Will the CAT 22 mower parts fit your 10? I have a 22 that has the attachment on the right side. It also has the sprocket on the power take off, the bar that goes under the gas tank that attaches to the two brackets on each fender. This is a wide gauge 22 that I've had for a number of years thinking that I might find the parts that I needed. These mowers are so rare that I don't think this is going to happen. If the part on the 22 is the one you are looking for I'd consider selling all the mower parts............Frank (408) 997-2901 The tractor is in Morgan Hill, CA

Thank you Frank for your response.
The bracket I desire is 1A9595 with the 1A8767 cap and I imagine
These were used on the 22 as well.
I will give you a call tomorrow
