Been using the new mower for a couple weeks now. So far I love the mower. Its great. Its quick. Even being a 48 in deck it is quick. I removed the rops. Have low hanging branches. Only thing that needed fixed was the hour meter. All fixed now. Haven't torn to much grass when turning. Its a learning experience. It strips farelly decent. Could be better but its the first few cuts of the year. Looking to get a turbo pro collector for it but financial department (girl friend) said maybe next year.
The "drown" is probably just your hydraulic pumps. Try pointing it up hill and slowly engage forward movement. You will probably hear the same noise. I don't think it's anything to worry about. gregjo1948
