My machinery ring has decided to replace a 2.8 horizontal topper with a 3.2m(small dick syndrome), but hadn't realized that with the guards it is wider than 3.5 (transport width in France without an escort)so it isn't as handy !!!!!!!.. I've been looking into buying one visit, and the cheaper brands have 540 pto and the more expensive 1000. What's the difference, is a 1000 likely to be more robust is there a more technical explanation?
