A combination of an attractive appearance and positive environmental credentials may seem an unlikely sales pitch for a humble ballast block, but that is what Lynx Engineering claims for the latest addition to its already comprehensive range of tractor weights.

The new RT Series front-linkage mounted blocks are made from recycled concrete wrapped in pre-coloured, high-density polyethylene (HDPE) that is also from recycled sources, so there is little in the way of virgin steel and no paint involved.

HDPE advanced thermoplastic is durable, impact resistant and impervious to water and cleaning fluids.

Because it does not peel or discolour, it presents a smart initial finish that will be maintained throughout its life, reckons Lynx.

Four sizes are available – 800kg, 900kg, 1,000kg and 1,200kg – and some versions come with an integral 45-litre capacity toolbox.

All have lower lift arm pins, a top link upright with a towing clevis and pin, and each can be customised with a user’s name or logo.

The RT Series blocks join Lynx Engineering’s Wel-Weight magnetite weights, which have a steel case enclosing a material with two and a half times the density of reinforced concrete – so they can be smaller and sleeker for the same mass.

Sizes span 600-1,200kg with a 500kg add-on weight available.

Much the same attributes as the Magnetite blocks are claimed for the monobloc and more flexible, two-part drive-in weights made from a cast mineral composite in sizes 800-2,000kg.

Also available are Mufo cast steel weights in 600-1,500kg sizes, including versions for mounting on a tractor’s front weight frame; cast concrete 650-1,500kg blocks; concrete and steel Mono multi-block designs for variable 650-1,500kg ballast; and both Eco-Box and Pro-Weight ballast toolboxes from 1,050-2,000kg.
