Can it be done without removing the transmission?? Watch and find out. Reference my other videos below to do this method right :)

My 42 inch cut Hustler Raptor has the sealed Hydro-Gear. I bought it new in 2014. It has not yet given up. 12 years and “if it ain’t broke, don’t fix it,” is where I am at this point. It has mowed my yard, neighbors’ and I have pulled an aerator on my yard with it. If the hydros fail tomorrow, well, I have been wanting a more comfortable anyway.

where can you put a drainplug on this particular type of unit ?

@hosslane320 1 month ago

Does anybody know if the mfg. has anti splash barriers inside the case to make harder to drain with even with tapped drain plug added ? I appreciate you young sir

Years ago I used to take a drill and drill a hole up through the bottom of the transmission while it's on the zero turn.

A drain the fluid out put in a self-tapping screw with a seal I did that for years.

The question comes down to what area would you drill the hole in
That's the lowest part of the transmission so you get all the fluid out maybe you could work on that idea I did it for years but I did not know if I was at the exact bottom

Same as an auto trans

Question, has anyone done a direct comparison on the nonserviceable transmission with change the oil as you describe vs adding a drain plug and then change the oil. Is there a life expectancy difference. Im assuming adding a drain plug would make it easier to change fluid as allow the heavier contaminants to leave the cavity more efficiently.

Tell him thanks for that information ! I love 69 also the 69 ford truck the 69 ford mustang. One question how much fluid is supposed to be in them . I have the 2023 Toro zero turn . And the right side sounds like it’s low from beginning. I have 125 hours on it .

Using just the pump out method repeatedly might be good enough for some (especially in terms of saving on extra effort to completely drain the unit). After the first pump out the oil will be 67% dirty, 45% dirty after the second pump out and replace, 30% dirty after the third pump out and replace and 20% dirty (80% clean) after the 4th pump out and replace and almost 90% clean after the 5th pump out and fill. Costs extra oil (not too much) and little extra effort to get the oil perhaps clean enough to keep the hydraulic system healthy.

How much of the goo stuck on the gears ⚙️ on the way out of the top when you turn them upside down. I’m glad mine have fillers.

Try compress air , than lose bleeder tube let it out that way! It takes total 1.68 qt

I heard you can drill a hole in the bottom, tap it and use a bolt plug with an o-ring. The oil coming out will flush out the drillings and tappings.

You need to use the VENT as the writer said 🙄

@danielhanawalt4998 2 months ago

Hard to imagine why those didn't come with drain plugs. I'm no mechanic but it makes sense fluids need changing periodically. Like your cars oil.

You could have tilted the drive to allow a lot more to be suctioned out with the black tubing you used.

It's not a lot different than the tilt and drip method but it has to be more satisfying to draw it out of there.

The drill, tap, drain, and plug method is clearly best.

A few years ago, Hydro-Gear announced they were going to add drain plugs to the EZT hydros. Instead, they ended up only doing it to certain serial numbers. They must've got pushback from vendors to not do it. Anyhow, if you've removed the units, go ahead and split the case. You can clean both magnets and drill tap drain holes. The casting bosses are already there on all their units. They sell 8mm and 100mm plug kits. It's not that much work. RTV the case back. They also sell rebuild kits. It's not difficult. Just have a clean bench and be mindful of things.

what about drilling a tapping a drain hole in the bottom and letting nature take it's course draining the
unit .. ?

I got just over a quart from trans using same style pump but a 1/4" hose inserted into trans, with the smaller diameter hose you can get down deeper in sump

Check the vent, hydro gear ships the units to various manuf. filled. so they dont leak in shipping they plug the vents. In time the seals blow out of the units. By the time the warranty runs out its always the customers fault!!!!!!
