Found the web site very useful some very good information here, but I can’t find the answer to my particular problem.
I have a MF35 fitted with a mill bucket front loader that we inherited with our small holding. I would like to ask two questions if I may;
The first is regarding the mill bucket, if there is no load on the rear arms the front loader will not lift, I have checked the oil level and that is fine. With a rear load on the arms the front loader works fine, but I think lacks lifting power.
The second question concerns the PTO.
I can engage the live PTO option (lever down) without a problem and the shaft runs continuously however when an implement is coupled to the shaft it becomes impossible to select the live position I get barking of gears and resistance in the leaver. I can however always select the ground speed option (lever up) effortlessly.
I have adjusted the clutch freeplay and turned the idle speed down none of which has helped.
I would like to run implements such as a baler, topper, and cultivator so I need the live PTO option, could you offer advice please?
First the PTO. You need to take off the bottom inspection plate and adjust the screws, the information you need to do this is on the MF35 PTO Clutch Adjustment Page.
As for the loader. Does the loader not lift when the arms come to the top (with no weight on them)? – Set the round lever somewhere in the response zone (between fast and slow), then use the square lever to operate the hydraulics.
The hydraulics lacking lifting power could be a whole host of things causing the problem. Probably the pump and control valve that is worn, but not necessarily, have a look at the MF 35 Hydraulics Won’t Lift Information Page and the Hydraulics DVD.
Hope that helps, just let us know if that hasn’t answered your questions.

I wandered if you could help me. I am lookinf for the piston protrusion height for a Standard 23C engine fitted to my Ferguson FE35 tractor. Also, do you know how many degrees before top dead centre before start of injection.
Many thanks, Jeffrey Samuelsen.
Afraid we haven’t got a figure for the piston protrusion height.
As for the degrees before TDC for start of injection it depends on the pump you have. For CAV DPA pumps without light-load advance is 19 degrees before TDC.
For CAV DPA pumps with light-load advance there are 2 pumps……
Pump DPA3242643 – 13 degrees before TDC
Pump DPA3242645 – 13 degrees before TDC
However, it should be understood that the initial setting using the ‘G’ mark inside the injector pump and the flywheel timing pin hole (when following the manufacturers timing instructions) will provide an injection timing of 17 degrees before TDC. Therefore you will need to adjust it from this point. Under no circumstances should the injection timing be advanced further than 19 degrees before TDC.
I have contacted you in the past and your information was very helpful. I am having a problem with water in the oil and don’t know how to get it out of the hydraulics can you give me any ideas.
Is it milky?
You will have to let the oil out and change it. There are 2 drain plugs. The oil in the rear transmission is the same reservoir for the gearbox and the hydraulics. Filler next to main gear lever.
Over the years they get condensation in this oil, or if the gear lever rubbers are split/perished.
The manual suggests changing this oil annually because of the condensation. In fact the less often the tractor is used then the greater the problem and more often the oil needs chaging.
Thanks for your reply yes the oil is milky. Can you tell me how to bleed the lines.
Because the lift cylinder is built with metal rings (similar to piston rings) any air will automatically escape as the system is used. Therefore there is no need to bleed the hydraulic system after changing the oil. The pump will also automatically re-prime itself.
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.
