Gravely Zero Turn Hydraulic Service DIY Made Easy, Includes Replacing the filters.

[@getit9066]

Open the fill plugs on the side near the top of each hydrostatic unit. Makes filling from the reservoir much quicker. There’s even a vent bolt on the very top of the units that works too.

[@RaleysSmallEngines]

Yes, you are correct my friend. Thanks so much for watching and commenting.

@Get It? thanks so much, that means a lot to us.

[@5star141]

That was the best tip ever !!!! I'm surprised that this guy in the video never even mentioned that or showed us video would have been 110% complete if it was for that mention of the ear plug on the top you have to remove the tires to do so to make it easier!

[@paulc8581]

Glad I watched this video . I'm about to do my dad's mower .

[@beavercreekdesign]

Thanks for taking the time to video. There are 2 allen head screws at the top inside of each transmission housing that do not look like plugs but you can loosen them to bleed air out transmission case. It will let oil in quicker. I just happen to see them on the parts list otherwise I wouldn't have known they were not housing screws.

[@AMinorCaseOfBlues]

Thanks bud! Exactly what I wanted to see. Thanks for taking the time to put it out there!

[@RyanTX254]

Thanks for the video!, just did a chinese carb part swap, air filter, and oil + battery (added some LED lights to the light kit to boot)... 37x hours on mine I got from my father and I dont think he ever did the Hydra's on it (still runs like a champ)

[@PAPSROYALAPIARY]

Thanks a lot, you just saved me a lot of headache on changing that hydro belt, mine just snapped and have to replace it, its already on order but had to figure how to make my life easy replacing it, that's where you came in, lol, your info is gold for me, probably do the hydro oil too, I got about 200hrs on it, never done the oil, worked great so far for my personal needs around the house. Again, thank you very much for taking the time to video this work, you and your wife. Dan

[@KarateSensei71]

Excellent video, I totally underestimated the time and difficulty of doing this. Your video was much appreciated. It took all I had to get the original factory filters off! Dang things were on so tight I destroyed them taking them off using filter pliers. The reservoir fill method took me the better part of two days for the air to purge even after trying the hydro cycling. I do believe next time I will pull the top plugs to purge air.

[@RaleysSmallEngines]

Glad you got it done my friend

I bought my zero turn second hand and while changing the oil I found the drive belt to broken in several places with big pieces of the belt gone. Only thing holding it together was the cords. Not to bad replacing it but I did remove the the old one so I knew how to put the new one on.

[@RaleysSmallEngines]

Awesome, great job my friend

[@Randyvance]

Isn't there a small screw/plug to remove in the transmission to bleed the air and speed the acceptance of oil into the system?

[@RaleysSmallEngines]

Thank you for subscribing. It would be best to get an OEM hose from a local Gravely dealer. Another option is to look it up on parts tree they should have an OEM to fit your machine. You will need your model number and serial number to look it up on parts tree.

[@edhall8911]

Just changed the hydro oil and filter on one. Supposed to hold over 4 quarts. When I put new filter and added oil it only took about a quart. How do I get all the old oil out?

[@zedcartwright3037]

I acquired an older Gravely ZT XL 42" model 915160. The owner's booklet says use 20W50 motor oil with an SL API rating for the steering fluid. Is this the same as the 20W50 transmission fluid that you are using? I sat the mower up a couple of months and when I used it again one side of the steering was a little off and it squealed some like it was too low of fluid. Want to change it but I am 73 years old and it is in the high 90's here near New Orleans and humidity will soak you within 5 minutes. Having no garage, it is hell working on it outside. Hoping to add some fluid and bleed it until late fall when weather cools down and then do a complete fluid change.

[@RaleysSmallEngines]

I understand the heat and humidity, we are in SC. Go to the parts store and get a quart of Mobile 1 full synthetic 20w50 motor oil. That will get you by until fall when you can change it.

[@zedcartwright3037]

@@RaleysSmallEngines Thanks. I will do that. The side that was weak and making a little noise was below the cold level line at the very bottom of the reservoir. Should remedy the problem for now adding some fluid and keeping it checked. My neighbor thought the motor was burning oil because it was smoking bad when he first cranked it up. He bought a new one. He gave this one to me. The governor shaft seal was mushy and was leaking oil onto the exhaust between mows causing the smoke. Replaced the seal and this Kawasaki Engine runs like new. The deck belt broke a couple months ago. I ordered a new one and used my MTD tractor mower until I got around to changing the belt. Guess it may have a slow leak on the left side.

[@jimmyclark]

What year is this mower? I have a zt hd52 that looks just like it but I don't know the year. Also how do you reset the change oil message on the hour meter?

[@coachliu32]

@raley How often are you supposed to change the filter and fluid?

[@Mrs.T-bone]

Well there are a lot of factors to consider. But for the typical homeowner, once a season should be good or when the oil looks dirty. For a commercial user it would be sooner because they are using the machine everyday.

[@bigjoe2458]

I have had my Toro 13 years and I have never changed the Hydraulic fluid. I never knew I was supposed to.

[@josephconsolini6342]

takes so long to have the fluid go down. Isnt there a release for the air bubbles

[@DAS-Videos]

That is what I am looking for on YT. I have the same mower and my instructions say remove the drain plug, and when filling, wait until oil appears at the drain plug. I changed my hydro fluid a few years ago without removing the drain plug and it took about 12 hours for the fluid to get from the fill tank to the hydros. I don't want to wait 12 hours this time :-)

[@TheRustyRooster]

Awesome video there T-Bone well done. Nice tunes your playing I might still one for my next video 🤣🤣

Man....so I mowed my lawn and decided to overhaul everything since I bought this second hand from my neighbors estate. I installed all new fuel hoses, new pt switch, new ignition, new carb, new spark plug and ignition module, new air/gas filter. Went to mow the lawn and the right hand control is no longer doing a thing. It did sit on a slight incline but had worked like a charm before the overhaul. It's an 08 gravely zt1740 and I see no hydraulic reservoir but instead...2 little caps on a small hose on top of both transmissions. I'm totally mechanically minded but I can't find maintenance manuals online to figure this one out. Any thoughts?

I expect this mower will last several seasons with decent care. kzbin.infoUgkx1VWTrayKBdCKAjzAcZ_Eg4dhHTae3LkN also recommend Also, I ran across the problem with it not starting the 2nd time I used it. There is a safety switch which is pushed in by the chute or mulching piece being attached to the deck. I took the cover off and it wouldn't start. Put it back on, no problem. It takes only a minute with 2 easily accessible wingnuts and no tools. This mower starts up first crank each time and it is a joy to use. It also mows in reverse by putting the key to the reverse area after starting and pushing in the triangular button. It will stay in reverse mode until you turn it off. All in all, for my homeowner needs, I really like this mower-and at 70 bucks a cut here in Miami, it's already more than 1/3 paid for itself in a month.
