3112h hydro questions

[Finkbeinerpulling 0]

alright my 3112 vickers hydro leaks in the same place everyone elses does but the last 2 times i have mowed lawn with it it makes a moaning sound, not like the normal hydraulic system whine but deeper and all through the rpm range. i know its the hydro because when i push the clutch pedal it stops. other than the moan/hum it runs fine(except for the blastd leak!!!!!) is it possible that it needs a filter?

It is possible that filter needs replaced and fluid is low. Wix filter number 51467 is equivalent to Purolator number H202247. If it is leaking bad I would save spending $50.00 on an OEM filter.
