Designed for tractors from 450 to 720hp, Pottinger's Terradisc HT 12000 (12.5m) disc harrow is suitable for a variety of tasks including stubble cultivation and seedbed preparation, in heavy, dry soil conditions, and with large volumes of surface residues. Sitting above the existing 8.0m (8001T) and 10m (10001T) models, the new 12.5m trailed machine uses the same twin arm system with two disc carriers and two concave discs per clamping bracket, and the diameter and position of the discs (580mm scalloped or plain concave) is unchanged. The ground tracking system on the 12.5m horizontal folding model is new, with the four frame sections independently adapting to any ground unevenness. The inner sections can move between -3?and +6?and the outer two from -4.5?and +4.5?
专为450至720马力的拖拉机设计，Pottinger的Terradisc HT 12000（12.5米）圆盘耙适用于多种作业任务，包括秸秆翻耕和播种床准备，尤其适合在土壤重、干燥以及表面残留物较多的条件下使用。这款新型12.5米牵引式机械在原有8.0米（8001T）和10米（10001T）型号的基础上升级，采用相同的双臂系统，每个夹紧支架配备两个圆盘托架和两个凹形圆盘，圆盘直径和位置（580毫米波浪形或普通凹形）保持不变。12.5米水平折叠型机型配备了全新的地面跟踪系统，四个框架部分可独立适应各种地面不平情况：内侧部分可在-3°至+6°之间移动，外侧两部分则可在-4.5°至+4.5°之间调节。 |
