Slight smell of hydraulic fluid

[Steve67]

Sometimes while working my b2601 I get a smell of hydro fluid usually backing up or a tail wind. I have checked the tractor top to bottom for any leaks and nothing. Hydraulic fluid stays full every time I check. Wondering if it’s the vent tube doing it’s thing ? Anyone experienced this

Sounds normal. During regular operation when it's hot the fluid expands and it vents out pressure from the reservoir.
