Hello I am new to the forum and new to tractors. I just got a L245DT with a loader. It has been sitting for about 8 years so I am in the process of looking it over and changing fluids and filters. The cover was off for the PTO shifter ( the cover with the shift pattern on it ) so when i looked in the transmission case I saw a piece of wood in the transmission. Looks like a 2x4 that has been shaped to fit. Question is is it suppose to be there and if not why would it be there? Just want to know before I fill up the transmission.
