I am just getting into the business and i have read some of your tips. This is just a part time thing for me because my full time gig is with Uncle Sam. First, let me say thank you for posting your tips as they have already taught me a thing or 3. I read the tip about sharpening the blades everyday or at least every 4 yards. I also see that it is a good idea to have an extra set of blades on hand. That brings me to my question...to mulch or not to mulch. I am going to buy an extra set of blades, but they do offer a mulching set and a regular set...which set should i buy? I have been told here where i cut, most companies do not bag...so should i mulch instead? And if so should i buy the mulching kit that comes for my mower with 2 blades and a block for the discharge port. Thanks and keep up the teaching topics...i real them all!
