DR field and brush mower help

[Kilo1988]

I recently was given a DR field an brush mower, I don't know much about it except how to run it. Also if this helps it's 11.5 HP 388cc Briggs motor, I think it's like a 2007. Well my problem is the part that's on the axle the makes the tires drive was shattered I imagine I hit a too large branch I just needed help finding a source for preferably aftermarket parts for this. Being that OEM is just out of my price range,
here are pics of mower an broken parts

I wish I could help but I can't.

I have an older model DR brush mower. It's got an 8 hp Briggs IC engine.

That thing will wear you out!

I have three DR Power Wagons and I find them much more useful tools. They were especially useful getting wood out of tight back yards in the tree biz. I'd load big pieces with a Boxer 320 and then run them out to the street to the dump trailer. Both are the same exact height.

Sorry for the derail but maybe it will draw other DR owners in.
