Hello, I was wondering if someone might be able to tell me why the Cat TH83 aux hydraulic circuit is rated at 18.8 gal/min and 1800 psi. The main system is rated at 28 gal/min and 3625 psi. I am interested in purchasing this machine however I am looking at using a bucket mounted concrete mixer that requires 19.8 gal/min and 2320 psi. I was wondering what the reason / limitation is that necessitated this reduced pressure for the aux circuit and if is was possible / advisable to increase the pressure and flow rate to meet my needs or back to main system pressure. Thank you, Mark MSB Inc.
