(d) All self-propelled equipment shall be equipped with a braking device controlled from the operator's station, capable of preventing the vehicle from moving while parked.
(e) Where mobile farm equipment is towed by a tractor or truck and the tractor or truck driver cannot see the employees on the towed equipment, a positive signaling device shall be installed on the towed equipment, or there shall be a device on the towed equipment that can be actuated to stop the towing equipment in case of an emergency.
(f) Engine exhaust systems shall not be piped into or through an enclosed cab on tractors or other equipment.
(g) All tractors, self-propelled farm equipment, and trucks used between sunset and sunrise shall be equipped with at least one headlight which shall be used to illuminate the area in front of the equipment or truck at least 50 feet. There shall be at least one rear light which shall illuminate equipment at the rear. Additional lighting shall be provided where the operation requires field adjustment or the operator's attention.
NOTE to Subsection (g): See Section 3449 for illumination requirements for working near agricultural equipment during hours of darkness.
(h) Adequate means of access shall be provided so that employees can safely reach the top of the load for manual loading or unloading of high loads.
(i) Tractor-Mounted Personnel Transport Carriers (PTCs).
(1) Use of PTCs shall be allowed only for employees who are installing, removing or maintaining irrigation pipe for low-lying row crops. No other employees shall be allowed to board or ride on PTCs. When the term “tractor” is used in subsection (i), it means “agricultural tractor” as defined in Section 3649.
(2) Employees may ride in PTCs only in the furrowed area of fields while performing irrigation activities.
(3) The slope of the fields where employees ride on a PTC shall not exceed a 5% grade.
(4) PTC Design and Construction.
(A) PTCs shall be approved for their intended use as provided in Section 3206 of these Orders.
(B) For existing PTC units built prior to the effective date of these provisions, January 1, 2016, a qualified person shall inspect and approve the PTC units for structural integrity and design prior to the units being placed into service.
(C) Seat belts shall be installed for all passenger positions on PTCs.
1. Seat belts shall be labeled as meeting the design requirements of the Society of Automotive Engineers (SAE) J386 JUN85 or JUN93 standard, Operator Restraint System for Off-Road Work Machines; or
2. Seat belts shall be equivalent to the tractor operator seat belt provided by the tractor manufacturer.
(D) Sufficient steps and handholds shall be provided on the PTC so that employees can maintain a three-point contact while entering and exiting the PTC.
(E) PTCs shall be designed with a safety chain, door or gate at each passenger entry/exit opening that shall withstand a force of at least 200 pounds, applied vertically downward and horizontally outward on the exit side of the PTC opening. Passenger entry/exit openings shall be kept in the closed and latched position whenever the tractor is in motion.
(F) Each PTC shall have an effective and reliable means of communication by which passengers can relay an emergency signal to the tractor operator. When the tractor operator has a clear line of sight to the PTC passengers, verbal communication meets the requirements of this provision.
(G) Structural elements of the PTC shall be constructed of steel. The strength of the elements shall be sufficient to support the anticipated loads.
(H) All welding or repairs affecting the structural integrity of PTCs shall be performed by a qualified person.
