I am planning to calibrate the new rig today and had a few questions about it. I know Gary and some others use this machine, so hoping i can get some basics here, and some tips from experience for my first runs. 1. What can i expect from stock nozzles, and what color nozzle would give me 4K per gallon, and which for 2k per gallon? 2. My two most used dry materials are ammonium sulfate at 150 SGN and Lesco 44-0-0 at 240 SGN. Any idea how i might convert Lesco Spreader settings to the Exmark? 3. Best online place for Subaru spare parts? 4. Say I’m spraying a warning track of about 8-10 feet width, what’s the best way to attack that without drift onto the turf? I assume the deflector would be useful in this case? thanks for the help.
