Hello! I'm working on a Craftsman DLT 3000 w/ a Peerless H2000-006A Silent-Trac transaxle. I wanted to know what fluid I should use in the pump? From what I found, the tractor takes Mobil 424 Hydraulic Tractor Fluid. I was considering using John Deere Hy-Gard though, as I'm thinking it may be better for the tractor. I also wanted to know if I should use the low or high viscosity Hy-Gard if I do get it. Thanks, Ashton.
