This file tells me how to mow my 🌾︎ grass lawn, using my Honda lawnmower, model=HRR2169VKA EJ, serial=MZCG-9229225, manual (.pdf).

I love this mower!  Light, fast, reliable, and it mulches very well!  I love it!

This file is a reminder for me, particularly at the beginning or end of the season, or whenever tired, hungry or grumpy!

Prepare, mow, finish up.
Other considerations.   Eric:  When you change this document, also 📄 print and post on mower!

Prepare

Prepare to mow your lawn whenever it is growing, ragged, or 50% longer than your mowing height in the table below (15 cm 6 in).  Maybe every 10 days, depending on the season and weather.

Respirator

If after mowing, vacuuming the basement or blowing out the garage, allergies ever interfere with an awesome night's sleep, get (and use!) a
😷 P100/N99/similar HEPA respirator/​filter mask cartoon of person wearing a filter mask … I hate when people wear these in public.  Like OK, we get it, you are a surgeon. … select to view full-size that removes from the air 99.97%/99% of particulates down to 0.3 µm (about the size of a virus).  Pending further testing, I am here not recommending N95 (removes 95% of these particles) or inferior filters.
Among your options:

I find Lowe's has a better selection of PPE and lighting v. Home Depot.

After purchasing your respirator, please continue:

Happy mowing!

Finish up
