    Re: 3 phase : rotation of motor.

    If it has an auto cutoff switch, it will be a very useful tool. I fitted a limit switch which operates when the blade cuts through and drops a few millimetres. Insert the material to be cut, press...

    And beware a trap for young (and old!) players: my JD ride-on has a seat switch which has twin contacts. I forget the detail of how it works, but simply jumpering it with a length of wire does not...

    Good info, FF. Thankyou.

    Which filters have the best filtering capacity: engine oil or fuel?

    One of my snouts remarked privately that such contact could not be made with a standard bucket, and he confirmed what I had wondered about. It would be very bad design, if it was possible normally.

    Re: Best tractor ever made?

    Surely the MF 100 series? I have 3, all still available for work whenever I want!
