Field marking system

A sprayer comprising:

• a chassis;
• a plurality of ground engaging motive members supporting the chassis;
• an engine supported by the chassis;
• a transmission operably connecting the engine and the plurality of ground engaging motive members;
• a main fluid storage tank supported by the chassis;
• a boom extending from the chassis;
• a plurality of main nozzles carried by the boom and fluidly coupled to the main storage tank;
• a foam solution storage tank supported by the chassis;
• a mixing volume fluidly connected to the storage tank and configured for mixing foam solution from the foam storage tank with pressurized air;
• a nozzle carried by the boom and fluidly connected to the mixing volume;
• and
• a turbocharger coupled to the engine to supply pressurized air to the engine, and coupled to the mixing volume to supply pressurized air, without further mechanical compression, to the mixing volume while the engine is driving the ground engaging motive members to propel the vehicle.

A field marking system for use with a vehicle having an engine with a turbo charger and ground engaging motive members, the system comprising:

• a marking solution storage tank;
• a mixing volume fluidly connected to the storage tank and configured for mixing marking solution from the marking solution storage tank with pressurized air;
• and
• a nozzle fluidly connected to the mixing volume, wherein the mixing volume is adapted to be pneumatically coupled to the turbo charger, whereby the turbocharger supplies pressurized air, without further mechanical compression, to the mixing volume and to the field marking system while the engine is driving the ground engaging motive members.

An agricultural applicating system comprising:

• a material storage tank;
• a mixing volume connected to the storage tank and configured to mix material from the material storage tank with pressurized air;
• an applicator connected to the mixing volume;
• an engine including a turbocharger, wherein the turbocharger supplies pressurized air to the mixing volume;
• a vent valve connected to the tank;
• and
• a fill valve connected to the tank, wherein the vent valve and the fill valve are configured such that the fill valve cannot be opened until the vent valve is opened.

A field marking system comprising:

• a marking solution storage tank;
• a mixing volume fluidly connected to the storage tank and configured to mix marking solution from the storage tank with pressurized air;
• a nozzle fluidly connected to the mixing volume;
• and
• an engine including a turbo charger;
• and
• a receiver tank pneumatically connected in parallel between the turbocharger and the mixing volume.
