This is definitely an improvement! I was in a hurry, so I just bolted the new seat on with the 2 forward bolts. Taking it easy, I mowed for 2 hrs and the next day spent 3+ hrs with the land plane. Incredible!
Even my wife noticed that I didn't complain about a sore stiff back after mowing.
This was with the new suspension seat bolted on top of the lousy floppy bucking bronco JD 260 backhoe swivel seat mount. Now I'll go ahead and fab up a proper mount for the new seat without the swivel. I don't have any backhoe jobs coming soon and I've done a lot of backhoe work making long trenches by just turning my body sideways to work the hoe. That's faster than getting off and on to move forward when making long trenches. Maybe I can figure a mod to the swivel mount to take out the slop and lower it at the same time or lower it and anchor it down.
Thanks to the guys on GTT who led me to this seat. I wish I had done this at 10 hrs instead of 300+ hrs.
