Block-up seat height

[WessAdams]

Seat height is causing knee fatigue. I have plenty of cab headroom to raise the seat base, has anyone done this? Kobota 4060 Grand HST

I did this with an older tractor. IMO the things to keep in mind are making sure your spacers and attachment method are at least as robust as the factory mounting, the seatbelt still functions as designed, and your head isn't going to be slamming into the narrower portion of the rops/cab in case of rollover

 

[WessAdams]

Yes, indeed. I am certain a simple solution is all that is required, rather than adding $500 plus for air-ride that might not raise the overall height at all. I would like the position to less low profile as a sports car, and more purposeful as a delivery van. Simplicity is always better, like the old single spring tractor seats

I raised the seat and improved the ride on my Kubota MX tractor using a suspension base. Be aware that raising the seat will make the steering wheel a longer reach. I'm 6ft tall and it feels like the tractor is designed for somebody shorter...
1-2 inches makes a big difference.

I used some 2" x 3" box tubing. Bolted it to the floor and bolted the seat to it.

My dealer installed steel 2x4 hollow tubing under my seat rails as a courtesy when I bought the tractor. When I upgraded to a suspension seat, I didn't need the steel risers anymore, but I did add 2x6 PT plate to the steel floor under the seat to raise it another 1½" instead of the 3½" the dealer did. Previous poster is right. Couple of inches makes a big difference for us taller guys.

I’m happy with the results, I’m 6’1” and still have headroom. You can see the factory studs under the flip-up seat are only about 3/4”. On the rear two I used bolt extensions, on the front I made a short plate to add two heavier #8 bolts out to the side. I did add an inner tube and used about 24lbs air pressure

 

[WessAdams]

Coupling nuts is the correct term, when I said (nut extensions). I only found two at the correct size. Therefore I made two extension plates to add heavier bolts for the front

I would have utilized a friend who is an excellent fabricator, but he is in Tennessee and I moved to Florida. Therefore I developed this fix due to availability of parts in a small town, and my limited abilities

Used 3x1/2” rubber disks to raise and tilt back the seat. New longer bolts. Surprises on how much it improved comfort.

The seats on all three Kubota tractors I've had felt like they wanted to dump me into the steering wheel. On the current tractor, I did a very simple modification to eliminate that. The front two factory bolts were discarded and replaced with longer ones. These have extra nuts to make it adjustable and lock the position.

The seat on the L4240 is a sturdy cloth instead of plastic and is more comfortable than the others were.

I used some 1 1/4" square tube under the seat mount. Of course, longer bolts. Made a tremendous improvement on the comfort level.

It seems like raising the seat is a common thing to do with compact tractors. Lots of ways to do it.
You can combine raising the seat with some rubber spacers and make it more comfortable.
Seat raising alway seems to need longer bolts and be sure to space the seat switch up the same.
Here is what I did

Hope you were wearing latex gloves when doing that as that tractor is filthy.

I would NEVER have a sweaty butt vinyl seat on anything. What amazes me is what Kubota wants for a sweaty butt vinyl seat..... Even my open station has a Cordura seat (that I cover with a hefty bag) when it's parked in the barn so the cats don't sleep or pee on it. Now if I could just break them from leaving paw prints on the hoods, I'd be happy.
