Back to the original question. Why not ask directly the manufacturer ?
My name is Arie Prilik, and I'm the sales manager for MTZ / Belarus tractors.
All our tractors are fully compliant with all emissions regulations. Canadian and USA government allowed certain quotas of Tier 3 engines, and we're just lucky with our timing to have some quota tractors left. Once gone, we're switching to Tier 4 with DEF, like everyone else.
So indeed, it's a last chance to buy a new Tier 3 engine tractor (no DEF, no DPF, no complicated electronics, no computers, purely mechanical design).
Very limited number of tractors are available: 84, 105 , 122 and 155 hp sizes. Warranty up to 5 yr/ 5,000 hrs.
To those who are not familiar with MTZ/Belarus (world's largest tractor manufacturer) , we'll be happy to connect you with happy farmers operating 20-30 year old Belarus tractors with 15-25,000 hours on original engines.
