Query: saves time but you will still have to work at removing the weeds

A definite buy if you consider tackling sod or new applications with the mantis. Saves time and reduces the amount of time you have to spend taking the tines off. You still have to pop off the tines but the weeds slide off with these reducers and you don't have to spend an additional 5 minutes picking it off the shaft.
