Next season I will be mowing with a lightly used Exmark Metro (32) for the first time. It is for ¼ acre of grass mowing 1-2 times per week. Mower came without both the grass catcher and Exmark micro mulch kit attachment accessories. I then purchased an Accelerator Industries grass catcher and so now that I am definitely going to bag and likely 75% of the time, I have a few questions. First, is there a noticeable benefit to getting notched airfoil (hi lift) blades because I am bagging, or will the standard blades, that likely came on the mower at purchase, perform in the same way as hi lifts? Second, will I be sorry if I do not purchase the cumbersome mulch kit (bolts and baffles to the deck) for this walk behind? I am use to mulching, mostly because I thought it was doing something good for the lawn, and because it saved some time. I am not certain that mulching has helped my lawn (I fertilize throughout the season); perhaps it has made the turf more compact and bumpy. Also, I am not as concerned about time because now the mower deck and bagger are larger. Finally, if I decide not to buy the mulch kit (because of $, switching accessories in season, disadvantages to mulching), will it benefit my lawn considerably to get mulching blades (gator) so then when the grass is discharged from the side of the mower, it is in finer pieces. Thanks in advance.
