    I have recently bought an Allen scythe which runs beautifully, but I can't set up the wheel drive clutch to reliably disengage. The manual I downloaded from this site doesn't help very much - it's difficult to work out how the clutch release mechanism works from the exploded diagrams. Any tips on setting up the clutch before I do some serious damage to something/someone?
    Ideas gratefully received.

    Sorry I can't help with the setup but I used them a lot in my youth and remember the creeping clutch as a 'feature'.
    Tales of people having their nether regions sliced are legion and the machines are best not left running unattended.

    Disengaging clutches on allen scythes

    Disengaging the clutch on the allen scythe is often difficult, particularly when they are suffering from even the slightest wear, according to the instruction manual I have, the best method is to "push the handles smartly downwards whilst attempting to disengage the clutch."
    I have tried this with succes on all three of mine, however, sometimes the clutch will not disengage until your knuckles are almost touching the floor!!!
    I figure that this method works as it momentarily takes the load off the clutch allowing it to disengage. Perhaps a smart push forwards if you aren't working in heavy growth may also do the trick?
    Hope this helps.....

    Thanks for the tips. I have now dismantled the main gear casing and discovered that the head of the selector fork had broken off - the rod would still push the dog clutch together, but it couldn't pull them apart. Looked like fatigue. The end of the rod had been turned down a narrower diameter, leaving a shoulder. The narrow end was pushed through a hole in the fork and peened over to retain it. I have had it welded this time. I will reassemble soon, and try your tip about taking the load off the gear train by shoving downwards.
