I grew up driving tractors and diggers, it's a very similar thing. Up and down, up and down, Perkins AD3 at 1700rpm for 540rpm PTO shaft speed, it all sounds like a mantra. Write a prayer on a strip of paper, wrap it round the shaft, offer up a prayer nine times a second.

Poetry. I'm not Buddhist but I find the 'metaphysics' of their prayer wheels fascinating.

I'm not a Buddhist either but the Tao helps me find the Way to accept diesel being nearly two quid a litre right when the good weather starts and all the fields need worked.
