I stirred up a batch last week, dumped it in the tractor-mounted spray rig and set off across the fields, engaged the pto and nothing happened !! Now the queston is, do I need to fork out to repair the pto-driven diaphram pump or will a slightly cheaper 'Hypro' make, roller pump do ?? What is the established wisdom on this list, a roller pump would not be suitable for spraying compost teas because of the violent mechanics involved, but surely with 500 we are dealing with forces, right ??   Gideon.
