    I bought a used ws5223kawe 52" stander last week which I did a full tune up on. The last step I need to do is change the filter and fluid for the hydrostatic system. I know I use mobil1 15w50 for it and I have read a owners manual for a newer stander online. the problem I have is in that manual it said to fill the hydro oil tank to the bottom of the oil level port and mine either doesn't have a oil level port or I cant find it. so how much oil do I put in it?

    If you have the tank with the 11/16" plug on top and no oil level check plug, then I would fill it to just below the threaded tube. Its about an inch or so from the top.

    The manual calls for " 4"-5" below the top of the oil fill".
    That's where we fill all ours to. If you use a flashlight, you'll see the fill tube actually extends into the tank quite a bit.
    The manuals readily avail online, just click on the Wright logo at the top of any page here and go to support.

    I would have to look, but there was a service bulletin on this a while back. You will want to make yourself a dipstick. They have all the levels listed in distance from the bottom of the tank. So dip the dipstick in and measure or put measurements on it.

    I wanna say the large frame (48/52/61) fixed deck machines were 6.75 inches measured from the bottom of the tank but I would have to check to make sure.

    We work on a fleet of 30 + Standers that are rode hard and put away wet. To tell ya the truth, I've yet to change the hydro oil / filter or any of 'em!
    The only time the oil or filter gets changed is if a pump or motor fails, which is very rare. Occasionally a blown hose or seal kit install, but not failures.

    I would be more concerned with changing the engine oil/filter and pulling the shroud and cleaning the cyl/head fins!

    thanks big fish. I understand that the hydro oils dont really need changing. I have worked for a company now for 18 years and that is the one thing I have never done with our walk behind ferris's. It is more of a precation thing for me. I got the thing used as my first peice of equipment for my own company I plan on starting in the spring so I did everything to it, carb cleaning, all filters, oils. It needs a new starter the one on it has a flat spot and new drive tires. Other then that the machine works good and I got it for a steal I think.....$1250. Good price or what?

    Hey, I'm not sayin' hydro oil/filters don't need to be changed, you should change it! Just that with the high cost of synth. oil, you can go a loong time between changes.
    You might wanna check the wheel motor mounts for cracking. They changed the design of the mounts in like '01 or so and incorporated a curved gusset plate on the bottom side to eliminate the stress cracking.

    Thanks for the heads up again. I will check it out when I take the tires off this winter to replace the rubber. One tire is completely bald so definitely needs to be done
