Sorry guys, pretty new to this. Just joined the forum. Anyway, just picked up a used permagreen ride-on centri. Guy i bought it from said he was running 4 oz. momentum per gallon of water. Machine has an 8 gallon tank and he said it does 32,000 sq. ft in 8 gallons. I just thought 4 oz of momentum sounded a bit high. I understand that the amount has to be more because it covers more area and that the water is just a carrier however, just wanted to double check. Thanks again guys appreciate the help.
