I have a 150 gallon Gearmore sprayer for sale. The unit is approximately 15 years old. I have been using it on my 3 acre apple orchard. The last 8 years it has only had organic sprays run through it. The unit works well. The pump uses some oil once and awhile. Probably needs a pump rebuild.
The controls for this sprayer are normally mounted to the fender for easy access. At the time the picture was taken the controls where not mounted to the fender.
