First off, hello everyone. Just signed up with the hope you can shed some light on what I have.
I picked this gem up off of Craigslist. Runs ok, doesn't seem to want to run much below 1/2 throttle. It is a 46" cut with 20.5hp Kohler engine. Hand operated hydrostat with a spin-off filter on the transaxle.
It cuts very good and I was basically using it as a weed eater with wheels earlier today cleaning up a bank. She is going to be tortured more than anything if she hangs around long.
The steering system seems to have some issues. I believe it is a combination of the drag link being rigged back together and the bushing being worn out in the front axle pivot. It will almost turn in it's wheel base to the left but won't hardly turn around in my one acre yard to the right. I'm going to try to come up with both of those to put back in it and see if that helps. I'm also planning on filling the tires with washer fluid to help add some traction. I have access to a tire groover so I may also consider taking out every-other set of tread blocks to give it more of an ag-tire grip. It has the 12" wheels so old 4-wheeler tires are also an option at this point.
The part number under the seat is 917.251522. It seems to be yet ANOTHER odd ball piece I have managed to drag in as I've had issues finding manuals for it online and wound up spending near $20 on one from Sears Parts Direct so I have some idea how to service the transaxle.
Anyways, thanks for any help you can provide!
