I am new to the forum and to kubota tractor's. I just brought home my b6000 grey market tractor today. It seem's to be a nice little simple machine. I have a few question's on the machine. The tiller looks to be permanantly mounted to the machine, is it possible to change 3pth implements. what is the grove in the front of the tractor for (looks like a front pto maybe). there doesn't seem to be an air filter in it just a glass that can be dumped out, is this correct or am I missing something. And what type of fluids go where. I do plan on ordering a service manual and will be doing alot of searching on this forum to help me with these questions and to learn more about this machine.
