When trying to engage my pto (ford 3000) i get gear grinding and will not engage.
I had the motor ideling / transmission high - low in neut. / transmision in neut. / clutch in and clutch out. What do i need to do ?? Manual says "to start the pto, move lever sharply forward into fully engaged position". I'm afraid i'll shear some gears if i force it in.
Thanks --- bar bill

Something you can try. Engage PTO with the engine shut off, then start engine and see if PTO is rotating. Then try to disengage the PTO with engine running at idle and notices if it slips out easily. Then try to engage again with engine still running at idle. If you still get a grinding resistance, I'd say your clutch or bands need adjustment. Hope this helps.

I did as you said ---- engaged the pto and then started the engine. Snowblower / pto worked fine. I disengaged pto -- while in idle / while snowblower / pto was turning --- disengaged fine. I tried to re-engage then --- but got the grinding gears.
This is supposed to be "live" power. Doesn't that mean the pto runs (when engaged) if clutch is depressed or not ???
Thanks for hanging in there guys -- it's got me puzzeled.

If you have a "Live" PTO, then yes the clutch doesn't disengage it. My Belarus has same set up and is controlled by bands. I would say they need to be adjusted. Do you own the shop manual for this tractor? If not maybe a dealer would lone or photo copy theirs. If you aren't mechanically incline, hire someone to do it for you, or take to a shop. One more question, what rpm does your tractor idle at? If it's turned up too high you will get this grinding also.

Bill,

Couple of things:

1) With a live PTO, when you push your clutch all the way down, the PTO should stop.

You should be able engage the PTO lever without grinding, but mine often grinds a little bit - minor grind & "clunks" in - even with the engine idled as low as it will go. You can always turn the engine off to engage the PTO. But the PTO should stop when you push the clutch all the way down (safety feature - you must be able to stop the PTO).

2) Your clutch should have about 1-1/4" to 1-1/2" of free play - push it down with your hand till you feel resistance, and measure the amount of free play you have.

You probably need to make a minor clutch adjustment. You adjust the clutch by shortening the linkage where it attaches to the clutch fork arm. Loosen clevis locknut, remove cotter pin and clevis pin, and turn clevis.

Turn the clevis ONE TURN at a time and check results. Do not over-adjust the linkage, or it will shorten the life of your clutch.

My mistake Bill, sixbales is right about your PTO! My PTO has two settings. 1 "Independent"so it is not affected by the clutch. 2 "Synchronized ground drive" where clutch can disengage PTO movement. ( Used to power, towed trailer axles. ) BIG THANKS to you sixbales for catching that one!

I'm a little confused --- i'm thinking "live power" is the same as "independant power" --- just a different term --- but evidently it's not. I'd guess my 3000 is "independant power" cause that what the manual mentions --- "independant".
If that is the case --- and the clutch doesn't disengage the gears --- how do i engage pto with out the grinding ??
Surely it should engage with the engine running.

Bill I am not sure how your tractor is set up clutch wise. My PTO is engaged by a lever that you move quickly thus engaging or disengaging the PTO. Some, if not most tractors use a two stage clutch setup. With this type clutch you push half way down to stop power going to your wheels and fully depress to stop PTO movement. This is useful like when using a snow-blower in heavy deep snow. You can cut power to wheels but blower keeps going, until clutch depressed fully. My tractor is set up differently than that. Pushing my clutch fully, doesn't stop PTO power in "Independent" setting. To stop my PTO, I have to move the lever out of engagement. In regards to your question about PTO engagement, think about an outboard motor. There is no clutch lever to move before switching gears. This is how my tractor operates. Another thing you could try while engaging your PTO, is to have the tractor in gear and ease out on the clutch peddle till you feel strain coming on. Then at the same time quickly engaging the PTO lever.

I think my tractor is like yours with the outboard motor style pto engagement --- "independant".
I shall try your ideas and let ya know.
Thanks you guys, for all your input. With y'alls help, i'll get this d--- pto thing to working yet !!

I'd like to add a quote from my manual that makes me think as i do with my previous reply.
"on independant pto tractors, the shift lever is the only control used to engage the pto shaft. To start the pto, move the lever sharply forward into the fully engaged position".
If i do as you mentioned (bulldog) and try to engage while releasing the clutch to move forward --- that may slow the gears down enough to accept the engage / smoother. Again --- i'll give it a try.

I copied the following from tractordata.com. According to tractor data.com, a Ford 3000 can have a transmission PTO, a live PTO, or an independent PTO (with select-o-speed transmission). Here's their description of each of these:

There are three basic types of PTO control on a farm tractor:

Transmission

The simpliest, and earliest, form of PTO is the transmission PTO. The PTO shaft is directly connected to the tractor's transmission. The PTO is only working when the tractor's clutch is relased, so if you take the tractor out of gear while slowing down the PTO will stop working. This is a disadvantage in applications such as mowing.

An overrunning clutch is often needed with a transmission PTO. Without it, the driven equipment (such as mower blades) will put a force on the PTO shaft, and then the transmssion, due to inertia. The equipment will "drive" the tractor, and you will still move after using the tractor's transmission clutch. An overrunning clutch prevents this from happening by allowing the PTO shaft to freely spin in one direction. In more recent models, this is built into the tractor. In older tractors, it is an extra piece of equipment mounted on the PTO shaft.

Live (two-stage clutch)

A live PTO works with the use of a two-stage clutch. Pressing the clutch half-way will disengage the transmission while pressing it fully will disengage the transmission and the PTO. This allows the operator to slow down or change gears while the PTO is still operating.

Independent

An independent PTO means that the PTO shaft is controlled with a separate clutch. As with a live PTO, this allows for full control over the tractor while separately controlling the PTO. There are two major types of independent PTO; mechanical and hydraulic. A mechanical-independent PTO uses a separate on-off selector, in addition to the PTO control lever. Often the tractor must be stopped or off to change this selector position. A hydraulic-independent PTO uses a single selector.

BILL CROOK

Great info big _t --- thanks a bunch.
I have one question. You quoted "an independant pto ---- (with seleto-speed)". Does that mean that the independant pto was adapted --- "only" ---- with select-o-speed ??? My 3000 is manual trans and that would narrow it down to "live power" only ------ because it's not "transmission power".

Bill,

I got that from tractordata.com for a Ford 3000. Below is a copy of their stated PTO arrangements for a 3000:


Rear PTO: transmission (4-speed, 8-speed)

Live (over/under, optional on 8-speed)

Independent (Select-O-Speed)

Rear RPMs: 540

540/1000 (Select-O-Speed)

Tractordata is not always right, but they have a pretty high percentage of being right. My read on the above is that an independent PTO was available only with a select-o-speed transmission. Note that a select-o-speed can have both 540 and 1000 rpm PTO's.

My guess is that you have a live PTO with a clutch that's out of adjustment, or simply a bad two stage clutch clutch, which is a fairly common problem.

BILL CROOK

Your last line --- "maybe the 2-stage clutch gone bad" --- sounds like lots of $$$$$$$ !!!
And --- your probably right.
Thanks again --- i've got something to go on now anyways.

I've ordered up a shop manual for the 3000 -- maybe that will help me solve my pto problems. I do have another question though.
When i lift my snowblower (3 point) ----- when it gets to the top --- it jerks a little while holding it up. Is that normal ??
Bar bill

Big_T

I copied the following from troubleshooting hydraulic lift systems section of my shop manual:

EXCESSIVE CORRECTIONS (BOBBING OR "HICCUPS") IN RAISED OR TRANSPORT POSITION
Could be caused by:

1. Worn or damaged check valve ball or seat.
2. Selector valve worn or damaged.
3. Unload valve plug worn.
4. Lift cylinder safety valve damaged.
5. Faulty lift piston seals.
6. Control valve worn.
7. Damaged O-rings between lift cylinder and lift cover, or between lift cover and accessory cover.
8. Cracked or porous lift cylinder or lift cover castings.
9. Shall I go on?? Just kidding - that's it.

I think most people live with this phenomena until it becomes a more significant problem, i.e., the lift doesn't work satisfactorily.

BILL CROOK

I've ordered / recieved / read (pto sections) the ford 3000 owners and shop manuals. I now know a lot about the pto for my tractor. It is "live" power with a two stage clutch. With the clutch depressed 1/2 way --- stops the tractor / with the clutch depressed all the way --- stops the tractor and pto. Unless i missed it though, nothing was mentioned in either manual about how to adjust the clutch petal / linkage so as to stop pto. Gears to engage it or even if the clutch can be adjusted. So i still lack the info on what to do --- to the clutch (or whatever) ---- to stop the gears so as to let the pto lever engage without grinding them.
What say yee smart ones.

disngage the pto gears or even if it can be adjusted.

flyingace

I have the identical setup, so something about your description doesn't add up.
The PTO engagement lever goes back (towards the rear of the tractor) to engage
the PTO and forward to disengage. Maybe I misread something, but if you are trying
to jam it forward to engage it when it's already disengaged may explain why gears are thrashing around.

sixbales

Flyingace is correct - "The PTO engagement lever goes back (towards the rear of the tractor) to engage the PTO, and forward to disengage".

To adjust the clutch, look in your manual under CLUTCH - LINKAGE ADJUSTMENT.

BILL CROOK

WELL I STILL HAVE MY PTO PROBLEM. I HAVE ADJUSTED THE CLUTCH TO THE MAX AND FULLY DEPRESSED, IT STILL DOES NOT DISENGAGE. I EVEN TRIED USING A BAR ON THE SHAFT --- WITH THE CLUTCH DEPRESSED --- WITH THE PTO LEVER ENGAGED (PUSHED TO THE REAR) --- TO BREAK IT LOOSE --- WITH NO LUCK. EVIDENTLY THE PROBLEM IS INTERNAL. THE SHOP MANUAL IS WORTHLESS. IT SHOWS ALL THE INTERNAL PARTS -- BUT EXPLAINES NOTHING. NO TROUBLE SHOOTING SENERIOS ACCEPT -- "ADJUST CLUTCH". THERE IS A 6 in. ROUND INSPECTION PLATE JUST TO THE REAR OF THE PTO LEVER. COULD A MECHANIC FIND THE PROBLEM FROM THERE ?? IF SO WHAT WOULD HE LOOK FOR ?? OR --- ANY OTHER IDEAS ?? THIS BEING THE 1st --- MY YEAR IS NOT STARTING OUT VERY "HAPPY".
HOPE Y'ALLS IS,
BAR BILL
