurality of legs and operable to inhibit movement of the movable portion with respect to the stationary portion. 
   
   
       15 . The mobile hopper assembly of  claim 14 , wherein each securing device locks each of the plurality of legs to position the hopper in one of the portable position, the partially raised position, and the raised position. 
   
   
       16 . The mobile hopper assembly of  claim 14 , wherein each securing device includes a peg engageable with the first aperture and one of the second apertures. 
   
   
       17 . The mobile hopper assembly of  claim 9 , further comprising a dispensing device coupled to the hopper. 
   
   
       18 . The mobile hopper assembly of  claim 17 , wherein the dispensing device has multiple open positions. 
   
   
       19 . A mobile hopper assembly towable by a vehicle, the assembly comprising:
 a frame;   a hopper fixedly attached to the frame, the hopper including a converging portion and a dispensing device;   a plurality of legs each including a stationary portion attached to the frame and a movable portion that is movable with respect to the stationary portion between a retracted position and an extended position;   a plurality of locking devices each associated with one of the plurality of legs to selectively inhibit the movement of the movable portions with respect to the stationary portions;   a wheel coupled to the frame to at least partially support the hopper when the movable portions are in the retracted position; and   a trailer assembly coupled to the frame and the vehicle that at least partially supports the hopper when the movable portions are in the retracted position.   
   
   
       20 . The mobile hopper assembly of  claim 19 , wherein the plurality of legs includes four legs. 
   
   
       21 . The mobile hopper assembly of  claim 19 , wherein each movable portion is individually movable.
