With the forwarder, you just have to make sure that when you do the steep bits that you are absolutely dead square to the hill and that you don't have to make any turns, as it'll seriously destabilise you. I never descend with a full load, rather picking up bits along the way so that I'm only full right at the bottom. 

 

For reference, the largest log I've loaded on the fairly steep bits was a 4.9m douglas, 43cm TDUB and 60cm base diameter. A smidge over a cubic metre. That's starting to become a little oversized for the machine, at about 850kg.

You misread me, I used to pull a Botex trailer with a MF1200 tractor

I think I had you right - I was just explaining that it's much less unpleasant with a purpose built. I've only once had an uncontrolled descent in a tractor/trailer combo and it wasn't something I'd like to repeat.

Okay  but were you considering what happens when an articulated tractor pulling a trailer gets out of line, if the trailer overcomes the steering ram  it forms a letter N

That would indeed be a very ugly situation. I'm always really careful when descending not to hit a larger log or stump with just one of the front wheels. 

 

When breaking into a rack for the first time (after hand felling), it's inevitable that there will be product lengths in the racks. Sometimes I climb up into it to sort it out, but I can't always actually climb them if they are steep. I sorted one rack descending backwards, meaning easy sorting, but no product pickup and having to drive back to the top to load. Normally I just force my way down, reaching around the cab to move the logs. A big saw is a necessity to cut stumps down as even a tidy stump can be too much for the 40cm ground clearance on a steep slope.
