I have a question, I have just ordered a B2782B front mount snowblower for my B3030 tractor. I ordered it with both the hydraulic rotation and hydraulic deflection. My issue is the does this system come with a switch to change from rotation to deflection? My tractor does not have the third function . My dealer knows nothing and says they have no info until it comes in. I thought I read on this site that the kit comes with a seperate switch. If anyone knows anything please let me know.
