poking a little fun (*); not "heckling". No mean spirit involved whatsoever. (hard to come across with simple words on the Internet)_
Seems like you've done some searching (so you may have already read the following) but I mostly solved my "rough ride" when mowing by running "slightly" lower tire pressure (except when doing loader work...then I run the max!)
and
Putting a seat cushion on my seat (any cheap seat cushion like you'd buy for your car) and then adding a very large sized "thigh blood pressure cuff" (bladder only) from a blood pressure cuff. Sucker must be closing in on 1 square foot.
Takes very little air pressure for you to almost be "sitting on a beach ball". I generally take it off in the winter when snowblowing (my driveway is pretty bumpless (*is bumpless a word?) and sometimes even for loader work, but anytime I mow or know I'll be crossing the yard multiple times I am sure to have the cushion on the seat. It helps keep my aging vertebrae & kidneys protected.
(*) You ask a lot of questions; some theoretical and you don;t have your tractor yet. That's why....and yes, I likely asked one or two before I had mine too and took some good natured ribbing back in the day. LOL Don't take it to heart. If I am able to contribute with any useful BX knowledge, I certainly will.
I DO ask a LOT of questions, and know how to do a LOT. I learned most of what I know from the Old Timers, those who liked to share and teach, to those who willfully listened. Don't get me wrong, I can handle a poke, a joke and a dragging through the mud. I'm not new to the internet, or too lazy to search for myself, or do for myself. For that matter, I've been doing a lot of digging and reading here. There's Gold in past topics too!!
Yes I'm new here. I'm not new to things mechanical persay. I'm coming (moving up) from a Garden Tractor, where I adapted older Cat0, Cat1 Limited, and other Cat1 bits and pieces to work on the modern. I'll say I mastered the short-comings.
Now, yep, I'm not only moving up from a Garden Tractor, I'm moving from a modern JD x739, to a different brand and into a sub-compact to boot. So in theory (mine anyway) I'm venturing into completely new territory all the way round. And this is before joining any Kubota related support forums.
With anything, questions and concerns become repetitive. That gets old, and I completely understand why.
I notice I have been asking a lot of questions. Those who want to share, will, most move on. I can also help others with solutions to issues as well.
I'll get settled in around here, then I'll really be a thorn in the heel
