Abstract
A low-profile liquid storage tank and vehicles incorporating same. An exemplary low-profile liquid storage tank may define an interior volume having an upper surface that defines an access port, and a lower surface that includes a fluid impingement portion positioned below the access port. The impingement portion may include two or more undulations formed in or on the lower surface of the tank, the undulations adapted to assist with reducing splash-back of fluid added to the tank through the access port.
Claims15
A grounds maintenance vehicle, comprising:
- a frame;
- and
- a low-profile liquid storage tank attached to the frame and defining an interior volume, the tank comprising:
- an interior upper surface defining an access port into the interior volume;
- and
- an interior lower surface comprising a fluid impingement portion positioned vertically below the access port, the impingement portion comprising two or more undulations formed in or on the lower surface of the tank, wherein the impingement portion defines a serpentine shape when viewed in cross section.
