How does a Hydrostatic pump work? 

While that part is amazing enough in itself, what I find more amazing is the fact that someone came up with that idea.

And those tolerances are why you change your transmission/hydraulic fluid regularly, and with the right fluid for your *specific* machine!

I taught hydraulics in a VoTec in Oklahoma for 5 years and loved it. Before I taught worked as a hydraulic technician and put in a few hours in the field working on Sundstrand pumps and motors. Nothing like fluid power. 👍🏻

Professor Neill!!!! Great "class"! Thank you!👍

The power of hydraulics always impressed me , interesting to see inner workings.

Back in 1981 I had an old Cub Cadet hydrostatic 12hp front end loader yard tractor. When cold, it was good, but lost function as it warmed up. I knew nothing about troubleshooting it, and knew it would be expensive if I took it to a shop. 31 years later I bought my BX25 and have accumulated 3237 hours. Love it. But I only learned about HST pump and motor when I bought a hydrostatic drive lawn tractor that did not function. The previous owner had it repaired, but when reassembled, a part was installed incorrectly. I fixed it and use it as my acreage runabout, towing a sweeper and various trailers. Love hydrostatic.

I’ve used hydrostat transmissions for years, but never saw the inside of one. (Probably a good thing ;-) Thanks for sharing this.

Thanks for doing this one Neil! I think this was for my request a few weeks back - much appreciated!

Thanks for the education, it's just amazing how they develop new ideas and technologies.

Another great and fun video Neil! Thanks

Great video Neil thanks

Flashbacks from when I rebuilt aircraft hydraulic pumps and other hydraulic systems.

Nice explanation. Thank you

The design was by vickers of england many years ago

Amazing

Thank you for sharing

I've often wondered, thanks!

Hah. I was like 'oh like a helicopter' and then you pull out the swashplate.

Very cool.

Hydro-drive power units are king for applications such a landscaping. The ability to feather the machine travel speed instantly is much safer than gear drive and loader work is also more efficient. Gear drive has its place though, especially for field work.

The only thing I'm not happy about my BX-23S is the hydrostatic transmission.

Glad I got a gear drive Kubota.

Looks expensive. They have play-boards for toddlers that show how gears work, so I guess I’ll stick with my 35 year old gear grinder Ford tractor. I understand it.

I was somewhat shocked when I saw that Mike Morgan is leaving the fold. And going with a different Manufacture.🙄.

Now if we could just fix the kubota whine… 🫤
