Default Tractor seat suspension for boat

I finished my seat suspension project. I like being able to do things myself and was able to put these together for under $250 each including pedestal and swivel. I had to go with Garelick pedestals because my old pedestals were Garelick. Garelick has a 9.25" diameter floor bolt pattern versus 9" for other manufactures. Anyway, here is a look at the finished product.

What seat suspension did you use? Did it somehow have something to clamp right to a pedestal? How much modification did you have to do to make it work? I may be interested in something like this. It would be nice if you could do a how to tutorial on this and add it to a sticky at the top of the page. Nice job!!

This is awesome. Let us know how it works once the water softens!

You will want a 2 7/8" pedestal approximately 4.5" tall. The pedestal swivel bolts right up to the suspension with four 1/4" x 1" long bolts. The only fabrication work I had to do was to make a plate to mount the sliding rails to the seat. You can see the plate in the attached pic. It is 1/8" thick x 8.75"x 12" steel plate. I made two plates for two seats, so I bought a plate 17.5" long x 12" wide and cut it in half.

I had to weld four M8 nuts to the plate in order to attach the sliding rails. I also drilled holes in the plate where the nuts were to be placed prior to welding them to the plate. This is so the bolts can pass through the nuts and the plate.

Then in order to attach the seat to the plate, I had to drill four holes centered on the plate in a 5 1/4" pattern. I also drilled 4 holes 1" forward of center and 4 holes 1" back from center in case I wanted to reposition the seat on the plate. I probably will never use the holes forward or back from center, but I drilled them in there.

Other than fabricating the steel plate, that's all it took.
Here is the suspension I used. It comes with a free tractor seat. It is a Darby Manufacturing - Pilot SP200/SM80X seat suspension.

Dr,
Excellent job on the seat. Any idea of the total amount of suspension that is available with this seat setup?

Also, how do you have it set for your self when you sit in the seat - with the boat stationary?
i.e. how far does the seat sink - when you just sit down in the seat?

By knowing that distance as well as the potential total travel for the seat, you can figure out how much more the seat can sink when encountering a big wave.

Thanks for sharing.

It really seems that it would be a very good idea if all of the boats in our part of the country would come with such suspension seats already installed.

Really would save on injury and body damage.

Be safe

So... your Uncle, Brother, Dad is going out to his shed this spring and finding his tractor seat gone?

Our JD tractor seats are air rides and I've day dreamed about how I could install one in a boat. Or at least the suspension part. They are really nice seats and very comfortable on fourteen or fifteen hour days. They swivel or lock, adjust forward and rear and have shock absorption front to back besides up and down. Problem is just one of them would double the value of my old boat.

Who's seat did you use? It looks all mechanical. Good idea and the spunk to follow through with an idea.

We've replace some of the air ride seats in are semi trucks over the years, I thought about these for a boat seats, you'd just need a 12volt air pump or hand pump for adjusting air pressure.
We alway buy "take outs",seats that the over the road guys don't like for some reason, $150-250 each.

I would be afraid that since the ride in rough waters will be better, you will beat the **** out of your boat more. Is this a concern ? ? ?

I have been wanting to try a similar modification to these seats as they are only $99 at Tractor Supply.
