I have had PG machines in the past and this year we are due for a new machine. Things have changed alot over the last 3-5 yrs. There are a few companies out there offering these machines. PG Turfco Z spray. For those that have used these - which one? I am running smallest 5K to doing a 3-4 acre complex. So I used the PG - most versiable for me but just wondering what you guys thought that have used these other machines.
