I am looking for a WORKSHOP Manual for a "Prime Mover model M-15B" This is an older Concrete buggy with a Wisconsin engine; later a Kohler engine with manual dump and push steering. I believe a 1950s or 1960s model. They were built well. The Prime Mover Co. Was bought & changed name several times and I believe they are now BT Raymond. It Still works OK but I need to adjust the clutch's, there are two, one for forward & one reverse. And I would like to know what oil goes into the tranny. I contacted BT Raymond but no response yet. This will be for my personal use only. I sure could use some help. Thank you every one..... WRT
