Changed the hydro oil in the 310 yesterday.
First weird thing is that Deere specified a specific filter for the system. Deere sold me that part. It is not the same filter as on the tractor, and does not fit. I had to drain out the new filter as I had pre-filled it before installing it, and will have to lug the old one back to the dealer to match it.
Second, the system drained out about 12 - 13 gallons of fluid. Since I only had Home Depot buckets to catch it, I had to remove the hose assembly loop from the frame (which necessitated removing a munged up, rusty bolt), and removing a finely threaded plug. Getting the plug back installed while fluid was pouring out so I could switch buckets was an exhausting nightmare.
So I went to Home Depot, and bought a 3/4 inch gas valve, rated for oil. I chose the gas valve because there was not enough room for a long handled ball valve. Bought two, 3/4 nylon hose barbs, and some oil resistant heater hose. I have brass barbs on order, but will use the nylon (which Home Depot stocked) for one year. The valve will let me easily stop the flow while I change buckets.
With the number of hours expected to be low each year, I’m guessing that this will be a yearly chore, but it was worth $30 in parts to not risk dropping a plug, or doing something else to pour 12 gallons of oil onto the driveway.
