float

1. an instrument used in the filing or rasping of a horse's premolar and molar teeth. Handles are 24 to 28 in (60 to 70 cm) with a broad head into which an interchangeable rasp can be screwed. Some rasps work when pulled toward the operator, others work only when pushed away. Short-handled floats with the heads set at an angle are used for the front upper molars.

2. in British countries, the term for a road vehicle used for the transport of large animals, usually horses or cattle. A low-level float may be an independent unit towed behind another vehicle. A high-level float is standard-truck height and an integral part of the vehicle.
