There is no model 20832, do you mean 20382? If you did mean 20382, you have a lot of differences.
20382
1. Cast deck
2. Better transmission
3. Better drive wheels
4. Adjustable handle.
5. Better mulcher
6. In my opinion, far better mower for the price. I tell people interested, if you can afford it, always buy a cast deck unit. Unless you are very partial to the Honda engine, I would recommend the model 20381.
