power shuttle ?

spitter · Jun 3, 2017

I'm interested in buying a power shuttle transmission but somethings I ain't to shure about. When u put it in gear ie. tractor running shuttle lever forward or reverse does the tractor start moving or u have to step on foot throttle to move ? Being my property has some very tight places I need to get into and I don't like the idea of the tractor moving as soon as u shuttle.Most of my work is loader and fork oriented. I am only thinking about a power shuttle because I want a large cut older 1995 to 2005 vintage .No or limited electronics.I work on everything my self so looking ease of maintaince. We have a gradeall telehandler at work that I drive a lot and I realy like it. No clutch. Start it up electric p brake shuttle into f or r step on foot throttle and start moving.Has a regular size foot throttle. Most P S trans or R I see have a small little button like foot throttle how does that work ? I really like the TC NH line TC 55da but if u shuttle into drive and the tractor starts moving automatically I see nothing but problems when moving in tight areas .Kubota has a hydro but I absoulitly hate the treddle peddle on them. A J D 4720 hydro will work but they seem to run about 5 to 10 thousand over a tc55da.Any thoughts about a tractor that might fit the bill would be greatly appreciated.

Power shuttle transmissions move as soon as you shift away from neutral. There is a clutch pedal for close, precise movements.

Exceptions to this would be tractors with torque converters ahead of the power shuttle clutch packs, but this configuration is mostly limited to construction equipment.

What size cut are you looking at? Are you moving up in size over what you have???
You may be better looking at a hydro, or industrial tractor to get the type of gearbox you want.

Thanks 4 reply guess i'm stuck with finding a hydro that has no treddle peddle and that doesn't cost a arm and a leg.:confused3:

I'm not familiar with how the ag version power shuttles work but I will be looking for a 50+ HP something in the future. Couldn't you just hold the brake when you put in forward or reverse?

On a side note my little JD855 hydro has a tendency to creep if I don't use the brake. My industrial power shuttle has no clutch and the brakes don't work so I have to be very careful and shift to the opposite direction to keep from hitting anything if I am close to a structure. (I need to get those fixed)

If you hold the brake with the tractor in gear, you will steal the tractor. If the transmission is in gear the tractor must be moving, or not running.

To the OP, spend a couple hours with the treadle pedal if you can. It's really not a big deal, especially if you have cruise control. I wouldn't want anything other than HST for close maneuvering, but that's just me.

Also note with a hydraulic shuttle in gear, engine off, there is nothing to keep the machine from rolling except the service brakes. Or flat land!

I'm not sure why it's so unappealing to feather a clutch pedal. Several million tractors have them.

My 6530 has the shuttle shift. To crank the shuttle has to be in N. Once tractor is running, regardless of what gear is selected, you depress the clutch and shift the shuttle to F or R. No movement occurs till you let the clutch out just as if you had a regular gear tranny with no shuttle, put the shifter in a gear and let the clutch out to proceed with ground movement.

For shuttle work, you select what gear you want (for me out of a combination of 24 possibilities) and work the clutch and shuttle back and forth as fast as you can move the lever from up to down; silky smooth. If you want to interrupt any travel, just leave everything as is and depress the clutch like on a regular gear shift tranny.

PTO is independent, controlled by an electric switch selector. If you want to use "Live PTO" position on mine, the PTO is still independent, but you can cut it off and on by depressing the clutch, just like you can do with a regular "live" PTO tranny in a conventional sense like my Ford 3000. Makes post hole digging a dream.

Other thing the Branson has is PTO interrupt. If you choose to use this switch controlled option, there is an electric switch that can be used (in combination with the normal PTO lift lever, or used alone) that lifts and drops the PTO to pre-set positions. With this feature, if you choose it, you can have the PTO stop when the 3 pt is raised, dropping the 3 pt re-engages the PTO.

Just a few of the reasons the 6530 is in my corral.

hydraulic transmission = more precise control over speed.

the old ford 333c TLB (tractor loader backhoe),
--industrial tractor not an agriculture tractor.
--power reverser/shuttle (same speed forward and backwards)
--4 ranges (gears).
--1 clutch button on the shuttle lever by steering wheel,
--1 clutch button on the FEL joystick,
--1 clutch button on the range selector.
--1 foot throttle peddle.
--1 lever throttle (primarly for backhoe useage but can be set to hold throttle peddle to given spot)
--split brakes on opposite foot. of throttle peddle.

press shuttle clutch and flip to forward or reverse and release button. and it slam the tractor into opposite direction. generally you need to work the throttle peddle to slow down to near stop if not stopping to switch back and forth so you are not riding a bunking bronco throwing you forward and reverse and giving you whiplash. ((more so at higher MPH))

===========
HST (hydro static transmission)
--single peddle that rocks forward or backwards for forward/reverse, center = neutral
--some of them have 2 peddles 1 for reverse and 1 for forward

===========
hydraulic transmissions such as above. is not like a regular gear/manual shift tractor or truck. were if you load up the engine you can kill/stall the engine. instead a pressure relief valve kicks on in hydraulic transmissions, and you loose torque and speed.

for hydraulic transmissions you need to start in low range and work you way up through (experience) till you find capability of machine so you are not causing pressure relief valve inside transmission to open up on you.

an example. got a heavy load in FEL bucket, plus backhoe bucket. running on flat dirt lane. i can mash the peddle to the floor but not really go any were. as soon as i press say 1/2 way down and not all the way down, i suddenly pickup lots of speed and can maintain that speed. why?
less peddle down = most torque / less speed,
and when throttle all the way down = less torque and more speed.
the throttle peddle in this case is selecting the torque to speed ratio that works for load on the machine.
other words throttle peddle = infinite gear range selector between torque and speed.

hydraulic transmissions with infinite gear range doing, allows for "creeping up" 1/2" to 1" at a time slow speeds, to higher end say 15MPH to 25MPH the range/gear selector there to help adjust a bit more.

only when throttle peddle is completely up. and/or clutch is depressed, and/or gear select in neutral, is tractor in neutral per say and will not go any were.

"When u put it in gear i.e.. tractor running shuttle lever forward or reverse does the tractor start moving or u have to step on foot throttle to move ?"
I have a 75hp Kioti power shuttle, and have regularly used larger JD and NH tractors with power shuttle. All have a regular foot clutch as well as the shuttle lever. You can start them all in neutral, foot clutch in, and then select forward or reverse on the shuttle, choose a gear, and then use the foot clutch to start like any other tractor. Or, you can start the same way, let the foot clutch out in neutral, choose a gear, then use the shuttle lever to start moving - it does the work of letting the clutch out.
For close work (I do a lot of loader work, fork work, and stack round bales, all of which are up close and personal to shed walls, other vehicles, etc. After enough experience, I find that I use the shuttle shift lever for the larger movements, then when I get close to placing a bale or pallet, it's one hand on the wheel, left foot on the clutch pedal, right foot on the brake, and right hand on the FEL control joystick - no free hand for the shuttle lever, and I can feather the foot clutch to control movement, just flicking the shuttle lever back when it is time to reverse out.
Boggan mentions slamming things backwards and forwards, and that might be fine on a commercial loader - I don't have the experience to comment - but I have been warned by a number of people (including long time salesmen of this kind of agricultural tractor, and some very experienced mechanics who fix this kind of machine) and they all say that you should shuttle to neutral, let the tractor stop or almost stop, then shuttle to the opposite direction.
Personally, I have found that the power shuttle (where you don't NEED to use the foot clutch) is optimal for the kind of work I do, where the tractor has to have the fine control for the inside-the-shed jobs, as well as the ability to pull a plough all day when needed.
Note that there are two type of shuttle transmissions - the power type described above, and the just-a-shuttle type, which still needs you to put the clutch in for every change of direction.
I have been impressed by my Kioti, and wouldn't hesitate to recommend them as an option - they have HST, manual shuttles and power shuttles in many sizes. Worth thinking about. Good luck finding the right machine for you.

Wow wen't to work and got lots of replys. Thank u all

:thumbsup: Try to explain my perdicument better.I am looking a cut with the best loader capacity. Something like a koiti nx 65 .I use forks on my tractor most of the time. I have a tc29d with a treddle peddle and I abousoulty hate I.I have had both knees replaced , real bad foot problems and bad back.{go by the name of lucky].:laughing:I have a simplicity legacy with twin pedals and it works better 4 me.My property is 5 acres and has about 50 ft of rolling grade change.Pretty steep in some places. Also my kids 14 and 20 need to be able to run the tractor .They have been onequiptment all their life but u know kids when u put clutch brake shuttle in mix. that's y I was thinking of the lull in work trans it is pretty easy to operate and if there was a cut powershift like it. I don't like to buy anything Ican't fix my self.2008 seems to be the cut off for non pollution not overly electronic cut's.My tractor sleeps outside under a tarp so the less wires the less the mice have to eat.

A DX 65 would be nice but it's only shuttle. When looking 4 95 to 2008 Koiti Massey and Mihandra aare far and few in between. Does that leave me with a choice between a 4720 or a 110 tlb .Has anyone gone from a tc 45d to a jd 4720 or 110 tlb and is the loader that much stronger to justify the 5 to 10 thousand dollar price jump?Thank's again:drink:

Older hip joints or knees are a couple I can think of.

From reading this thread, hydro treadle pedals are worse. Many 'clutch' pedals on power shuttle transmissions control a button switch and potentiometer, and have a spring for artificial resistance. These typically require less effort than a dry clutch pressure plate.

You guys can pontificate all you want, operating tractors and machinery requires physical effort. If a person can't operate pedals they can't use brakes and probably shouldn't drive tractors that are unmodified for use by folks with physical challenges.

I agree that treadle pedals are not a great method of controlling a tractor. I prefer side by side pedals and so does my wife who has the above disabilities and gets along fine with side by side hydro pedals.

Why the elitist attitude?

I have both getting scheduled for replacement this summer and fall. I don't have any issues at all clutching my Workmaster shuttle shift with the bad left knee. The right hip gives me a fit getting on and off the tractor. Operation of the tractor for me is a non issue at this point. After surgery I hope to be able to get on and off the tractor pain free.

The side by side pedals on my little jd cause fatigue also. When I'm on it for any period of time and can I use the cruise control.

I don't think I would like the treadle.

Elitist, or simply a viewpoint other than yours?

I am currently demo'ing a Mahindra 6065 (unreleased demo tractor) with a PST transmission. You can shift from neutral to forward/reverse using the PST lever but it will jerk the tractor. It is best (and advised) to step on the clutch when changing gears and feather the clutch out to get a smooth takeoff.
