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.

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.

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)

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 the hydro fluid be changed on a mz magnum bad boy

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

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

Not a blade of grass on the mower...pristine garage.... fancy lift...........love it.....lol

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

Can you make a video without exterior expansion tanks?

Sir great video, what kind of hydro oil do you recommend synthetic or conventional oil and where can I get that adapter plug that goes into hydros, Thks

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

Hydrogear always leaking

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

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

I want to know where I can buy one of those lawn mower lifts

Can I just fill the system from the expansion tanks?

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

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

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 !!!!

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"...

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?
