The weight is a new critical factor because of the rising fuel cost but also because of the vast amount of soil-compaction.The Fastrac is far too heavy for transport work due to the design ignoring the UK regulations that now exist.The weight of the trailer is part of the legal requirement of tractor,trailer & load.Under existing regulations, the maximum load that a 10.65 tonne Fastrac ,working with a Larrington 6tonne trailer is legally allowed to carry is just 7.65 tonnes which is about eight x one tonne silage bales.
