hi am new to this forum and had a few questions. 1. What is double blades, i am smart enough to figure out that it is doubling up two blades on one spindle but, what is the advantages, and what type of blades should be used. I currently have gator blades that have a half inch drop on them to help cut the taller grass. 2. I saw on an earlier thread that there is plans for the ECS handle to be made into a kit for the metro hp which i have, is that any further along and if not any time on that. and this is just a comment for the guys who have trouble taking off blades. Just bite the bullet and buy an impact wrench and youwill not have to use some combination of wrenches or worry about loosening up the spindles. it takes about 3 sec. per blade if that and i think it is worth every penny. i look forward to any help and talking with you guys in the furture.
