I have been using Toro 340 Multistream fora bout 5 years or so now. NO issues until now the heads stopped spinning. I tried cleaning them out and everything but still no fix

. I really liked their coverage and it worked quite well for my design.
They don't make that head any more.. they make the 300 series with smaller coverage, i would like to stay with multi stream type of head.
What do you guys recommend i need something with about 25 foot reach that won't wash away open garden soil.
