Just got the new 2601 and I had my son in law do the first mowing as I had other chores. About 2 hours later he came back saying "that's the worst riding tractor I've ever been on". Later I had a chance to finally use it. Wow was it a rough ride. However i had been through this on my old B2410. We need the AG style tires and the dealer had them inflated to almost 50#. I quickly reduced the pressure to 32# and now it feels like the tractor I did have. So much better. I don't know how low you can go on pressure, safely, but never had a problem at 30 to 32 # before. If you do this just pay attention to your tires because you want to be safe. Maybe someone else has also done this or knows what you can run on the low side.
