Im putting in a quote today for a property manager that has several lots that haven't been touched all year. Most have waist high grass and heavy weeds. They are all quite small and I know I can blast each one probably in about 20-30 min each with the right wacker. Lot sizes are only about 20'x50'. What trimmer do you guys recommend for high/heavy/thick weeds and lots full of tall grass? Id like to keep it under 300. Any suggestions are most appreciated.
