![]() We’d run 10 gallons of gas through the 35 Wisconsin and saw 1,500-1,750 bf. That is, we’d run 5 gallons of gas through our 20 hp Onan to saw 1,000 bf. But you could really use the power with thicker blades with more set on larger logs. I’d say the 35 hp Wisconsin used about twice as much gas to produce maybe 1.5 times as much lumber as the 20 hp Onan. We also had a 94 model with an 18 hp B&S gas engine that I changed out to a 20 hp gas Onan. The 96 Supers didn’t have the faster hydraulics, better clamping system or computer setworks of the newer models so I’d expect it to perform more like a new Standard LT40 with the 36 hp gas engine. ![]() We had a 96 model LT40HDG35 Super with 35 hp 4 cyl Wisconsin gas engine. The engine was a 4 cylinder 36 hp Nissan. According to what I observed the 36 hp would use about 3 to 4 times as much fuel as the 24 Onan in a day's milling. I noticed the fuel tank level dropped drastically. They cut about 4 or 5 small pine logs and the mill was started and stopped numerous times during the demo. I went to a demo of the mill with the 36 hp engine. Sometimes you can keep upgrading and adding options on things without really making a difference in performance. I would like to be realistic in the amount I spend but also would like to have a relatively high production mill. What engine do you have on your mill? How much practical time would a Super WM 40 save over a Standard 40 hydraulic, say cutting 4/4 lumber? Also, how big a deal is setworks or computers on a WM or any other mill for that matter? Does it really add to production? It was well below freezing but it started right up. Here is a picture of one of the 36 hp gas (Nesson, I think) we looked at while in Indy last winter. When we wanted to upgrade to a new mill, the LT40HD standard with 36 hp gas motor was our second choice if we couldn't work out 3 ph availability problems. Both should cut at the same rate but the Super would have faster hydraulics and faster head travel, board dragback, and a few other features. If you want the power without the cost, this combination would save thousands over the diesel engine. Wood-Mizer offers a 36 hp gas engine on their LT40 Standard mill and their LT40 Super mill. How much difference in productivity is there if that was increased to a higher HP diesel? Considering that there is a big initial price difference between them, does it make a lot of difference to go to 37 HP or 42 Turbo? come standard with about a 25 HP gas engine. Most of the fully hydraulic mills that include log handling, etc.
