As you are viewing the picture, the tiller is turning CW. This is the correct direction for the sharpened edges of the tines. For safety reasons, this requires the tilling to be done in reverse. You always want the tines to enter new ground on the down stroke side so if you hit a rock or root, the tiller lifts up over the obstruction as opposed to hooking it underneath and probably breaking the drive train. This is the opposite direction from the original walk behind where the downstroke was in front and it was operated in a forward direction. I had to turn the tiller around 180 deg. to get the drive pulley in line with the PTO, therefore the change in direction. Actually it works very well in reverse. I have found I can pull in to where I want to start tilling, put the hydro in neutral, and hold the brake, Then, using the hyd lift, slowly lower the tiller head to the depth I want. Then just using the brake to control speed, let the tiller push the tractor in reverse.
