Hi Paul, You mentioned Finn additives in an earlier thread. I have found their tack is really good and will try the Hydro Max this season for sure. I know you run a Finn T-60, which is now what I own also. My question: Have you used the Finn moisture retaining product...I forgot what it's called but will the T-60 handle 250 lbs of wood mulch AND those granules? I believe they swell when wet so I am interested in knowing first hand whether the machine will pump it. I have 150 feet of hose. Thanks!
