Fluid change in front end of 2520

[BlackRaptor]

Well my 2520 has 75 hours on it now I changed all the main fluids on the tractor at 50 hours oil tranny so on.
But i did not change the fluid in the front end for the AWD.
should i change this before the mowing season starts? I remember someone saying 100 or 150 hours before changing this fluid
Thanks

I'd recommend changing it now based on the metal shavings that "KillerB" found in the front axle of his 3320 after only 50 hrs of use. They may just be metal drilling fragments from the manufacturing process but you still want to get them out of there.

Here's the thread, take a look as it has pictures of the shavings.

Why so early? Not saying good or bad but I had my 650 for 20 years never changed the frontend oil, 1500 hours and a lot of 4 wheel drive. I think the manual states 600 hours.

I changed my 2320 @ around 100 hours.. I just wanted some fresh in there and I also went with Amsoil Severe Gear 75-90..

The oil coming out had a murky color to it, almost like it may have had some water contamination.. My drain valves at each tire were sorta hard to drain without getting oil all over the rims.. I cut the bottom out of a 20oz plastic drink bottle and used that to direct the flow away from the tires into a pan..

The refill is a slow process, at least on the 2320. At times it would get air locked/bubbles and over flow because i was trying to pour too fast. Then it took several days of driving and rechecking to get it all the way to the full mark - I assume it took that long to get it into both wheel cavities..
