TN236 Trencher for Mini Tool Carrier The ideal solution when you need to cut a trench in a tight space, the TN236 Trencher is small but aggressive. A great tool for landscapers, the TN236 Trencher is designed for mini-skidsteers and mini track loaders between 1500 - 4000 lbs. The TN236 will cut trenches up to 36” deep and between 4” to 6” wide, depending on the chain option. The TN236 Trencher is powered by a planetary drive system. With no roller chain to worry about, the planetary drive unit delivers hydraulic power directly to the sprocket of the digging chain for optimal trenching performance.
