@spiesspullingteam: Other things to mention about cement pulling: there are no “stock” or “modified” classes. Only weight classes, and some classes may or may not have a tire size limit is all (which is usually 18.4 width limit or open tires). Also, all mid-michigan cement pulls have the same rules at each cement pull a club may host. What makes cement pulling awesome is that it has hardly changed since the 1940’s, only the tires got bigger, and the tractors are running better! #tractor #tractorpulling #pulling #cementpulling #stock #stocktractor #farmstock #farmtractor #spiesspullingteam
