Restoring an old horse

This is my 1976 Troybilt Horse rototiller that has seen alot of service over the last 50yrs and has tilled many a garden. It has been in need of restoration for some time..Many oil seals leak--parts needed replaced and a new engine. WD 40 has made this project much more feasible since most if not all the nuts and bolts were very rusted in place. Am pleased to restore such an enigmatic piece of equipment rather than replace it.
