I just picked up Dads old TO30 from his place. Unfortunatly it sat outside for maybe 13 years covered with plastic for some of those till the plastic fell apart. Great running tractor since we got it and Dad rebuilt everything back in the mid 70s. We used it to bushhog heavy brush and small trees and do a lot of grading. Worked it hard for years and only a few small problem no worse than a broke manifold. Now poor girl has the cruddiest gas tank I ever saw and fuel was left on so no doubt the carb is full of crud also. Fuel line rusted out and water no doubt got into the trans and maybe rear end. Moms blue tick hound got under the dash somehow and chewed up all the wiring (Dead Dog!). Dad has the manuals but hasn't found them yet so I need to know what fluids go in the rear end, hydralics, trans etc. Going to take the gas tank off and try blasting it out with a pressure washer and see what I am dealing with, make new steel fuel line, and check carb bowl. She is completely stock down to the 6 volt system which we never had problems with till the dog came along. Paint suffered greatly under that dang plastic. Lot of life left in her so I better get started! PS, I bet I put 20,000 miles on it mowing and hauling firewood on a carryall when I was 9-20 years old! I felt like half my life was spent in that seat! Be sure to let me know about the fluids and what I want is the right type fluids!
