Not having independent hydraulics and PTO must be the biggest draw back for the TE20. There were a few different types that were produced but I don’t know of any that are available now. One that comes to mind involves extended pins in the lift arms and bars that pivot on the top link and locate under the extended pins, I’ve a photo somewhere I see if I can find it.

I snatched these comments by the foremost Ferguson authority, from another forum, John(UK).

It is wear that causes the system to leak down, it wasn't designed to leak down like that.When there is wear the pressure will escape wherever it can. If it will hold up a 2 bottom plow (500lbs) for 10 mins that is acceptable, in work the Pump will be able to take care of that leakage, more than that it will not be able to maintain a constant depth. Why do you need it to hold up anyway, you should never park the tractor with an implement in the raised position without the Engine running, if you do this it can help the Control Valve to stick, more-so if the Pump has done a lot of work..John(UK).

Ha, I was thinking the same thing about making up a chain and hook that I could hook on to stop it falling, particularly good when I make/get a carry all to go on the back.

Right, I am ready to put the PTO adapter/clutch on but there is no way of fixing this to the PTO shaft coming out the diff casing.?...the previous adapter had a bolt through it and the shaft but this adapter/clutch has no such hole. It would appear with the sliding mech in the PTO shaft it could fall off. Answers please.

Also it appears my PTO shaft is too long,!,,, when I attach the topper/slasher on the machine the PTO shaft cannot be fitted as it’s too long, I guess I could pull the machine back a bit then insert the shaft but will be pushing on the PTO shaft all the time :sad:

I haven’t got to the stage of actually connecting the pto of my new topper yet but my understanding is that the clutch will either fit with a pin/bolt for which you will need a hole in the shaft or a quick release mechanism which will require a groove in the shaft to match the QR pin?

I also believe that shortening the PTO shaft connecting the tractor to the topper is required with an overrun clutch fitted.

I sure a “grown up” will be along shortly to confirm or correct my understanding.

Good luck! :)

HA, ALL SORTED, the over run clutch came with no instructions but on taking the two grease nipples out there is a hole right through that lines up with the hole in the PTO shaft, it came with a spring pin that you drive through it all to hold it in place then replace the grease nipples, grease and away you go.

The PTO shaft was not too long, just the safety outer cover, I removed 2” of that and it all fits together nicely. :dance:
