Thanks for the video. Where can I purchase the hand pump and the fill fitting that screws into the fill hole?

Can you make a video without exterior expansion tanks?

Great info especially the bypass process.👍

Should always make sure you can get top port plug out before draining oil.

what size is the socket to remove oil filter cover?

Thank you So Much

Where is The Purge valve located at on the pump

THANK YOU...for this video. While I was unable to directly find ANY videos disclosing the hydrostatic drive bypass valve for a Snapper zero turn mower...i happened upon THIS video, which revealed a nearly identical hydrostatic transmission/ drive, AND ..."Huzzah..😄" the location/identification of that elusive bypass valve. Again..thanks so VERY much.

Would be worth including in the video, that "port plug', or otherwise "air bleed", can be located in other locations... After draining oil from my JD Z740R, both oil filters removed, it occurred that indeed there is an air bleed screw on the left drive, however there is a hose attached to this very port on the right drive... Wasted two hours trying to figure out what to do, when I thought this video showed full procedure, EXTREMELY frustrating and disappointing... Eventually figured, going left to right and back, checking what's different between both sides... Found that left one has a hose connected to the top, and air bleed where the video shows, while this is switched on the right drive, obviously just to annoy and confuse... Why NOT just use flexible hoses to connect to same ports on both sides, to make it intuitive, LOGIC, and EASY to service??? Surely an xtra hole through a steel plate, or 10cm of additional hose, and possibly a cable tie cost at manufacturing process, would not lead a top manufacturers to cut corners like that...? Would it...? "hopeless sigh" Whoever signed off that section of design must have been a true "genius"... doh! Once I found the air bleed is located at the top on the right drive, where hose is connected on the left, it's taken me another 30mins to realise there is an access port right beside the oil reservoir, to reach down with a socket approx a foot down (lucky I had all extensions required for the procedure) to finally get to this hidden screw... Not a word mentioned on any of my above findings in the user manual. Only reference was "diagram" mentioning there are two air bleeds on both sides, in resolution so low it could be really pointing ANYWHERE, and not showing at all, nowhere, how to access the air bleed... Extremely, extremely disappointing... Please note this comment comes from a professional who works long hours 7 days a week during mowing season, and downtime of this sort is simply way beyond word "frustrating"...

My Ferris z3x has these pumps but the vent port is an 11mm and it’s in a terrible location for a service item.. the bolt in this video was more like 3/4 so something must have changed.

My zero turn mower has twin ZT-2800 Hydro transaxles. I was wondering if you could add reservoir tanks on these units because they are not equipped with them currently? It seems like I have plenty of room to add them. Also what reservoir parts would you recommend if applicable? Thank you.

Can I just Jack the back end up to do this, or do I need to put the front on jack stands and then lift the back end as well?

Hi, does anyone own a Husqvarna PZ60? I'd like to request some quick guidance on that machine, since I'm trying to understand the Bypass valve ordeal, since the manual makes it extremely confusing. The explanation is very vague. Here are the couple of questions: 1. Is the Bypass Valve the same thing as the Pump Release valves? In other words, this zero turn lacks a rod that you can pull to quickly disengage the transmission. Instead I'm supposed to use a 5/8" wrench and move (counterclockwise?) the Pump Release valve on both pumps to be able to push the zero turn with my hands (neutral). If there's a separate Bypass Valve in the PZ60, can you please let me know where it is located - cause I cannot see anything that I pull back and hold (like the old tractors and other zero turns). 2. The manual says that each pump has 2 Pump Release valves and that I need to move the plastic fan on top to access them. Well, I've removed the plastic fan and I only spot 1 pump release valve per pump. I really appreciate your attention, and if you have feedback, I will gladly welcome it - as long as it's not the same information from the manual because that does not make sense. I'm including the webpage that has its manual under page 35: usermanual.wiki/Husqvarna/HusqvarnaPz6096661440103201306OwnerSManual.1645125581/html#pf5 Thanks!

I have a Husqvarna PZ29D and have tried purging about 15 times and still after 5 minutes it starts playing up. Any tips?

For those having a problem with this process here is a tip. If you have a machine that has a resivoir tank you still have to remove the 1/4" allen plug at the top of each axle so that the air bleeds out as it the axles fill. I forgot about these this round (they had dirt in the allen holes and I didn't see them on my inspection) and the oil did not fill one of the axles and it would not rotate on its own. After pulling the plugs keep refilling the resevoir as it drains down until oil comes out the ports. It takes a while and several top offs. Then plug them back up and top off and do the purge process.

Hydro gear purge

I have a ferris z3x with 14 hours on it, it started shrieking on the left Hydro. The longer you run it the louder it gets. I went through this procedure and it still does it what could be the problem?

On my 5400 the wheels turn under no load with the bypass open. Fluid was at the level specified on the manual and on reservoir tanks prior to this. Am I doing something wrong.

Hydrapac hp 21 pump

Yeah we sure needed a video on how to change the fluid on those pumps we've only been freaking changing out the oil on those pumps for freaking damn 20 years

Why does no one make a video for the internal expansion tank version?

Curious, what would the noise or resulting issues be if you ran your hydro fluid dry?

Best see if the the top port plug can be removed FIRST. If you drain the oil and discover the top plug seized, then you are screwed.

No sign of this fill plug on the zt2800. I think my reservoir hose goes in this plug.

I have a Scag Cheetah with the ZT5400s, I can remove the vent port plugs but it's a disaster every time I change fluid as I can never catch it just right, resulting in an overflow mess. You now include two threaded fittings and two short lengths of transparent hoses with each oil change kit..... I was hoping this video showed their purpose. It did not.

Hi Hydro-Gear, What oil would be best for protection and performance, 15w/50 full synthetic or regular 20w/50?

Do the bypass valves need to be torqued to a certain spec?

We will leave out the rate of torque for some strange reason.

What do you do if your mower doesnt have the reservoirs?

Can I just fill the system from the expansion tanks?

Can anyone tell me at how many hours should I do the first hydro oil change for a stander b Wright ???? I’m going crazy. It seems like EVERYBODY has a different opinion as to when I should make the first change. I’ve gotten answers from the first 75 hours all the way to 400 hours. It’s insane !!!!

Are the by pass valves suppose to move back and fourth when they’re closed? I have a wright stander b and they move around. I zip tied them down so they wouldn’t move but than my right hydro started giving problems. (Loss of power) so I removed the zip tieds. I’m praying it was just air pressure trapped because I zíped tied them down

Hello ! Can I have a solution for the replacement of oil as a European customer in the same way as any of your customers ?

Hi, Great video ! And the technique seems easy to understand even for a European handyman ! Where should we buy your HydroGear 20w50 brand oil in Europe ? Your exclusive Bibus France dealer seems not to be able to sell your reference kit 72750 compatible with the 2 hydrostatic axles ZT 3100 of my Toro Timecutter HD. Regards, Greg (French customers)

I gave it a thumbs down because they don't respond to questions/comments. Otherwise good info.

I have the exact mower you're working on. It would have been nice of you to mention that you can't easily access (unless you have smurf hands) the port vent plug without removing the transaxles. It would literally add 4 seconds to your video, making it an even 3 minutes, but saving me a lot of aggravation. I see a half dozen locations you could have placed the vent plug to make it much more accessible without removing each transaxle. Good grief.

You don't engage the pto while changing the fluids? You're kidding me.

My mower has a loud whine sound and won’t turn. This happens as soon as it warms up

Great video 👌

I have a old 3 wheel skag I changed the oil cooler but filled it before installing plus put a new hydraulic belt on it now start the motor and the hydraulic pump is barely moving and there is no bypass valve on this 1996 mower which is a 3 wheel skag what could I do to repair??

Hydrogear always leaking

I have the older Bobcat with the older style pumps. Do you guys have a video for oil change in those?

How often should the fluid and filter be changed? Please don't tell me to look at a manual!

You think you could have put the vent port plug in more accessible spot? Impossible to get out where it is located on the Farris z3x. Just saying.

Can the hydro fluid be changed on a mz magnum bad boy

It's sooo little 😧

I had to do the axle conversion on my toro time cutter z420 Im putting in new oil. I looked in owners manual and in the parts manual for the type weight etc for the type and quantity of fluid. I have one axle in and im ready to seal the case. I dont want to set it aside until I get the fluid in it incase it locks up or something. The action is very smooth so im pleased with the replacement.

After recently changing oil and filters on two ZT-3100s, I was trying to purge the system. Having the drive wheels off the ground and bypass valve open, of of the wheels still rotated. Any suggestions?
