Well a little progress. It seems to be charging ok. Some starting and stopping over the last couple of days, to see if the battery goes flat. Been ok so far. May be a switch fault as suggested to me.
Plastic fender etc removed and the trans drained of milk. Gave the whole tractor a pressure wash this morning and got all the grease and grime off. Looks better already. I found when checking tyre pressures that the rear wheels are water ballasted. It will be getting ag tyres at some stage, as his woodland is quite hilly mainly.Trans has yet to be flushed with diesel, when I have something to sit on. Also engine oil to change. Everything else is well greased.
My mate is getting another fender. Steel one. When he gets over, I'll see how far he wants me to go and give him a list of what's required. Not much really, but another seat and steering wheel are at the top. Maybe a switch also.
One good thing is the tin ware is in good condition. No holes I can see or bad pitting. Just surface rust that sands off. But painting will be up to him. Depends on how soon he wants to put it to work. Nothing to stop it being used as it now is.
