Let me start by saying I'm new to the ride on and the t3000i is my first one after 19 years in business. Yes I'm licensed. My question is I am having difficulty understanding the amount of herbicide for 16 gallons. I'm using celcius, stonewall, strike 3, triplet now, no not in the same mix. Each label states to apply in well over a gallon of water/1000sf. the t3000 uses .25gallon /1000sf. I'm confused. Can any fellow t3000 uses tell me how much of the products listed they mix with 16 mix. Also, the book says to premix outside of the t3000 but I've heard others on here say they mix within the t3000. Whats the deal. Thanks for any assistance.
