<font color=blue>when I apply down pressure to smooth out the surface and then release the pressure I hear a rather loud, squeecky (excuse spelling) noise. </font color=blue>
Here are a few things you might check:
1) Have you greased all your loader's zerk fittings lately?
2) Extend your bucket curl and then lightly oil your hydraulic rams to see if that changes the sound. After checking, repeat with loader's lift arms.
3) Check that the loader mounting brackets on each side of your tractor have tight bolts. This takes a big socket and they are hard to get to, but I found a couple of loose ones on my tractor.
4) Check the greasing on your front axle. Down pressure lifts the front of the tractor and releasing it lets the tractor down. The front axle might be squeaking as it settles to the ground.
These are not "scientific" suggestions, but just checks on areas that move when you operate your loader as described. The "squeak" isn't the loader scraping on top of the gravel is it? Good luck!/w3tcompact/icons/smile.gif
