The problem is that this solution isn't even close to being realistic. 28HP engines are not created equal and this engine isn't anything like the old 28HP engines from tractors of yesteryear. The tires are wrong, hydraulic drive is wrong, no PTO yet, etc. Bolting tube together on a moving machine like this, WTF. The tube works free over time as it collapses which will cause play and egging of the holes. This is completely wrong. They need to go back and study the tractors built in the late 30s and early 40s and copy those. This is nothing but a mess. Are any of these people mechanical engineers who have built Ag equipment?
