<font color="blue"> the ideal tractor would have to be bi-directional, </font>
Yep, I couldn't agree more. Some things are just better out back, like plows and disks and maybe the tiller, if you have long areas to till...with the exception of flower beds, where I believe a front mounted tiller is better. And some things are better up front, like mowers and FELs, snow moving equipment, etc... there really is no one machine that does it all to perfection, but there are some that come close to doing most things well. As I've said before, if you need to do field plowing, discing, things like that, a conventional tractor would suit your needs better. But I really think the Power Trac design is superior to a conventional tractor of the same size for most things that I do, like mowing, snow clearing, FEL work, brush hogging and switching implements very often.
The Compact Tractrors Are Designed All Wrong thread is a great read.
<font color="blue"> The small tires on the Power Trac and the low profile are great for mowing on slopes, but the lack of ground clearance would cause problems. I would bottom out in several areas. Also, the small diameter tires will not provide as much traction as large diameter tires</font>
The full time 4WD seems to be pretty effective so far, even with turfs. And I haven't had any ground clearance problems yet. Of course, you have a much larger tractor than I, so it is hard to compare apples to apples. Maybe a comparison with
A larger Power Trac would be better.
Click on the picture of the tractor when you follow that link and also
click on the attachments link there. They also make smaller and larger models.
<font color="blue"> Also, I don't see any offset mowers for the Power Trac </font>
There is a gentlman on the Power Trac forum
(read this thread) that tows two 57"
Kunz self powered mowers and runs the 60" Power Trac mower on his PT425. That's around 13' of cut... not too bad. For steep banks, he drops one of the mowers and hangs 57" over the bank. Still not too bad.
<font color="blue"> I admit I may be just trying to do too much with a single machine. In retrospect, I probably should have just bought a good ZTR for the mowing and then an old used tractor for the heavy stuff, but I was trying to avoid buying anything used because I wanted something I could just put to work and not have to work on.

That is the hard part... trying to find the single machine to do everything you want to do and sticking with a budget. Sometimes it can't be done. In my case, I'm completely satisfied with our purchase.
