520H seat position

[Wayne0 1,509]

The seat is too far forward! The slider only goes back about 2 inches. Is that right or is there something wrong with it?

The bracket is all the way back on the springs. Is there another set of holes in the seat pan?

Some folks have both raised the seat & moved it back - a bit - using square tubing. Don't overdo it - your weight needs to be on top of the rear axle, not behind it.

I used 2" wooden blocks under the seat pan to raise mine.  Much better seat position and more clearance for the tire chains.

The slides WH used have only that short travel.

Our family has operators with heights from 60” to 74” so I’ve added sliders from other vendors with 6.5” travel. They also raise the seat about 0.75"

There have been some notable complications:

1. As @ri702bill notes, putting weight aft of the rear axle can negatively affect the tractor’s stability--surprise backflips become a real danger

2. The “button in the fender” style seat safety interlock becomes iffy when the operator is light and farther forward. I’ve lengthened both the spring and the plunger and added a sleeve guide to counteract this but it’s a balancing act to keep it both safe and effective. 

3. Moving the seat too far forward can interfere with the gearshift and/or tunnel-mounted motion control

I'm not worried about weight aft of the axle as there is a big a** 2 stage on the front that lives there.

Safety switch is in the seat.

I'll have to research longer sliders.

Seat switch: Then only need a heavy enough operator sitting in the right spot!

Longer sliders: one set came from a Simplicity Sovereign. Another was from a go-cart supplier. I also saw that Surplus Center once had them with a complete seat subframe.

Flag for me:
- No dimensions listed: length, width, hole spacing, travel

- fixed side-to-side postion

- potential interference with the release actuator

 

These interest me more, assuming overall dimensions and seat attachment can work. No futzing with rail spacing. Good travel.

That IS interesting! I'll have to take some measurements. The price is right!!

And the slide alignment (which is fiddly) is locked in.

This might be a better choice

I was looking for some adjustability for my 875 and 875 seat. Went to a local Pick your Part and they had a couple of riders in the pile with slotted u shaped seat springs.

Unfortunately the WH brackets are 11" apart where those are 14". I suppose I could fab new brackets, but the bolt holes don't work. I couldn't use both holes.

I'm not giving up yet. May have to drill and tap new holes.

Good find on that one! Around here they don't have that kind of yard.
