I know there is one or two out there with deep product knowledge hence--
I`m considering an Al-ko 350 but i`m puzzled as to how they get the horizontal output drive from what appears to be a rotary mower engine?, or have I got this all wrong??
 Also are the tines likely to spin very fast as there is no obvious gearing down that you would get from a vee-belt side drive. -otherwise appears neat and not too heavy-any user/tech. advice appreciated-thanks

It is called a worm reduction drive.  The 'worm' or rotating thread is on the vertical shaft and the pinion giving horizontal drive meshes with the worm.  this form of gear box gives a large reductiion in speed and an increase in 'torque' so the tines will rotate slowley with the power to penitrate the soil.
