Hey mate that's looks awesome!!! Sorry I didn't respond to your requests for help . I have been busy and didn't check the web page for ages . The 23 in the B 23 means the cutting blade width is 23 inches . So your mower is an Atco Deluxe B 23 . You can check it by getting a tape measure and measuring the width of the mower . I can tell by looking at it it's bigger than mine ( my mower!) I have a B 14 . Well done - they cut really well and the clutch / drive set up is really good ( well I think so anyway !!!!
