PTO and Clutch

khale · Jul 14, 2003

I am new to the tractor community and recently purchased a Hinomoto E2004.

I am trying to understand the relationship of the clutch to the PTO. I will try to explain.

When the tractor is stopped, I press the clutch in, put it in gear and put the PTO in a gear. upon Releasing the clutch, the tractor moves and the PTO moves, however after I am moving, if I press the clutch in again, the tractor will not stop until the PTO stops. This is very noticeable when you have a piece of equipment on it like a rotary cutter.

The momentum of the cutter actually drives the tractor forward until it all comes to a stop.
Is this correct???

This Link has a lucid explanation of PTOs of all types.

Edit:

Whoops, something got left off the first time around. The link should now work.

For a rotary cutter you need to unstall an overide clutch between the driveshaft and the PTO.

That means you have a single stage clutch.. and yes.. the inertia of the implimint can backfeed your final drives through the pto shaft... an over running clutch is great, and safer.

The rotation of the blades will definately keep the tractor in motion. You need one of these or any other model available.

khale,
You should go to Tractor supply website and order yourself an over-running clutch. That will eliminate the feedback through the transmission and be much safer. It will also let you stop easily, clutch and change gears without the gear clash while mowing if you need to change ground speeds. Buy the slip on clutch that is held on with the push button like your mower PTO. There are also clutches held on with a roll pin and they can be a pain to get on and off. You will find the clutch to make your mowing experience much safer, especially on side hills and ditch areas.

Here is a brief explanation of what's happening. The clutch completes the mechanical connection between the engine and transmission. The transmission drives the wheels and the pto when they are in gear. The clutch does not disconnect the wheels from the pto. As long as they are both in gear, they are mechanically linked through the transmission regardless of whether the clutch is engaged or not. Therefore, the pto can drive the wheels, and the wheels can drive the pto (if they are both in gear).

The over-running clutch is a ratcheting mechanism that allows the pto shaft to the implement to free spin in the driven direction, but not reverse. It allows the pto to drive the implement, but if pto speed drops suddenly, then the pto shaft to the implement and the implement itself are allowed to free spin until stopped by some other force, or until the momentum is dissipated by friction in the implement. This will keep the momentum of the implement from driving the wheels.

I hope this explanation helps.

If you have a digital camera could you snap some shots i'd like to look at your e2004 that's what i have. I've read some of these have or clutches some don't. I'm not sure if mine does or not i use a finish mower + tiller there's some pushing but not realy anymore than when the pto is off.

I don't know if the E2004 has a built in overrunning clutch. If you have an external one - its obvious. To check if you have an or clutch, try the following. Tractor OFF, in gear, pto in gear, try turning the pto clockwise. If it turns, then you have an o.r. clutch.
