I bet I have a brochure on the 2320 and the 2620. I will start to look. thanksLooks like you have 23Hp engine and 18Hp pto. So I think the closest models would be the B2320 or B2620. Looks like yours is in between the two. Note if you start comparing the 2320 to the 2620, they do have different tire sizes and stances and the loader models are different. In other words, its not just HP difference.
