I know this topic has been covered but I can’t seem to find the old threads. As I recall there are two issues when mowing with Onan hydros.
I understand grass accumulation can occur quickly in the flywheel screen and then move to the rear cylinder cooling fins causing overheat problems on the rear cylinder. I also read that the rear discharge unit tends to throw grass clipping at the Hydro fan unit possible causing over heating issues with the pump? Also recall that some add a piece of vinyl baseboard molding to the RD deck to deflect the clippings away from the hydro unit?
I recently picked up a 1995 520H which came with the rear discharge deck. I also have a an extra 48” side discharge deck that I use on my 314-8 tractor. I think I will be mowing with the 520H unit this summer and am curious which style deck you guys recommend I use and why?
