I am in serious need of a manual for this very old but fantastic rear tine tiller. It is a BEAST of a tiller and does a better job then any tiller currently made. It has 5 speeds fwd and 1 speed reverse. You can disengage the tines seperatly from the drive wheels and vise versa. I will re-post this again after I have a picture or two of the unit. submitted 25 june 2010
