i started this thread because i debate this point with other guys i work with and they dont see it like i do , so i plan on copying this thread to show the replies to co workers . ive never read others outlooks this is just mine from doing lawn maintenance 15 years . were at week 5 of cutting season in southeast michigan . when we got to weeks 3 and 4 i started calling for diagonal cuts for several reasons , diagonal (corner to corner) as opposed to whats usually the quickest side to side or back to front cuts which paralell the property lines and which mowers most of the time run . well at week 3 after 2 weeks of cutting wet turf my opinions this : weve been leaving ruts in soil in same pattern two weeks , nows the time with soil still soft to roll some of them out with a diagonal pattern . also after 2 or 3 weeks in same direction lawns laying down in that direction and if you go diagonal you'll come at blades from different direction and be able to get a better cut because you'll get a better lift of blades as opposed to them not standing up for a better cut but rather staying laid over and thusly causing alot of missed blades / stragglers . if im running the mower every 3rd or 4th week max i diagonal cut for these two reasons . its pretty much cut n dry logic to me . but im wondering others outlooks on it
