I dont' think John Deere makes these type systems (John Deere Hydraulic Dump Material Collection System Power Pak) any more but does any one have any information on where I can look to purchase on of them? Or am I wrong, do they still offer them here in the US?? I do not want to buy the one they are offering for the 2520 which is the 3 bag type (14 bushell). I have no interest in getting off the mower while I am mowing.
