Chapter 1: ETPC COMPETITION RULES A. ETPC The European Tractor Pulling Committee is the coordinating organisation in Europe. The European Tractor Pulling Committee is an association, whose objectives are to pursue and promote truck and tractor pulling in the widest sense in Europe.
Warranty disclaimer The rules in this book are intended as guidelines for the sport of truck and tractor pulling, and the rules relating to the safety of the equipment are the responsibility of each driver who participates in the sport of truck and tractor pulling under these rules. No expressed or implied warranty of safety is intended nor may be inferred from the publication of these rules, nor the compliance therewith.
C. Entry procedures 1. Each vehicle may enter at two classes, but only once at each class. A vehicle must compete in a class at that individual event before it can receive points or starting money. 2. A puller receives no starting money or points unless there has been made a measurable pull in a class. 3. No mixing of classes. 4. Classes in a given session will be run in that session, but not necessarily in the scheduled order. 5. Once a puller has scratched from a class, he may not re-enter. 6.

Chapter 14: ROLL OVER PROTECTIONS 1. 2. 3. 4. The Driver Roll Over Protection (ROP) has been designed in co-operation with specialists in order to protect the driver in the event of his vehicle tipping over during a tractor pulling competition. The design, or the ROP built according to the given specifications, are not to be understood as an automatic guarantee, as for providing an always adequate protection for the driver during an accident with the tractor.
12. It is recommended that the fastening construction of the ROP cage to the tractor frame is significantly stiffer than the ROP itself. 13. It is also recommended that the driver’s seat should be so constructed that it provides adequate back and shoulder support during an accident. The seat should be mounted to the ROP cage, or the lower support structure with at least four (4) M8 grade 8.8 bolts. The seat back should be bolted to the rear main hoops, and the seat should include a head rest. 14.
