The 16kva genny I have I bought from your Dad, and it's a great bit of kit but we use a pft zp3xl for flow screed and it needs a bit more umph to pump at full pelt for extended periods of time, we seem to be doing larger pours recently, 17m3 the other day and I like to keep plant up to date and functional. Hope you're are healing well Ryan, looked painfull!
