    I recently purchased a 48" Bob-cat walk behind mower (belt drive w/out selectable gear transmission). The model number is XM4806 Serial number is 00401.
    This mower has definitely seen better days, and I would like to start doing some of the repairs that the previous owner neglected. The first problem I am having is with the ground speed control lever. The linkage rod just seems to bend instead of applying pressure to the drive belt, and the mower does not move very fast, and wont pull its self up hill. I see that there are two adjustment but have had no luck increasing the tension to the drive belt. I have tried getting a repair manual from Jacobsen Publication Zone on-line, but I cant locate my model. I was hoping to find a .pdf version of the repaid manual if anyone could point me in the right direction that would be cool.

    I don't know about a service manual but you should check this thread out, It may help you with your problem.
    While you were looking for a manual did you happen to find a on-line source for parts look-up and purchase ?

    your problem could be that the drive belt is not routed correctly on the pulleys look at the pics in that thread and make sure it looks like that if it looks right your best bet on fixing your problem is just to simply replace all the drive belts since they are probobly worn/streched and could even be originals, there is one that connects the engine to the trans and one for each wheel that connects the trans to the wheel my 36 bobcat has the same problem with the hills i somtimes have to press down on the pistol grips to tension the trans to wheel belts because they are very old and need to be replaced they are only $27 a piece from that site and i plan on replacing them shortly

    On these ransomes mowers there is a "varible speed tension pully", it is a spring loaded pullythat chages the belt ratio. It bolts right on to the shaft of the engine, under the blade belt pully. The varible pully rusts up and doesn't move, giving you only one speed. You'll need a gear puller to get it off. This will give you your speeds back.
