Just bought a 200 that's in great shape for being unrestored. My first red tractor and I'm really looking forward to "sprucing it up". It has both wide and narrow fronts, two point, and standard hitch. I plan to give it a new coat of paint but want to take care of any mechanical items first. There is a transmission leak between the rear frame and clutch housing - just in front of the platform. I have a parts book and it looks like there's a 1 1/4" dia. plug in an idler shaft hole. Is this likely the cause? I assume it has to be split? If so, anything I need to be aware of? Any help is appreciated.
