i would say no!
have you checked your lift/transmission oil level
with the tractor parked on level ground and having been setting for at least 30 mins for the oil to run down.
have the lift arms in the up position with no load (as my old fergy, if you have a load on the lift arms they will go down in a few mins).
that method should give you the correct oil level in the sump.
have you changed oil lately in the sump, if so did you use the correct oil, not some low budget oil from the auto parts store.
what is the correct oil for your tractor?
my old Fergy takes GL-1 oil for the rear sump
