Hydraulic Shuttle Operation

PEJ5 · Mar 8, 2019

Here are a couple of rookie questions. I have a DK5010HS and I am curious how it 'really' works. If I press the clutch pedal, pick a gear, move the shuttle lever to forward and let out the clutch then clearly I am using the clutch and pressure plate to get the tractor moving.

If the shuttle is in neutral and I am in a gear with the clutch pedal already released, when I move the shuttle to forward, of course, the tractor starts moving. What is going on in the transmission? Does the HS simply engage and release the clutch for me or is there a separate engagement mechanism? A separate mechanism would certainly save wear and tear on the clutch and pressure plate. I suspect I am dreaming in color!
Oh, and while I am at it, does my tractor have front brakes or just rear. Now stop laughing! How embarrassing I know, but I bought my tractor privately and some things I simply do not know.

Have at it o'wise ones. I continue to learn much from this forum. Thanks!

I do not have a Kioti, but I can guarantee you that your tractor does NOT have front brakes.

Ixnay front tractor brakes.

Make sure you have 4-WD engaged going downhill so some rear brake retardation transfers to heavily weighted front tires.

"Re: Difference between Hydro Shuttle and Power Shuttle

The KIOTI Tractors, Hydro-Shuttle and Power Shuttle are 2 different transmissions. The Hydro-Shuttle is a mechanical clutch shuttle transmission based on 2 hydraulic clutch packs actuated by an electric-over-hydraulic solenoid valves that open and close the forward and reverse clutch packs. The Power Shuttle transmission uses a Power Shuttle Controller to monitor fluid pressure, ground speed, and temperature to control the electric-over-hydraulic shuttle valves and clutch packs. They operate in similar ways for shuttling the transmissions from forward to reverse, you can shuttle without using the clutch. The Power Shuttle transmission monitors the tractor conditions to control the shuttle. For example, in the hydro-shuttle, if you were travelling 5 mph and shuttled the transmission for forward to reverse, the hydraulic clutch packs would attempt to perform the shuttle, and possibly damage the clutch packs. With the Power Shuttle Transmission, if you shuttle at 5mph, the tractor senses the ground speed, slows the tractor down to a safe shuttle speed, then shuttles the transmission. The hydro-shuttle transmission has a mechanical clutch pedal, the power shuttle has the electric-over-hydraulic clutch."

I don't have a Kioti so I haven't looked into their clutches;
I do know that most all Power Shuttle tractors do not have a conventional dry clutch,
instead they have a separate multi-disk wet clutch for reverse and forward.
The "clutch" pedal is simply a rheostat that the clutch pack control reads a voltage signal from.

If you can find a parts breakdown for your tractor you can see what it uses.

Thanks for finding this answer. I guess my search of previous discussions was not detailed enough. Mine is not the power shuttle, but the more basic hydraulic shuttle - I have to be stopped or slightly coasting in the correct direction to engage it.
As for the transmission, in the description above it almost sounds like the hydraulic clutch(s) is/are separate from the pedal clutch mechanism.

That is how our L3830 is setup. There is a standard dry disc clutch for the clutch pedal, then the shuttle and the gear selectors have a separate wet clutch that the transmission computer engages and disengages.

Almost any tractor has brake's on the front wheels, what happens in some models with electric on of 4wd when the brake pedal is pressed the 4wd turn on automatically and then the tractor brake's in the 4 wheels
