What I have seen done and much cheaper.....get a length of pipe with same thread, but long enough to clear your wheels. ( I think galvanized pipe is easy available at CTC or Home Depot, Home Hardware) Thread that end and put on a brass rad **** (from CTC) on the outboard end, (or use a ball valve.. maybe a bit too big? & overkill)
You can now change oil without spilling oil on the wheels, tractor, or the driveway. Best part ... no wrench to drain oil needed. I would worry that that hose were to crack in cold temps & you trash your engine.
Hope this helps
