Phunter, are you a LawnCareOperator?
Both machines could serve a business well.
If it is for home use, I'd think ventrac would be the way to go.
But, if you have the money and are only going to keep a flail mower on the machine, the aebi is hands down the machine you want. They are way faster and can handle a lot more slopes and stress.
Looks like the right machine below?
We went up to bemidji just to check out the terra tracs as well.
When we can put either a reform or aebi into service, we will without a doubt do it. After looking at all of the "american" technology for these types of machines, the conclusion we came to is the european tech is far superior to ours. It may just cost a tad more, but we are willing to pay for a better product.
