The 620 has black trim and decals. The 720 has white trim decals. Also on the "dash" it should say 620 or 720. Also I find the 620 leaks and the 720 does not (ha). 1. The URL link below goes to a 620. 2. The optional image link is of a slick 720 in Ohio (JeffG).

Thankyou for the reply, I found out I am AC stupid - HA HA. By reading the AC history on the internet I have a 4040 so any information on a 4040, I would greatly appreciate. Thankyou, Jim

To the best of my knowledge, the 16.5HP AC616 is equivalent to Simplicity 4040, the 19.5HP AC620 is equivalent to the Simplicity 4041, and the 19.5HP AC720 is equivalent to the Simplicity 9020. The AC616/S4040 have Onan CCKA 16.5HP motors, and the AC620,AC720,Simplicity 4041 & 9020's all have Onan CCKB 19.5 motors. All these tractors use like attachments. Cat"0" 3ph, front hydraulics, & 2000 RPM rear pto were options on AC616/620 & Simplicity 4040/4041 but Standard Equipment on AC720 & Simplicity 9020. Some tractors may have been upgraded over the years. I have seen a Simplicity 4040 with a Onan CCKB 19.5HP, but it was apparently a replacement engine. They are interchangeable.
