Need Seat repaired/repalced on Branson 4820C

[Gregster613]

Looking at just the suspension, the bolt pattern on the base plate is 4.5 x 8" (probably in centimeters) but this is the real measurement for what is needed at the bottom of the suspension or a whole seat. Replacing the handle may not be an option, because I cant figure out how to reset the spring tension to reinstall a new one? Thoughts and thanks to everyone helping!!!

Couldn't you just reset spring tension via trial & error? I dunno for sure but it seems like that is possible to me.

The only thing you have mentioned as being broken is the adjustment knob and/or the pin that secures it. Is something else broken? Have the springs detached?
Otherwise, why can't you put on a new knob of sorts, and tighten it down the rate of tension you desire?

Resetting 300lb springs and putting your fingers inside the suspension sounds like a great way to lose some fingers. I don’t have a setup to make this happen. Plus I would love to find a replacement instead of the $$$$$ Branson seat.

The plastic adjustment knob can be replaced with a metal knob. It's held onto the rod with a spring pin.


This is what I replaced my original seat with: KM 350 Utility Mechanical Suspension Seat Assembly | Tractorseats.com

So the springs have become disconnected? If you loosen the adjusting bolt all the way, might you be able to reconnect the springs?
