I'm the happy owner of a 2022 ZT Elite, just coming up to 1 year/50 hours so ready to do the service and noticed that my mower has no hydraulic fluid reservoirs. Is there a how-to video or sheet for changing the oil and purging the system for my rig?

[billywhittaker]

Thanks for the video. I am going to change fluid in my ZT Elite soon and it is nice to be able to actually "see" it done. I am really enjoying the mower. Thanks again !

My 2021 Maverick with the ZT3200's is ready for service. Mine does not have expansion tanks like any other diy video on here. Instead mine has a vent port next to the fill plug. Do you or can you make a video on how to service one of these? I know this is an old video

[berniesbend]

2023 Maverick has no expansion tank. It would be nice to see a video on how to service the 3200 Hydro-Gear 10cc Integrated Transaxle.

The manual that came with my zt elite says in one place to do an initial hydro service at 50 hours and in another place do the initial hydro service at 75-100 hours.

Great Video. Good closeup of all the particular screws n ports to look for. Need a video explaining how to equal both drive bars. Ive been looking for a good Bad Boy video expaining that. Look for ward to that. Thanks.

Just purchased a 2024 BB 60 ZT there isn't a reservoir on this model and 2 caps over the axle which one is the fill/check?

[Badboymowerpartsonline]

That is correct. There is no need to check the levels as you go because you have to get the system filled to the "Cold Fill Line" on the tanks. Through the process of getting the level to the port plug then filling to the expansion tank, effectively you are "checking" the levels. Just make sure to do the purge process. Great question!

I also have a 2022 ZT Elite 54 with no expansion tanks so I'm not sure where the fill port is. I found a schematic diagram of the transaxle online (not in my owner's manual) that showed the location of the fill port, but when I took a look at mine, there are 2 plugs in that location. I don't know which one to fill. I called the dealer where I bought the mower, and the mechanic had no idea that there are mowers without expansion tanks. It wouldn't make sense to take it there. Please answer the question on how to fill the transaxle with no expansion tanks. I'm coming up on 100 hours!

[Badboymowerpartsonline]

The expansion tank is just an overflow. That is why the fill to line is right on the bottom of the tank. The potential air bubbles in the system are tiny so purging the air will not cause a significant drop in fluid levels. If you have filled to the tank then the fluid in the tank and hydraulic hose going to the transaxle has plenty of leftover/reserve fluid to ensure the trans is full during and after the purge process.

I got my bad boy from my neighbor and have not been able to mow with it yet due to the poor condition from neglect. The mower looks like a very well built machine. My last step was to replace the busted hydro tanks and do a fluid change. Pulling the filters revealed water contamination my question is how do I clean and flush the system? Both motor seem to still operate at least driving from the field to the shop around 100 yards.

[redbluerc]

My manual says to use 20w50 motor oil in the trans on both sides....both of my brothers Maverick mowers is same way

[Jacoby]

What is the process of i have internal expansion tanks in my 3100s?

[jackiepratt]

you do not mention checking the fluid level during this operation when purging the air. is that because it is unnecessary? Thanks for the video.

[whitefreeman]

are there any videos of servicing the magnum models

[kevinheatherly]

What can I use to top off my hydraulic cylinder on my zt elite

[rellw.gamblin]

This is a very easy to follow, even if you're 85 he's old, Tks.

[EluderRacing]

I have a bad boy mower and it just started bucking or severely jerking on the right side hydro any idea what that might be or if this might fix that issue?

[shortribslongbow]

Where are the newest videos for 2024 on this procedures?

[WrenchAddiction]

I ordered your kit and received just 1gallon of oil. Why wouldn’t you include 2 gallons? I received 2 filters...why not enough oil??
