i have a small lawn service of 40 customers,i provide maintenence and weed and fert,yes i am licensed. anyway i have become interested in electric spray rigs, are these reliable? are they powerful enough to put down a pre-emergant at proper rates? im thinking of trying to go lighter and quieter, since most of these are residential under 20,000 sf . i think 100 to 150 gallon size skid mount we be great. ive done weed and fert for five seasons at local companies so im pretty seasoned here in the transistion zone in n/e okla. i am fully aware of the virtues of gas rigs so humour me.
