I have a question about the hydros on my 36 redhawk wb. This is the first hydro I have had I used to have a belt drive and never used it because it sucked so bad with no reverse. I use this mower maybe for 1-2 hrs a week on gated yards. The question is when you first crank the mower the hydros will barely move the mower but if you just start walking after maybe 2 minutes of walking real slow it picks up and goes as it should. What could cause this or is this normal I know these are cheap mowers but I bought it for $300 used earlier this summer and it has never let me down but I really dont use it that much. I do know these have sealed hydros on them so the fluid cannot be changed so I guess when they are gone you just have to replace them. Thanks for any ideas.
