Just got a Bobcat 751B, rental fleet used at 1300 hours. Everything seems in great condition. The Serial # is 515730345. I'm looking for the operation and Maintenance Manuals for this serial number sequence. I only seem to be able to find manuals that say S/N 515716800 or higher. But does this go far enough???? It has a Kubota engine and what does the "B" mean in 751B? Where do I get the manual that will be for my 751 that will cover the S/N I have? Thanks and Regards Bert
