G1900s weak hydraulics

[straytcat]

I've got a g1900s with a 42 inch front mount snowblower, my problem is the hydraulics won't lift it off the ground. No problem with the mower deck, and it will lift the quick attach without the snowblower mounted no problem. Hydraulic fluid is full. Any advice appreciated. Leaking seals? Thanks.

Just guessing to see what sticks to the wall...
When's the last time you changed the hydraulic fluid filter?
I would think if you had leaking seals you'd find drips or puddles and/or hyd. fluid in other areas of the engine and the level wouldn't be quite "full".
Maybe air in the lines.
