520lxi - Transaxle fluid change problem

Hi all, newcomer to the forum...

I recently acquired my first WH (came with the house), and love it. I just performed my first round of basic maintenance on it, and everything went well except changing the transaxle fluid.

Drained the oil, no problem. Changed the filter, it put up a fight but I won (a large hose runs diagonally across the filter, so you can't grip it from any angle, hard to even get a filter wrench on it). Putting the oil back in, here I have a problem. The first pint or so went right in. The next pint went in slower as air bubbled out past it, but went in at a reasonable pace. The next few pints trickled in over half an hour or so (each).

Now, I have less than half of the 4.5qts in it, and can't get any more oil to go in. Half a pint has sat in the funnel overnight, and shows no signs of taking any more. I suspect I somehow need to bleed out the air trapped in the transaxle, but see no way to do this. :banghead3

Any advice for a newbie?

Also, I have no intention of selling it, but just as a ballpark figure, how much would it cost to replace this thing? A fairly old (10+ years?) 520lxi, with ~300 hours on it... Basically, if something major breaks on it (I in no way claim myself as a skilled mechanic, as you can probably tell from my question :eek: ), should I bother having it fixed, or just plan on replacing it?

I own a 2004 520xi with 475 hours on it. I 've changed the transaxle oil and filter twice so far. I never experienced the problem that you are having with trapped air in the transaxle. I can only suggest loosening the drain plug to release any trapped air, or raise the rear wheels off the ground with a floor jack to turn/rotate the rear wheels with the transmission in neutral??? Are you sure you drained all of the old oil out?

Also, after changing my transaxle oil and filter my oil level would always be changing between low or high on the transaxle dip stick. The difference would be about an 1/8 of inch on the dip stick. It seemed like it took a few weeks of use before the transaxle oil level would keep its mark in the same location on the dip stick.

I don't have any complaints about my 520xi, but I've been wanting to upgrade to a sub compact tractor. My local Toro WH dealer said my 520xi is worth around $2800.00 with the 60" mower deck, 48" front blade and rear sleeve hitch earlier this spring.

Do you have power steering on your 520lxi? You're suppose to check and clean a screen for the power steering. If so, might this be the culprit to your problem. My 520xi doesn't have the power steering option.

Here's another idea. Don't let the funnel set down tight in the fill spout when pouring the oil in. Hold the funnel just above the top of the fill spout when pouring the oil in.
