I started mowing the wheat stubble with the Massey Ferguson 35 and bush hog today, the oil pressure seems low on that old tractor? when I got it the PO replaced the oil pump, the tractor doesn't smoke or burn oil, it's a nice running old tractor. The oil gauge is always on 20, after it's run for several hours it drops to around 15 to 10 and that's when I shut it down.
Just recently the tractor started leaking oil from under the dash and onto the shifter. I'm guessing the pressure gauge is leaking? maybe that's why it shows low pressure? I'm not going to run it any longer till I get it sorted out on what it is.
The old tractor was also getting a little hot on me today, I dumped in 3/4 gallon of water but it was still getting close to the red mark on the gauge. If I ran the tractor at a low throttle it seemed to run the right temp, but as soon as I sped the engine up the gauge would start climbing. I might try washing out the radiator, I've been doing a fair amount of mowing with it so maybe it's plugging up.
As you can see in the pictures of the oil leaking, the oil is super dark black, but when I check the oil on the dipstick, the oil couldn't be cleaner looking???.
The oil seems thin to me, I don't know what the PO put in it for oil, I'm going to check the oil tomorrow when the engine is cold, I might just drain out the oil and start over. Does anyone have any ideas???
I'm needing to get this sorted out fairly soon, I have 10 acres that needs to be plowed and I don't want to have any issues once I get started.
Thanks for any help
