1.    All tractors:

1.1.   A roll bar, of sufficient construction to protect the driver in the event of an overturn, must be fitted.

1.2.   Wheelie bars, of sufficient construction to carry the weight of the tractor, must be fitted. The wheelie bars must protrude outside of the diameter of the rear tyres and must be no more than 300mm from the ground.

1.3.   A seat belt, that is sufficient to hold the driver in the tractor seat, must be fitted.

1.4.   All mechanical (engine driven) fans must be sufficiently guarded so that in the event of a fan failure no part of it can escape from the engine compartment.

1.5.   Throttles must return to idle when released.

1.6.   Tractors must be deemed "fit for purpose" by the PVTPC scrutinisers, e.g. Batteries and weights secured, relevant bodywork in place etc.

1.7.   All exhaust pipes must finally direct gases vertically. 

2.    Additional conditions for non-turbo tractors

2.1.   A remote stop must be fitted to the tractor which will allow the sledge operator to stop or reduce the engine to idle, this may take the form of a kill flap over the air intake or a fuel cut off. The remote stop cable must be terminated at the rear of the tractor within easy reach of the hook person when being attached to the sledge.

3.    Additional conditions for turbo tractors

3.1.   A kill flap must be fitted to the tractors air intake which will cause the tractor to stall or be reduced to near idle rev's when operated. The kill flap cable must be terminated at the rear of the tractor within easy reach of the hook person when being attached to the sledge.

3.2.    Cross bolts must be fitted in the exhaust pipe which are sufficient to stop a complete turbo impeller leaving the exhaust pipe. A minimum 2 number 10mm 8.8 grade bolts is required, more bolts maybe required in larger diameter exhaust pipes.

4.    Additional conditions for tractors using any other fuel instead of or in addition to Diesel

4.1.   Tractors must be fitted with a fire extinguisher that is suitable for the type of fuel being used. (For more information see http://www.firesafe.org.uk )

5.    Additional conditions for high revving tractors (over 3000rpm Approx)

5.1.   Tractors must be fitted with a steel flywheel

5.2.   Tractors must have bell housings sufficiently guarded so that in the event of part or the entire flywheel becoming detached it is contained with the confines of the tractor. This may take the form of a shatter blanket or 10mm thick steel shroud around the length of the bell housing.

5.3.   Tractors must be fitted with side panels that are sufficient to stop engine parts leaving the engine compartment in the event of catastrophic engine failure.

5.4.   Tractors must not be fitted with mechanical cooling fans.
