My L-245 2 WD utility tractor has 2 bolts about 2 inches apart screwing into the left side of the transmission, just inboard of the clutch pedal. Both have 12mm heads. One of them is to check tranny/hydraulic fluid level. The other is for????. The picture in my after-market maintenance book is dark and does not show which bolt is the correct one to check fluid level. Fluid pours out of one of them; the other is dry of fluid when I unscrew it. Does anybody know how to find out which is the correct bolt to check tranny fluid level? I am afraid that I have too much or too little fluid in there, either of which could ruin the tractor.
