I have the same problem on a Long 445 tractor. Gnashing of gear teeth is certainly a problem with the engine running, even at a really low RPM. It is likely that your two stage clutch, the stage for the PTO, has allowed the clutch plates to seize together or the clutch is not adjusted properly. Be sure to press the clutch in all the way. Push it really hard. There is the physical clutch linkage that may need to be adjusted to release the PTO clutch or the "PTO" clutch plates clearance may need to be adjusted. Or, simply engage the PTO before starting the engine. It may be a little tough starting if the PTO has a lot of load on it. That works for my fertilizer spreader but it is likely not the best idea with something like a bushhog. You could try a fast move of shutting off the fuel and engaging the PTO lever when the engine RPM drops lower and then turn the fuel back on quickly to "start" the engine. That rarely works for me. I have found that adjusting the clutch plate clearance didn't help. The PTO clutch plates are likely seized together. I did find that when I used an auger in really dense soil the "PTO" clutch would slip a little with the clutch pedal pushed all the way in. Maybe I should try that a little more to let the clutch "slip" and maybe help to free the seized clutch. Best of luck!

There is a small "weep" hole on my model 445 beneath the brake band that should allow a small leak from the axle seal to be handled without wetting your brake band. My weep hole was partially clogged. I replaced the brake bsnd anyway and it didn't help my brake. Yes, you need to remove the wheel and axle. It is heavy and I used an engine hoist to remove and suspend the axle while I worked on the brake. My understanding from reading about that axle seal is that there are some spacers that hold the axle seal in place and these spacers also control the mesh of the "differential" gears. I decided not to remove the axle seal for fear of never getting the mesh of gears correct. zThe seal was only leaking a tiny bit over the years and I just left the seal as is. Best of luck! Paul
