Brand spanking new and unused. Genuine John Deere compact tractor ballast box that acts as a counterweight when using a front end loader. Compact and heavy construction, it is usually filled with something like biulders mix or metal for extra weight. Shed stored. The box measures 600mm wide, 450 deep and 520 high. Empty it would weigh an estimate of 50-60 kg. Using a filling medium of eg:builders mix at 1.7 tonne per cubic metre, it would give a maximum of approx 300kg of counterweight if filled to the top. Less if partially filled. Surplus to requirements
