The
L2501 has a significantly larger engine that is also underrated by the factory to fall below the 26HP threshold for no DPF. It also has direct injection vs the Summit indirect injection. The 2501 has more PTO power and is rated at a lower engine RPM. It has a larger fuel tank, and significantly larger tires, and weighs a little more. The 2501 has a longer wheelbase and the loader lifts nearly 10" higher. It has more hydraulic flow. One of the biggest differences is the transmission. Summit has a crappy two-range hydrostatic while every Kubota except the very small entry level BX series has a 3-range. I think the Summit is more comparable to the large B series frame Kubota, now called the "LX." Its a cheap tractor that is trying to sell on being feature rich and having a decent warranty. There are always tradeoffs when you buy something that's cheap. Summit has to buy the tractor from ITL, pay to have it shipped over here, pay the middleman retailers like Home Depot to carry it and advertise it, and pay the service facilities they have made arrangements with. In order to do all this and still undercut the competition, they have to cut costs somewhere. So the average non-savvy buyer sees the machine at Home Depot, it has some fancy projector headlights on the front and features like the 3rd function and rear remote and leveling loader that the mainstream guys either don't have or you pay more for...and see the price and think "I want that." But anyone who uses a tractor commercially is not going to want this. And contracting out with an automotive repair facility for service is not quite the same as a JD dealership with all the special tools needed for complete servicing along with years of experience of working on these machines and a complete stockroom full of common parts vs Joe's Garage that primarily works on Ford's and Dodges but can squeeze in a Summit tractor that needs a seal on the PTO shaft replaced but has never done one before.
It seems the new model for introducing products into the US marketplace is now you contract out with some Chinese or Indian company who is already making basically what you want...you give them some specific features or specs your version needs to have, plus colors and sticker graphics...set up a basic distribution plan in the US with some method of attempting to service these things as needed...and sell it as a premium product. Northern tool has been doing this for years with their Chinese made NorTrac machines. Granted, this Summit tractor looks better than the NorTracs, but frankly if I wanted a cheap foreign tractor I'd just order the kit online, assemble it myself, and gamble on getting parts or being able to fix it myself and probably lop off $5k or more.
