Hi all, I just purchased a B8200 HST-D that I saw for sale and finally gave my wife enough reasons I should own it! It shows 150 hours, but who knows if it has turned over. It leaked very dirty black oil from the breather pipe and I found the oil pressure sensor wire was unplugged. When I plugged it in the light came on (of course), but it would go out if you throddled up the engine. When I drained it I got almost 5 quarts out, the manual says it takes 3.3 so I'm guessing thats the reason for the breather pipe leak, but with fresh oil in it the oil light is still on at low rpm's. The new oil also looked very dirty on the dipstick after only a min or so of running. I now have a new oil filter from the dealer and am going to change the oil and filter (didn't have filter yet on first change). Can the filter cause this low pressure? Is there a way to flush the block out? This is my first tractor, but I am pretty good with fixing things. Thanks for the help!
