oil level

[tommyg 152]

The manual for the d-180 calls for 6 quarts of oil in the transmission. When I do that, it's well above the full line. When I start the tractor, it seems normal. If I only fill it to the full line, then start the tractor, it's way below the full line. What's right? I've been using the 6 quart recommendation on a "dry" transmission (assuming all the oil is drained down to the transaxle) and have not had any problems, but I don't want to create one either. Any thoughts?

I would go with the dipstick.  The pump and manifold lines may drain down some also you have to fill the hydraulic cylinders..  I fill it to eh dipstick mark then run it for a while and see if it needs more.I do not see any downside to being somewhat over full other than some being pushed out the dipstick

My D does that exact thing with the oil level climbing - I suspect a very small leak somewhere that is allowing the pump or cylinders to drain back into the transaxle and increasing the oil level .

Wouldn't it drain back normally? I'm going to have to check the level right after running it and after sitting for awhile.

Normally , I'd say no - it shouldn't drain the oil back to the axle housing if everything is tight and sealed well , especially the pump and spool valve/cylinders .
