Thanks for the information on how much to fill up the radiator. Again, I admit that I am a novice and may just be overreacting because of just how much water/fluid gets flushed out (at least half of what should be in the radiator). I worry that it is getting too hot.
The power issue though is real. We use to use the tractor for everything! It was the family workhorse. Now there is no way to even plow the garden. As soon, as the blades get into the ground it stalls out and dies. Using the mower bed underneath was great because you just increased the fuel and you could cut just about any heighth grass with ease. Now it bogs down and can barely make it through what it use to cut with ease.
How do I test/fix the compression?
I've had the had redone with new gaskets all around.
I agree that it sets for a long time between uses.
