I just checked the Solis international website and there is no mention of a tractor in the 35HP range. The Hardy Brothers Outdoors YouTube channel reported on the Fall 2024 Agriculture Equipment show which and the various Solis tractors being sold in the USA and there wasn't a 35HP range tractor. He did mention the 75HP tractors are being brought to the USA now that the EPA has approved that engine. Solis has a 50HP tractor that is sold in Europe but so far not available in the USA.
In November 2023 ITL and Yanmar formed a 'collaboration'. (Solis is the brand of tractor made by ITL.) So I suspect the 35HP Yanmar YT235 will be rebadged for ITL/Solis and maybe to Summit with a few upgrades just as Solis did with their H24 model to make the Summit TX25. Summit sales strategy seems to be to sell through Home Depot and Home/Farm supply stores to small acreage hobby farmers. Whereas Solis is selling at established tractor dealerships that sell brands such as TYM, Mahindra, and LS. The latter is where I think a person looking to buy a larger tractor would likely shop. Thus I think a 35HP Summit tractor wouldn't make commercial sense.
