Some may say WTF to this question (maybe not TX), but last year we went through 100 plus trenching shovel for our install crews. Hard clay and rock from H E double hockey sticks is on 90% of our projects. We tried the Corona shovels only to break the handles and all of the Ewing/JDL yellow handle end up with cracked welds. I am not joking and this has become a big issue for us. King of Spades all steel shovels are too small and we even began fabricating our own, but it is not practical during to summer months. We just ordered a batch of these Model #92720 http://www.bullytools.com/shovels_trench.html Any input is appreciated?
