I used this “Homemade” ATV sprayers for my vineyard the last 3 years, and last month the fan axel broke. What did this mean? For 3 weeks I had to back-pack spray to prevent powdery mildew. For those of you not familiar with this…You fill a spray pack with 4 gallons of water with organic spray material, like Stylet Oil, and then pump it to pressurize it continually and walk with 40 pounds on your back for about 5 miles. Not a lot of fun…but it should prevent disease later in the year. The good news for me is it has not been to warm, so the disease pressure is low!
Finally after waiting for 2 weeks for the replacement fan, I got it up and running last week and it seems as good as new.
