Need help identifying a leak please

[StrangeRanger]

Hi all,

Since it doesn't seem to snow in VT anymore I've not used my L3400 for a couple of weeks. But I walked by it the other night and noticed a very small "puddle" under it. It's not pooling up and it was only about 4-5" in diameter so whatever is leaking is leaking very slowly.
It's under the left side, just about right behind the step up on to the tractor. At quick glance I thought it was my sight glass leaking cuz it's in that area. But when I ran my finger around the sight glass it's bone dry.
I looked quickly underneath but I can't notice anything easily.
Does anyone know what's on that side of the tractor that could be leaking very slowly like that?
Thanks,
j

I believe that there are a couple hydraulic hoses that run underneath the orange center cover. If i remember correctly there is a filter located below the left side step. One of the lines from the filter fits in to a hole in the side of the transmission case that is sealed with two o-rings and a flange with a bolt through it. Also check the trans case seams.

Post a pic if you can.

There is an HST filter on that side with a hard line that enters the transmission case close to the site glass. Also a leaking sight glass will leak between the glass and the fitting, not the fitting and the case. It can leak and not get fluid on the transmission case so check the lower edge on the front of the sight glass.
