I check my hudraulic oil before each use of my 751. I try to keep it to the top mark on stick. since i am clearing cedars with sheer i usually break or loosen a fitting every day or so. I added oil and the screen was there then a couple days later I had to add oil again. The lower 3/4 of the screen was gone and it appeared it had cut with a knife or something. What is going on, did the rough tarrain cause it to fail or what? Is it a problem since there is down stream brass fliter just outside the bottom of the tank? Any ideas. Thank you in advance for your help.The unit has 1500 hours and i bought it used about 2 years ago with 1250 hours on it.
