Fimco Sprayer 110-Gallon Boomless 3-Point

Operating manual for sprayer for blue nozzles says to run pressure at 60 psi with tractor speed at 4 mph to get 17.5 gallons of liquid per acre. Pressure gage that comes with sprayer is 0 - 400 psi with 100 lb. increments, which makes it difficult to regulate 60 lbs. of pressure on 1/4 of the scale with any amount of accuracy. The suction hose from the tank to the pump will collapse when trying to get 60 psi and maintaining a steady spray volume. It is a cheap hose and is not collapse proof. It had to be replaced with a supported hose. You would think that the manufacturer would specify a better range for the pressure gauge (0 -100psi or 0 -150psi) to give more control of pressure for spraying expensive chemicals. They need to upgrade the suction hose to prevent loss of flow to the roller pump that could damage it. Just two items that cost over 4hrs of lost time while trying to spray a field.
