I drive a Kubota ZG20. I mow my yards once a week in Louisiana. The yards I mow range between 3 and 10 acres in size so the grass gets weeds pretty fast (one week). My mower has lately been cutting good full grass great but when it comes to the skimpy grass with tall weeds it skips over the weeds pretty badly. Can anyone please make a suggestion? Going slow doesn't even work, and is really not an option for these yards. I have heard of gator blades should I give those a try?
