The Ryetec Smartbox uses removable weight inserts in a central box, so ballast can be changed for different implements, whereas the LT and Compact Weightboxes use a permanent concrete counterweight. All Smartbox models are supplied ready for three-point linkage mounting.

Ryetec Smartbox concrete weight blocks are available in 600 kg, 800 kg, 1,000 kg and 1,500 kg, plus 200 kg belly plates. Because the inserts are removable, ballast can be changed on demand rather than being fixed for the life of the box.

The standard Weightbox & Workbox weighs 400–2,000 kg and fits Cat 2 linkage. The Compact version has a counterweight of up to 1,000 kg and projects less. The LT is a lower-cost box with 600–1,500 kg of permanent ballast. The Smartbox has removable weight inserts in three sizes, and the very compact Workbox Mini fits Cat 0/1 or 1/2 linkage.

Yes, on most models. The Smartbox takes optional removable weight inserts, and the standard Weightbox & Workbox, Compact Weightbox and Workbox Mini have a detachable underslung weight block for adding or removing ballast. The LT Weightbox uses a permanent concrete counterweight, so choose its weight to suit your heaviest implement.
