This machine had been sitting in a guys barn for over 10 years. Rats had completely chewed the wiring harness up and the area under the seat and the floor was full to the level of the seat with rats nest

So far ive rebuilt the wiring harness minus the hour meter. Ive also done air, fuel, oil filters and oil. Need to drain and refill hydraulic system and change filters. Little machine seems to run well. both clutches work and the left brake is great, right brake is so so. Hoping I can get a little more adjustment out of it. Seems like it is better cold and when it warms up you have to pull a little harder on the stick to get everything to work. It seems like it will be a handy size for around the farm. Only thing that would make it better would be a 6 way blade. This one is hydraulic up and down with manual angle and tilt.
Any specific areas I need to check on this thing for known issues before I start actually using this machine instead of just playing around on it?
