Finally took the oily puddle under the tractor seriously. I had thought the oily spot was just melting hot grease from the mower bearings (I do grease those up), but I finally climbed under after moving the hot tractor and seeing the new drips under the rear of the tractor, under the seat. It’s dripping off of the hydraulic line at the low point there, quite wet and oily with it. The transmission oil dipstick is only about halfway down the hatched area, so it’s not too bad. But bad enough to fix.
So like I said, it’s very oily at the lowest point, but that could be coming from anywhere above it. Following that line up, it comes out of the transmission on the right side, above the right rear tire. At the high point it’s a little bit oily but not as aggressively leaking as I see coming onto the ground, at all. As near as I can see the whole cover of the line is pretty soaked in UDT. I wrapped a paper towel around it ant the top/transmission connecting points and mowed a little, and none into the paper. So maybe down lower? Cumulative leaks from multiple points? I checked with a wrench, and nothing I can reach seems loose on the lines.
130 hours on it, I guess 4 years old. I’ve had 18 HP Kubota diesel tractors for 25 years now, the old one was really old. This new one has been perfect up to now.
I assume the lines are intact and there are O rings or couplers or something in there? Or maybe a line has a crack? Seems too new for that. I searched the forum and YouTube, but there is so much about hydraulic leaks, hard to sort through and I didn’t see anything about this spot.
Thanks for any wisdom!
