They are now recognized as Tractor Mounted Personnel Transport Carriers or PTCs (as referred to by Cal/OSHA) but have gone by many names. Whether you call it a tractor basket, personnel transport platform or any variation of these, you have probably seen one in use as they have long been assisting workers on the farm as a transportation device.
Typically used for transporting workers in field irrigation operations, these devices had safely and successfully been employed for many years without issue as there was no specific regulations governing their use. Beginning in 2010 there were varying opinions on the part of Cal/OSHA regarding the legal use of these devices. That is until 2012 when they were in violation of Title 8 of the California Code of Regulations (CCR) section 3441(a)(2)(B), which prohibits "riders on agricultural equipment other than persons required for instruction or assistance in machine operation."
