Firstly just because the model numbers are different it does not mean the mowers are functionally different.
Hidden in the model numbers are all sorts of codes for colours, headlamps etc,etc.
OTOH the local dealer looks at what the factory is making , then decides what is likely to sell in his area the orders the mowers.
The big box head office just tells Toro to supply them with 200,000 48" mowers for $2000 each delivered or they will buy them fron China and Toro will miss out this season.
It is then up to Toro how they meet the price ceiling or weather they will take a profit cut in order to get the volume through the factory.
So some times they will be the same and some times they might have old worn out press dies which they can use with thinner steel to make what looks like the same product once painted with extra thick paint.
Trouble is unless you are on the shop floor of Toro you will have no idea till things start to go wrong so in your case you will be making a 10% lottery, feling lucky ?
From the dealers stand point, he has paid $ 3400 for the mower and out of that will do the in warrantee service & predelivery service and purchase stocks of spare parts plus any special service tools or training required .
The big box has paid $ 2000 for the mower so is making 3 times the profit he is without doing any service on the machine at all and he will be expcected to do all the warrantee service on the mower he made no profit from selling.
Even worse, in most cases the dealer looses money on warantee service and has to put up with all the agro from customers who think they are getting a raw deal.
Some dealers take this very personnally thus treating big box customer like thieves the pages of this forum are full of those cases.
I am not saying that all dealers are angels, some should not be allowed in the business .
As for the different set ups , I have not worked on enough of them to have any opinions but the whole set up of the steering wheel models is really complicated and I can see a lot of fun when they get a few years old and start to wear.
There will be absolutely no difference stability wise on slopes between the lap bars & steering whell set up.
The problm on hills is all because 80% of the weight of a ZTR is on the rear wheels so they do not benefit from the wheelbase of a tractor type mower.
In order not to tear up your lawn the tyres fitted are no where agressive to maintain traction on slopes.
