I purchased the Tekton 15356 1/2 in. drive x 25 in. breaker bar in February of this year. I bought it for the purpose of changing the blades on one of my mowers. Since I mow for a living, I change the blades on this mower about once a week. The additional length of this breaker bar makes changing blades a snap.
Prior to buying this breaker bar, I used a 18" Craftsman breaker bar and a cheater pipe to tighten the blade nuts to the recommended 100-120 lb ft. That setup worked for several years but doing away with the cheater pipe makes things safer and less complicated.
