This information is for the Ferguson TEF20 tractors, and identifies any changes that have occured during the production of the tractors. This list can help identify the serial number of your tractor if the identification plate is missing. This information below is an extract from the Wallaces website. Unfortunately, the Wallaces Ferguson website does not seem to exist any longer. This is a shame, as they had a nice chart which was a cross-reference between the TE20 engine number and serial numbers. If anyone knows of a similar resource then please let Vintage Tractor Engineer know, as this would be good information to have available.

Garry Beutel, between the gear box and the back axles or dif, the is a plate that when the gear box is full it flows over this plate so an equal amount between both is made, this plate doesnt go from the bottom to the top it only goes part way up, so it allows oil to fill up gear box then when that is full it flows over to the dif. i cant remeber which side of the join between the gear box and dif this plate is located, but if you ever crack your tractor in 2 you will see this plate.
1194 kg up to serial number 32500, after this serial number 1226 kg.

I have TE20 Ferguson Tractor with the following number on the 3 Cylinder Engine Block: 11007. Can this be cross referenced so that I can obtain the correct parts?
Hi, i have a hydrauic porblem on a te20. it will pick things up fine but if i clutch to get in gear, it will loweer, so i cant get anywhere withut ploughing up the first meter of land. is this a valve problem, or gaskets to the lift pump leaking, or the piston rings?
any advice appreciated
Have a TED20 and when I fill the greg box oil the oil does not fill to the required level— as the oil flows out of the overflow hole near the back of the engine– is their a seal between the gear box and the diff hopeing you can help
did tef’s have air intakes on the bonnet…the list is not for diesel is it, it is for one of the petrol models?
eddie- if the tractor is stationary, you put the hyd lever in lift, pto out of gear i think, then rock the pto shaft side to side, you hyd arms will lift.
alex-i think they are still around, just look in magazines and websites.
Bryce- 1- the cap to the left on the gearstick(when you sat on the seat) does the gear box and hydraulics. the plug in the steering column is obviously for steering.
2-i think its something like 25 litres of oil..
3- the oil i used was general purpose stuff, suitable for steering, gearbox, and hydraulics-(and possibly engine-but my engine already had oil in)
4- yes, hydarulics can stop working if the oil is too milky and not thick enough.
hope this helps
Hello, have purchased a ted-petrol/paraffin (tvo). The question i have over it is the serial no plate is not on and there is no sign of it ever beening on. It’s original tin work and not been restored or messed with, it’s 6volt and there a number to the left of the steering wheel but not stamped but embosed. Hope you could give some help or contact web site, the one above “wallaces” does not open.
Thanks very much, cheers
I have a TE 20 and the hydrolics don’t work. I have checked the oil in the dip stick on the side hand side sort of under the seat and it is white, from water.
I presume the water is causeing the hydrolics not to work.
I have removed the oil plug from under the diff as well as from under the gear box and drained the oil, both white in colour from water.
My question is this.
1. Do I fill the oil back up via the 1″ bolt near he gear stick for both these areas of the “sump”, being the gear box and the diff?
2. How much oil do I need?
3. What type of oil?
4. Does this sound like the way to get the hydrolics working again?
Very kind regards if you can help.
ps. I have just built a shed so hopefully no more water will get in.
I bought a TEO – 20 but the starter and the distributer are missing. Can i get any nearest or modify and use something that can be obtained easily?
The hydraulics control lever is down by the right hand side of the seat.
The TE 20’s only had a single clutch, so the hydraulic pump only works when the clutch is released (either in or out of a transmission gear). Therefore, the hydraulics will only work when either the tractor is travelling (forwards or backwards) or when the tractor is stationary, out of gear and the clutch pedal is released.
can you tell me which lever or pedal to push to lift the rear hydrolics off the ground so i can move it
getting water in oil but engine runs like a sewing machine??????
