Are you thinking 1" spindles into a 3/4 axle hole?

They are 7/8 spindles. From a 1054.

I have three gt14 front axles laying here. Wish you were closer

Thanks Richie, I thought about getting a 953 or similar axle but the one I want to use is 2" longer and only has a 3" drop. I think that axle would make the frame too high? I may have to build an axle to get the width I need.

@19richie66 would you happen to have any steering arms that would work with the Ross steering?

Not that I’m aware of.

you know, the non-Ross 953/1054/GT14 steering gear is pretty stout as well.  Once I begin rebuilding mine, I think I’ll swap over to that steering vs traditional

How about something like this?

This what I was thinking for getting around the big tires and under the frame for the engine up front.

Use new heim joints for the tie rods

Wasn't there a large dump truck build started at the 2022 show?   

Yep…

That looks complicated. I think by raising the frame and a wider axle then maybe incorporating your heim joints that may work.

I thought this was to be the 2023 raffle tractor.    Any update on the status?

 

 

[Sparky-(Admin) 21,315]

  I heard the same thing about it being the 2023 raffle rig. Maybe it wasnt completed??

[JPWH 6,033]

I laid out the build on the shop floor and the frame is going to be +/- 8'. I ordered the 2x2x3/8 angle iron for the frame today and dug around on the metal storage rack and found a piece of 2x3x1/4 tube steel to make the axle and some round stock to make the spindle and axle pin supports. I may get started sticking metal together this weekend.

I'm still torn between low and hot roddie fast (35-40 mph) or big powerful with lots of torque and slow. Maybe UTV type with some tube frame ?????

 

8 ft is a long one. You'll need to position the Ackerman angle for the steering arms correctly so it tracks and steers right so it helps with the steering radius.

There's lots of crazy math out there for it but go by this simple diagram and it works great for our low speed non space shuttle tractors.

I'm going for 2 seater garden tractor that looks like a dump truck. The wheel base should be about 6'. I'm going for a 3x5 dump bed but I'm short legged at 5'7" so it may shorten up a little.

I don't have a supply of parts tractors so the tires may need to be sourced new. Maybe dual ags and tri ribs.

I was checking out the Ackerman angle and was intending to use the diagram you show as a starting point and go from there.

[ebinmaine 67,420]

At low speeds it won't hurt much to have the wheelbase a touch too long for a given Ackerman angle. 

Our long wheelbase semi  trucks are a prime example.  

 

At. Low. Speeds. 

 

When I'm turning very sharp into a parking spot or driveway the front of the trucks definitely scrubs some. Unavoidable.  

 

That scrubbing can be negated some on a tractor by making the front wheels tilt out at the top a few degrees. 

I found that on some farm tractors and built the spindles for Colossus that way. 

 

Using a tri-rib tire will also help a fair amount.

These old Toro Golf coarse tractors were cool

 

But somehow mine will end up looking something like this

Nothing about that picture is OSHA approved!

Here in Hill country those letters have a slightly different meaning:

 

Only Safety Hazards Allowed

 

 

But... on the other hand it appears they have a fairly decent, 

Overhead Safety Hazard Avoidance 

System in place.

Trail cam at @Pullstart's in about 30 years... he's gone full native and doesn't even wear his steel toed flip flops anymore... 

 

[Pullstart 62,834]

@SylvanLakeWH if I were to go full native, there would be a blurred center section.  At least he’s got his safety skivies on!

How did I know Kevin would be dragged into this 🤣

Can’t be my charming smile @c-series don!

Why did I get involved with this thread? Now you got me wanting to stretch the D and put a bed on it.   If I did that though, I could lower the 3 speed transmission in the frame and use a belt on the front and a small driveshaft to the rear axle.

So your upping the game with a tandem axle? Go for it I'll follow along.

Tandem. Follow.

Good one!
