Agree that driving it won't hurt, but gee, your time is worth something--even seat time!
I drove my
BX2200 to a job about 2 miles away (In town--30MPH speed limit). Figured it would be faster than getting my trailer out of the back yard, loading up, unloading, and putting the trailer back in its spot.
I didn't have any issues with the drive, but I won't do it again. Driving didn't put any load on the engine (or very little). It was loud and BORING and I was worried about being rear ended. Had the lights on, the SMV, and flashers. Still worried about it.
And had my unit broken down or I need something else at the job site, I had no wheels to get home.....................
I'd not pay the $180, but if I had a tow vehicle, I'd spring for a trailer. My new one (5x14ft) was <$1K. A used one might be $600-800. And you'd have one for the next trip or for hauling other stuff.
Edit: After re-reading your post--if it's very hilly, no way would I drive it! Even with your SMV and flashers, if the timing is just wrong and someone not paying attention tops a hill just after you've gone out of his sight, a couple of seconds lapse and he's hit you. Granted, it would likely be "his fault", but you and your tractor might be the dead ones........... Not worth it at all in this scenario. Borrow, rent, buy a trailer, or find someone to haul it. If they are moving 50-70MPH and you are moving 6-8 MPH, the closing time is almost NOTHING!
My two cents.
