Depending on what Dealer you go to, you may get a discount on any equipment that you purchase with the tractor. There was a $300 Discount for showing up to the farm show. I am not certain about financing with LS, as far as any 0% or not. But other then that, there are no currently known special spring discounts on the tractor besides what the dealer can do for you on their own.
That said however, part of LS Tractors current claim to fame is the fact that they are already at a bargain price.
