So, just had Terry go through my photos...
1 Is the cooling fan relay - No service needed
2 - Is the charging circuit. I still don't completely understand how this works (anyone?) but it increases the pressure to the system. Yes it can leak and may need a repair down the road
3 - Some sort of manifold blaock. Puts oil back in the system
4 - PTO activator and steering activator. Terry says that mine does not have the steel ball that would need to be looked at. Boy it looks just like sedgewoods but I am not messing with it.
5 - Draft control. No maintenance other than adjusting mower height.
6 - Yup I have a 2nd filter on my PT. 10 Microns, replace once a year. It is in line with the steering I think he said.
Well, there we have it. Another lesson learned.
