PTOs on the TEA20

Hi All

Have been using the teat20 for about a month now.

today i had the slasher on so used the pto for the first time.

It seems to get stuck in gear and you need to wait for the shaft to stop spinning before you can get it into gear, also sometimes it leaps forward when you select a gear? I suppose an Over run clutxh would fix this?

Is it normal on these to have to let the pto stop before getting a gear, or is it a clutch adjsutement needed?

Used a fergy buck, good with a little bit of muscle to tip the bucket, so keeps you fit.

Been puting the blade to good use and playing arounf with the top link for different cutting grading.

PS. Is it OK to raise the slasher with the blades turning, seems bloody unsafe but only way to do it?

Cheers
 
An over run clutch is a real necessity , unless you want to end up in a dam or barrelling through a fence . The big heavy blade of the slasher acts as a flywheel and turns the gearbox directly even if you have the clutch pushed in . Bloody scary ! :shock:
Only way to raise it is to have the pto running , but if you have a position control or some chains fitted to hold it's height this shouldn't be necessary.

Yes, and I have some good news for you .... from what you describe, your TEA20 hydraulics and PTO are functioning exactly as designed and intended.

Go buy your self an Over Run Clutch (ORC), around $100, or you will end up in a tree/through a fence/running into something/running over someone and possibly doing yourself some injury.

Yee, as your strine mates already said, this is the way they work. I know the feeling of raising the turning blade, but with a single clutch, them's the choices. To idle at the slowest rpm and wait a minute for things to settle down is increasing the odds of the pto going or coming out of gear without gnashing the teeth yet still remain running.
To climb off and unhook the shaft can get old after awhile. But best for the ride home to the barn or down the road aways.
It is always safest to think 20 yards ahead, even with the overrunning clutch, it's a contest of who's driving who. So be careful out there!
 
I slashed a paddock yestrday and did nt find it to bad, didnt take out any fences or trees. But i will be getting a orc, but that could take all the fun out of it.

So with an orc, when you pop the clutch in the blades will stop pretty much straight away, so you dont need to wait for blade to stop before changing gears?? cause that would speed things up a tad.

Fergie on

No Mate. An ORC is a centrifugal clutch or perhaps a ratchet - it will turn one way, but lock up the other way.

When you depress the clutch pedal the ORC will disengage the tractor PTO whilst everything astern of the ORC - PTO shaft, slasher transmission and blades - will continue to free wheel rotate.

When you take your foot off the clutch and rev the engine so the PTO output wants to run faster than the slasher, the ORC will re-engage.

Bob (Aust) gave you a good explanation. But to clarify the gear shifting... The blades will continue to spin from their momentum, but they will be isolated from the tractor. I can shift gears, move from forward to reverse, etc all while the blades continue to spin down. Additionally, when I release the clutch the tractor doesn't have to spin the the blades back up from a stop each time.

An ORC is largely about safety, but it does make it easier to shift or change direction.
 
One thing to consider is the size of the pto shaft fitted to your tractor and the corresponding size of the drive shaft of your slasher . The length of the shaft will be increased when fitting the over run clutch , which might make it too long and necessitate buying a shorter shaft . The other size variation is in the pto shaft itself . Originals are one and one eighths of an inch , newer replacement shafts are usually one and three eighths of an inch. You may need an adapter either way or an orc that has different input and output sizes , depending on the style used these can also increase the overall length of the drive shaft .
 
For safety you should always use an Over-run Clutch on a Single Clutch tractor otherwise as you have already found out, it will keep driving the tractor until the blade stops and that could be dangerous if you are near any holes in the ground or trees etc. When the Blade is running you should not lift the Slasher too high as you rightly say it is dangerous, it could throw out something from underneath causing injury
You should lift the Slasher with PTO running until it is about 12" clear of the ground and as it is lifting, move the Lever forward until the 3 point stops lifting, but does not lower. At this point, move the Lever Stop to to the front of the Lever and you can return the Hyd Lever back to the point where the 3 point neither lifts nor lowers each time. This will only work if there are no leaks on the hydraulics, it should not be used for transporting the slasher any distance. When you transport, you should always disconnect the PTO from the Tractor and fasten it to the slasher so it wont drop off. Leave the PTO in gear and the Hydraulic Lever at the top when you do this, so there is no danger of the Slasher dropping and don't travel at speed especially on rough ground or around corners. On rough ground you can easily break something and around corners, the slasher weight will swing to one side and could make the tractor unstable. When the PTO shaft is horizontal, it is at its shortest, so you need to make sure that the shaft will close enough to allow the 3 point to lift. You will usually need to cut the PTO shaft when you fit an Over-run Clutch, be careful that you don't cut it too short. There should never be less than 3inches of shaft inside the other. If you lift too high the PTO can catch on the Slasher and may get bent, if it does it will not slide together and then it will push and pull at the PTO shaft in the tractor and can pull it out if it doesn't slide freely. If you need more information about any of this, email me and I will send it...tell me what Slasher you have.. most common one is the Bush-Hog..John(UK)[email protected]
