Howdy fellas! I'm new to posting but have been checking out several forums here for some time now (tons of info) so, it's as good a time as any to jump in. I apoligize for any blips in advance.
I have a Deere 2520-same tractor I'm guessing-so I can relate. 35 pounds at almost arm length is a pain in the keester during peak grass growing season! What I did was get a "DELTA" brand 50 gallon square transfer tank-2x2x2 feet with a 12V pump. Build a dolley of 2x4's with 4 casters for it to set on.I roll mine under the end of the work bench for storage.The pump will probably come pre wired with alligator clips, mine did. I use an old battery from the boat but you could just as easy use the tractor battery and not mess with the extra battery issue. At the begening of the season I use a couple nylon chokers and the FEL to load the tank in the truck, fill it at the station, and reverse the process back home. I mow 2 acres 3 maybe 4x every 2 weeks and I can go most, if not all season on a tank. Works great, takes little space, and no need for delivery.
