When you build a disc harrow like the Model 1544 with the strength and heft to penetrate tough soil and heavy residue, you’re talking about a lot of weight … particularly on acre hungry 42’ and 45’ models. Unfortunately, many manufacturers forget that fact. And flotation tires can be expensive. That’s why you’ll find eight tires on four sets of walking tandems on the ground during transport. The benefits include safer transport and better flotation in the field. In the meantime, the 1544 offers unmatched flexibility in rolling terrain and terraced ground, thanks to its four section design and heavy-duty compression springs on each pivot point.
