Ken lives close to me, stopped in and picked up some hooks and parts in person and have had shipped a couple times. Great products, works with local vendors and better pricing than box stores

Tim and Ken, what an excellent explanation and illustration of a typical hydraulic system. This is a great “go-to” video that answers a lot of basic questions about tractor hydraulics. Blessings to all!

Liked the explanation of the power beyound.

This is how a gear pump works in a nutshell. As the gears are turning on the suction side a tooth is pulling out of a pocket between teeth and causes a small void and draws a small amount of vacuum. 14.7psi of atmospheric pressure pushes the fluid into that void via the breather on the reservoir. The fluid is carried around the gears and on the pressure side a tooth is going into a pocket between two teeth and this creates flow. Pressure is a product of resistance to flow.

[coypatton]

One thing I have heard from way to many people is statements that resemble ‘my hydraulics have no flow/pressure until I operate a valve’.
Ken and you addressed this on the flow side quite well. Less so with how pressure works in the system.
Now I realize that typical operation stays under that relief valve pressure, I also realize there are mays to increase the pressure in the system up to that relief valve setting. You addressed this as well in the deadhead examples and the overloaded examples. There are others as well.
Bottom line without pressure (however not necessarily max pressure) there is no flow. But as Ken and you discussed, there can be pressure without flow (deadhead) until the relief valve activates and flow (not full volume) is restored.

Good video explaining the way hydraulics work! And nice to see a local guy (Ken) on your channel!

[igpoobah]

This video got me over the hump of understanding how this works. Thank you!

[stevestock]

Came across this vid today. Great knowledgeable guest on fluid hydraulics. Thank you for your presentation.

[kenlitherland]

Excellent discussion on the tractor hydraulics. A lesson for everyone.

Great Video Tim 👍 You may want to get Ken to talk about been Safe while working around these High Pressure Hoses. The High Pressure Hydraulic Hoses can hurt you bad if they get a hole in them while under pressure

I always knew how hydraulics worked but I wasn't exactly sure where to put the pressure relief loop. Now that y'all talk about it it makes perfect sense. This will help me figure out how to put a small hydraulic system on a riding lawn mower. I want to build my own implements rototiller, log splitter, auger etc.
Although you talked about the loop always being on. I'm going to be able to disengage the pump to prevent bulging down my engine when I'm not using the hydraulics.

I want to make sure I got the explanation correct. I have watched a few of your videos. With the summit valves I just need to hook up the valve to the output of the backhoe and then the other side of the valve to where the backhoe originally connected.

This is great stuff, very informative and useful for a student like myself going through agricultural mechanic training. I'll be watching your content regularly, thanks for the uploads!

[GPOutdoors]

Good morning Tim and Ken. Very very helpful episode - thanks! And thanks for taking the time to edit in the pictures as you spoke to help me understand the information. Tim - Thanks - excellent content. Ken, let me know when you set up a distributor for Canada! Cheers - all the best guys!

[jimpalmer]

Thanks for presenting this video. Great Information.

[maryriser]

Thanks for explaining to me how this works. I was told to keep my mini excavator on high because of the pump now I understand why

[HeavyIronAcres]

As others have said the power beyond explanation was good. Simplified it in my mind. Thanks!

[mrgoodwrench]

Great video guys. Simply explained and to the point. Very informative.

[f.davidbush]

Could not wait to watch this. Kenny is a great asset to GTT .

[DriverDean]

Thx for posting Tractor Tim! Very helpful...
