riding mower repair question
 
The front axle on my JD LA175 just broke in half.
It's not really an axle in so far as it doesn't turn.
It has sockets for elbow shaped bars that hold the tires.
The two rods connected to a plate at the base of the steering column pull those elbows to move the front tires.

So this is just a cast iron bridge-shaped piece.

I found the part online for $50 and I'm thinking of trying to swap it out myself.

It's tight quarters under the mower, and I couldn't tell on first inspection if the motor would have to come out to do it. It looks to me like there is just one bolt running through the center of the axle that holds it in place on the frame.

Has anybody else done this? Is it worth the risk or should I have JD pick it up, fix it and return it (surely for a lot more than 50 bucks).

I have never actually had to change a front axle on a lawn tractor, but have worked on enough of them to be comfortable in saying yes, I believe that there is only one bolt holding it in place. I cannot imagine having to remove the engine, or anything such as that. I would raise the front of the tractor, preferrably with a floor jack, but a lever and fulcrum should suffice if necessary, and block the front end off of the ground with a beam or jack stands positioned behind the front tires, ensuring that it is safely supported. For $50, it's hard saying what you would get, whether it has the hubs on it, or is broken down at the spindles, but it should be pretty straight forward either way. There will be some manner of stop, so that the axle can only pivot so far, so compare the old axle and new axle before reinstalling it, to make sure that you have all of the parts in place.

Should be a pretty simple job. I'm not familiar with this particular model, but most models are very similar. On models I am familiar with the axle always comes out from the bottom, so the engine would not be in the way. You will have to remove the mower deck (very easy) and then lift and support the frame of the tractor though. Here is an exploded view from johndeereparts.com
