    3 functions on the right hand control bank stopped functioning simultaneously. Blade lift and wheel lean still function, which are side by side in the centre of the valve, while the circle shift, artic, and scarfier do not work at all. The operator mentioned he had moved the scarfier upon start up. nothing blatantly obvious upon visual inspection. levers still move freely, but nothing happens. Any ideas?
