Checking your fluid level is essentially pointless.

If the hydro was really low on fluid, then you would not be able to move the tractor. Simple as that.

I agree that you do need to locate the fill plug but you also need to locate the drain plug IF.....your hydro actually has one. If it does, then go cut your grass so that you warm up the hydro as much as possible. Then slide a drain pan under it and remove both plugs. Let it sit for at least an hour to get out as much of the old oil as possible.

Install the drain plug and then refill the hydro with the CORRECT amount of CORRECT fluid. Check with Hydro-Gear's website or a Hydro-Gear dealer on both issues so that you know to a certainty that you are doing it right.

It might call for 10'w30 or 20W50 or even one of the ATF fluids. While oil does not really wear out, it does change viscosity thanks to heat, time and shearing. Fresh oil MAY make a huge difference. If it doesn't, then the hydro's pump and drive motor are worn to the point that speed is suffering. Either a new hydro or a rebuilding will cure that problem.

If there is no drain plug at all on your hydro, then remove the complete axle and drain the hydro using the fill plug. PITA... I know but ......... the longer you leave that old oil in there, the worse your hydro will get. Clean oil will extend the life of your hydro.

Today's Featured Article - Product Review: Electronic Ignition - by Staff. Oil, for example has come a long way in the last 50 years and I don't use anything but the latest API grade available. I've heard the arguments for non-detergent oils but would never trade it for today's formulations. Paint is another, the modern acrylic enamels are great for resistance to grease and fuel stains, retaining their shine and they last forever; unlike enamels and lacquers . Still another is the alternator. No doubt using the original generator keeps the tractor pure, but for thos ... [Read Article]
