Hello IronHorse,
Regarding mulcher rotation, I understand what some customers we've heard here mentionned: by going top backwards, you throw some possibly hazardous projections much further away in front of you. That's not a problem if you're alone far out in the woods, but it might be a concern for pedestrians or drivers if you're closer to roads and houses.
Having said that, the guys that run our excavator-mount models use both direction while working. To better understand, from the operator's cab on a standard excavator, you would see the drum rotating counter-clockwise. So here's what they do:
1. Using the swing, they do a first pass from right to left, at maybe 2 or 3 feet above the ground. This clears the vegetation cover and reveals the rocks that might be underneath.
2. Then, swinging back from left to right, the go closer to the ground with the nearer-end of the brushcutter almost touching it. They then clear the rest of the vegetation, avoiding the rocks by using the bucket cylinder.
So, on the first pass, you're working basically as you would be on a skid steer. Rotation of the drum is seen by the vegetation as being from the top down.
On the second pass though, you got it, rotation is then seen as bottom up (is that the right expression? Correct the French Canadian if not ) What is interesting when they go on their second pass though is how they use the bottom-up movement to pick-up material that is on the ground and suck it into the rotor.
I'd like to invite you to visit this video, where you'll see how it goes one way and the other...

... however, the movies are only in QuickTime for now. I'll have Windows Media Player formats done next week and I'll post the link here.
Regarding vertical-shaft vs horizontal-shaft brushcutters, you'll find you'll throw more stuff with the vertical-shaft and so you'll work longer to get the same clean finish you'd get with a horizontal-shaft. However, cost can be significantly lower, which is a good reason for some people to go with it.
However, if you're looking for production and nicer finish, I'd suggest to go with the horizontal-shaft one.
And regarding your nice 23-tonne machine, is it really a Jonyang 230E? I've just read the specs and that looks like a nice setup: 170 hp and 2x62 gal/min max flow... Good for you. I'd be interested in knowing who you got it from...
By the way, we have been doing excavator-mount brushcutters for over 15 years now. PM me if you would like to have more infos on our DAH-150E (that's the model for that size of excavator, no power-pack needed).
