to tall?/
This crawler must have been designed for a short legged man. Any good way to get more leg room?? I've been thinking about raising the seat. Anyone done that or??? It's all the way back plus a little and pinned.
Which crawler, which seat?

look at pics 1 and 2 this is how my 2010 is done not sure how a 420 is mounted hope it helps http://www.jdcrawlers.com/messageboard/ ... highlight=
2010 with 622 dozer with mod. 35 ripper and a 2010 with 622 dozer bought in 1969 and a 2010 loader with drott and mod. 36 ripper
That is a tractor rockshaft on a crawler, not sure how that would compare in position to a crawler rockshaft. Only option there is to make spacers and move the seat slide up and back.

Hi,
Yes, looks like a 420w rockshaft. That would put the seat mounting something like 3" closer to the dash compared to where the seat brackets put it.
I know because I had an extra 430w rockshaft and was thinking about putting on my 420c. I made a bunch of measurements and came that conclusion.
I know that the stock 420c brackets put the seat in the same place relative to the crawler 3pt lift arm unit.

No, the seat is on the original frame in the original position. It is slightly further back on the rails than the original pin holes allowed. Yes that is a tractor rock shaft set up and the seat is quite a ways back over it. The seat was positioned normally and the rock shaft/adapter plate was built to fit under it.
I think the simple thing is to do as Lavoy says and build a couple risers. I will have to do some trial work to see how it affects the hand controls. Might need extensions on them too.
This shows the seat frame and original seat brackets. The 3pt operating cylinder is under the seat.
For a quick simple riser, you could put four short pipe nipples under the slide to see if vertical height is enough. If not, then I would use some 1" box tubing to move the holes back as far as you need, then put risers on from there.

Hi,
Ah. That pic angle is a lot better. I see what you made happen there. Neat.

You gave an idea. I could just slip some 2X4's under the bottom cushion and get a feel for it. When the height feels good, measure and make permanent risers. I tend to think going up a few inches should make a lot of difference.Lavoy wrote:For a quick simple riser, you could put four short pipe nipples under the slide to see if vertical height is enough.

420's with 90 loaders actually had about a 3" rise done with wood from the factory.

That's what's sitting outside for my next project. I'll take a look at it. I got in on 5 pallets and one big chunk and I haven't gone over it that closely other than to make sure I got all the parts.Lavoy wrote:420's with 90 loaders actually had about a 3" rise done with wood from the factory.

No blocks. I went out and looked at the seat frame and pile of parts. Could be they were tossed but the seat frame is near perfect.
