My OH tipped our Siromer with the forklift high, plus load (not one of his on-the-ball days
), when a front wheel went into a hole. So no, you are not worrying too much. I think I am right in saying that the old kinds of tractor with the front wheels close together are prone to that as well, but that is not what you are looking for. It would be sensible to attend a Health and Safety course, and a tractor driving course, before you buy and drive your tractor. There are so many dangers involved with tractors, such as pto shafts, that you need to know as much as you can before you get one. (we are all supposed to go on a H&S course anyway and they do emphasise the tractor and quad accidents to catch your attention).
Apart from the tipping accident, our Siromer has been great - think it's 22 hp. We didn't buy it with the front loader on but we eventually realised we would have to get one and that is the most useful bit, for turning compost heaps, lifting heavy things, carrying things around when we don't want to use the trailer and the backbox is full (remembering to carry it with the front loader low
) We also have a pto-driven rotavator attachment which has been very useful, a plough which we used a lot at first but not much now, a roller and rakes, and a very useful topper.
What it can't do is run the hay mower, tedder or baler - fortunately we have an ancient David Brown which does those things for us once a year but doesn't get used much otherwise - except in the tipping incident when a hefty shove from the DB put the Siromer back on its feet
