Arto, I cleaned behind the battery and fuel tank areas the best I could, and yes both sides were packed with old grass. Luckily there are not any major rust problems in those areas. The battery tray has surface rust and may get repainted during future winter maintenance.
I drained the right side rear axle housing and the main housing, the fluid out of both was a little milky and very dark, good thing I changed it. The left side remains, I stripped the Allen head drain plug so will be ordering new ones for both sides. How I'll get the stripped one out... I'm not 100% sure.
I replaced the water pump with a cheap one from ebay, I hope I don't regret that decision in the future. It was a quick and easy job with the hood, radiator and the radiator shroud all already out of the way. The hoses seem to be in good shape so I am reusing them.
I relocated the hood handle to the center front. The hood isn't making full contact on the left side where the seal contacts, the whole thing is canted a little and I believe it may have to do with being opened from the same side many times. Opening from the center doesn't cause any offset stress.
