I own an Antonio Carraro TTR4400 which is reversible. This is a 38HP 4WD machine with reversible operators station. What is 'behind' you has only to do with which way you orient the seat. It's an amazing machine. They are hard to find but when I was shopping a few years ago there was a dealer/importer in SW PA. Not cheap, but also not much competition in the NA market and not another machine here that can do what it does.
The PTO is standard 540. The only issue with PTO mounted implements, like a brush cutter/flail mower is that they will need to be mountable either front or back. Many flail mowers today offer this. I've got a 5' Del Merino flail and it's an amazing pair. It's very easy to see what you're about to mow because you're not pushing stuff down/over with the tractor, having it drag along the belly of the machine where it can tear stuff off. You do need to be aware of stubble created by the mower when mowing 1-2" trees, but my flail mower more or less explodes that stuff so there's nothing pokey left.
Here's a link to the new version of the model I have.

Down side is that these machines aren't suited for a loader. That's a big deal if you've only got one tractor.
