I would try it, WollyAcres. If it's mounted, I'd probably keep the loader bucket on or add some front weights. I'm assuming your mower is mounted and not trailing or hydoswing. My mower is about 900 pounds and in transport mode it sticks straight back and handles my gravel roads in roadgear without bouncing around too much. The baler didn't push at all, which surprised me some. I wondered if it was due to the ag tires as opposed to R4. I baled before with a 50 HP Massey compact utility without a loader mounted and it pushed on the turns sometimes (tractor wanted to go straight) but never on the hills. Some of my prairie meadows are sloped and I had no problem baling up and down ... I was super careful baling sideways but it never felt anything but connected with the ground. Also baling down the slopes, you still have to back up to dump the bale and it had no problem doing that. The tractor with the loader on it is around 6800 pounds I believe. Its tires are not loaded. Thanks.
