Changing the hydro oil on your John Deere Commercial Ztrak. Warning signs to look for.

In this video I go go over how to change the oil in the hydraulic pumps on the John Deere Commercial Ztrak mowers.
This mower was a Z915B. The customer said the left hydro was loosing power while cutting.
After doing a test run of the unit I confirmed the issue which side was having the issue.
After seeing the condition of the oil and the amount of debris in the left side hydro's filter I figured a flush of the system and new oil and filters may solve the issue.

Bravo! I have to tackle this now. Just ordered to fluid and filters. A long way from anywhere in rural Montana and can’t be without my mower in the spring. My left side transmission is always covered in dirt so I suspect there is a leak somewhere maybe I can find at the same time. Grateful for your video which gives me the confidence to approach this.

Hola, una pregunta, el tractorcito john Deere x355R recidencial también se le cambia el aceite de transmisión y el filtro? Muchas gracias. Ya me inscribí también

@p51mustang31 18 күн бұрын

Great video! I have a JD Z930R zero turn mower and in addition to these transmission filters, it also has a black filter mounted sideways near the mower deck. It appears to be some other kind of hydraulic fluid filter. Do you know what this is and should I also change it when I am changing the fluid and filters for the transmission?

Question, My 2017 Z930m and I can’t get it to steer straight. It veers to left . That screw at bottom left of seat does nothing. Any recommendations? When cutting full speed on low lawns, I’m always depending one lever some ti keep going straight . The adjustment screw does not do the fix of correcting the steer.

@Mechanical_Mind Жыл бұрын

The bolt on the left is just to help get the hydros in synchronization. There is another adjust ment screw on each hydro lever. You will need to remove the tire/ wheel to access it. It takes a allen wench to adjust it. If one of the hydros ia getting weaker as it gets hot Id recommend changing the oil and filters asap.

@johnpolishak Жыл бұрын

@@Mechanical_Mind Thank you , machine only has 225 hours on it. The veer left happens cold or hot. I bought it used with 167 this April . Guy only used 35 hrs / yr. I will change the oil and filter before 1st 2023 use, but I know that that is not it. I think it just needs a slight adjustment to make mower go straight and not veer left when both levers are push all the way. Your video on changing the transmission oil is excellent. Very detailed. You make great videos.

Question is why do Z900R’s go 12mph and Z900M ‘s only do 10mph?Both have the same hydro gears so why do Z900R’s do 12mph and Z900M’s do only 10mph?

@Mechanical_Mind Жыл бұрын

@@johnpolishakI made this video a few weeks ago kzfaq.info/get/bejne/pMBoZLBqmcW2hWw.html but there is that additional adjustment on each hydro you can try to adjust also. I often see machines come in that have water mixed in the oil and that can cause one side to slip more than the other side.

Great video! Are the outside seals serviceable to replace?

@Mechanical_Mind Жыл бұрын

Hi Scott, yes sir, all the seals can be replaced. The axle shaft seals are now much harder to replace. The hub and axle shafts used to be two pieces. About a year or so they made the hub and axle shaft one piece. So now on later models to replace that axle shaft seal you will have to completely remove the hydro and split it apart (upside down so parts to fall out everywhere) and the axle shaft removed to install a new seal. The most common reason they start leaking is from string/ rope/ twine/ wire get wrapped up around the axle and start getting into the seal.

@@Mechanical_Mind awesome thank you. This is a 935m that I’m going to look at tomorrow. Friend of mine clued me in that one of the pumps has a slow leak. So at the cost of $2500 for that whole assembly, it’s nice to know that they can be re sealed

@Mechanical_Mind Жыл бұрын

@@sgrasmick82 the most common leak is from the top shaft seal under the drive belt sheave/pulley. There is also a rubber plug that cracks from dry rotting. Its also on the top of the hydro and under that drive belt sheave. Change them both while you have the hydro out. That top seal also leaks from string and stuff getting wrapped up underneath that drive belt sheave. In this video I show how to remove the hydro. Its easy. kzfaq.info/get/bejne/fLWKmsWhxLWdlKM.html

Im guessing they either left the fill cap off or maybe the some got in through the axle shaft seal. Stuff will get wrapped around those seal and ruin them. I see so many weird thing with customers mowers. Commerical guys often slide off into ponds and complelty flood their mowers. Then they bring them in and dont tell us that info. They just say "its not starting" 🙄

@my95buick 10 ай бұрын

So what happens to the oil in the reservoir?

@Mechanical_Mind 10 ай бұрын

As the oil is drained out of the transmission the oil in the reservoir drains down into and out through the transmission being drained. If you only drain one transmission the reservoir tank will also drain out fully but the other transmisson and it's hose/tube to the reservoir tank will be full of oil.

I'm not sure what weight oil the JD HY- Gard oil is. I know other commercial JD mowers like the standers use 15w-40 motor oil for thier hydro systems. As far as the Ztracks I'd only recommend using the HY-Gard oil recommend.
