There she blows, a 4016 oil leak

1-1/2 hours mowing the neighbors yard followed by one round on our yard. Suddenly the deck was engulfed in oil.

Finding the leak was out of the question while the engine and oil were hot. It adds about 30 minutes mowing time when using th 446 and 48" deck but given that we were hosting a canasta party that evening, the mowing had to be finished.

With the inspection/cooling panels off nothing no problems were observed.

Even with the deck on it, there was a visible leak on the line connecting the pump to the tcv.

Having a forklift is the easy way to remove a 60" deck. This hose replacement turned out to be an easy fix.

That is one hose I somehow least expect to fail. AND that's why it probably happens. :roll: But I'm glad it wasn't something worse, which I was afraid of when I started reading your post Eugene. Phew! Now, isn't it nice when starts align you happen to have a spare of that exact hose? :thumbsup:

@Eugen It could have been much worse. The hydraulic tank was nearly empty, even with shutting down as soon as the leak was spotted. I was tempted to drive it back to the garage and that could have lead to pump damage. The tractor would have stopped moving when the tank emptied.

Glad you got it fixed :thumbsup:

Not to hijack your thread but it's related... When I first installed my rear PTO a slow leak at one of the fittings developed after I started mowing. I was probably mowing for a half hour when I slowed for a turn my tractor made a jerking motion. I stopped and checked under the tractor. It was dripping quickly. I just shut it off, refilled it and it's been fine for the past 5 years.

When it rains, it pours oil. I don't know the source of the leak this time.

My guess is the hose between the tank and pump.
