We checked the fuel and it wasn't the cause. Was cutting up with the 084 then I heard the pop and I was like f@#$!!!. The 365 came off a 2 month spell' and it popped after the 1st hour of use.
The public is very unaware with Rhus as they are treework Eric. You know what is hilarious? We went and quoted a job the other day, on the customers nature strip she had two Rhus trees that had been chopped n topped by the council - they sprayed the stump hi vis orange for them to be knocked down and ground. Well 1 year later 2 metres taller with epicormics after the chop n top the council still hasn't been back to grind it

.
They probably went home with a mad rash and were like F going back to that thing.
There is a similar tree that gets the same beautiful effect a Rhus does and looks very similar with out the toxins, it is the
Pistacia chinensis the only visual difference is that the Rhus has a terminal leaf where as the Pistacio doesn't.
