Question about Troy Bilt Tiller/Edger 26cc, Model No. 21at144r766
Since there is no grinding noise, if the problem is in the gear box it isn't too severe. There is a slight possibility that a tooth or two has been broken off one of the gears. But it sounds more like you have a worn drive belt. Most of the time when the tines don't grab or they slip it is because the drive belt have become worn in some way. If it is suppose to be a one-half inch wide belt it could have thinned to a three-eight inch allowing the belt to drop further into the pulley than needed, or it may be "sloppy", not tightening enough to operate the tines if it has stretched. The right belt is very important and is an easy fix. I hope this helps.

When you try to engage the tines with the lever above the left hand rear side is there any noise if you do this with the motor running and the drive unit in gear? I need more info than you have given to suggest a proper repair.
