I asked about this the other day but I'd like to see a bit of discussion if possible. It is important because the price difference is nearly $2000 Canadian if I want the 25. They both go 5 mph. And I assume both bag grass the same, because they both have the identical grass fan. (I may be wrong). From reading way into back threads, they have similar gas mileage. Is it truely worth the price, if I will be using a 48" and never a bigger bagging deck? Thanks!
