Doggone-it ... I went out out to do some more work on the Bean Cutler today but this hard steering on the Ridemaster cart is bugging me and I can't concentrate.
So I'm going to do something about it. .......

I decided to make a reducer sprocket assembly to fit in-between the steering wheel and the front steering sprocket on the tractor.
I turned up a hub to fit in the large sprocket and it has a counter bore that the small sprocket will fit into.

These three parts are then all put together and welded up.

Posted Image


Another hole was drilled in the frame in front of the shifter control.
The hole in the frame behind the shifter control is where the steering wheel was mounted.

Posted Image


The reducer sprocket has bronze bushings in each end and fits on a 3/4 inch diameter shaft.
The shaft goes down thru the hole in the top of the frame and a bolt comes up thru the bottom of the frame and threads into the shaft to keep it in place.
Here the sprocket and shaft are mounted on the frame so I can mark where to cut the shaft off above the sprocket.

Posted Image


The reducer sprocket is painted and re-assembled on the tractor and the steering chain is shortened and fastened back in place.
The shaft is drilled down the center and a hole is drilled in the side to line up in-between the two bushings.
There is a bolt and washer threaded into the top of the shaft and it has a grease fitting in the head of the bolt.

If you look close, you will see a yellow plastic plug in the hole where the shaft for the steering wheel was.
I figure that as long as I'm going to all this work, I may just as well move the steering wheel so it is more in front of the driver.
This will make it easier to grip the steering wheel with both hands.

The chain from the front steering sprocket runs to the smaller reducing sprocket.
The chain from the steering wheel will run to the larger reducing sprocket.
This will increase the gaer ratio between the steering wheel and the front steering sprocket and make it easier to turn the front wheels.

Next is to make a new mount for the steering wheel.
With the sprocket reducer mounted solid on the frame, I need to make a way to tighten the chain between the steering wheel and the reducer sprocket.
The original chain tension system is designed to tighten the chain between the two sprockets.
I want to make the chain tension the same way between the steering wheel and the reducer sprocket instead of using a third sprocket on the side of the chain.

I have a piece of 2x2 square tube that is 5/16 inch thick and a larger piece of square tube that fits nicely over it.
The original shaft will be used for the steering wheel and a threaded rod will be used to tighten the chain.

Posted Image


Holes are drilled in the larger outer tube for mounting the steering shaft and a slot is milled in the top for tightening it down once the chain adjustment is made.

Posted Image


A piece of metal is welded inside of the 2 inch tube and this is drilled and tapped for the adjusting screw ( you can just see half of the hole down inside ).
I cut a square piece of steel that fits on the end of the larger outer square tube.
A hole is drilled thru it and the adjusting screw is put thru it.
A washer and nut is threaded up on it until it is just snug against the steel plate.
The nut is then welded in place so it can't turn.

Posted Image


The adjusting screw is threaded into the 2 inch tube until the outer tube is slipped all the way over the 2 inch inner tube.
The hole for the tension bolt is drilled and tapped.
This allows 5/8 movement in the outer tube to adjust the chain tension.

Here's how it looks so far with the steering wheel set on it.

Because the chain from the steering wheel runs to the upper sprocket on the reducer sprocket, the steering wheel has to set higher now.
The end of the mounting bracket is bent down to where it will attach to the frame.

Posted Image


The new mounting bracket for the steering wheel is tack welded to the frame.

Great fabrication work again today Ray. Question though, what is that lever and does it still have room to operate?

Looking fantastic Ray! That's a pretty intricate angle combination on that piece of square tubing! Impressive to say the least!

The lever controls the cable that operates the hydrostatic transmission and yes, there is plenty of room for it to work.

The new mods on the "Limo" are fascinating Ray. You work progresses so fast that it seems I have to check in every couple of hours to keep from getting too far behind.

Looks like you are well on your way to curing that issue Ray. Should make it easier to turn for sure. Nice addition.
