 Deadlift is primarily a hamstring, glute exercise. The back is used also during the lift, but the majority of the workload should be done by glutes and hams. The problem most likely is you are not getting, for lack of a better term, your ass low enough when the lift is started. After gripping the bar your hamstrings and glutes should be the primary moving force pulling the bar off of the ground. as is often the case, most lifters will slightly bend the knees and do the majority of the work for the deadlift with their lower back and lats.
