I read it used a torque converter to help it gain more power or something like that. Hope some of you Oliver guys can tell me how this feature worked? Also the pros and cons of it? My book that covers Olivers did very little to explain it.

i am no expert but the tractor was advertised as a 12-14 bottom tractor. the way it works is that when you are plowing and you hit a hard spot usual tractors would start lugging down when they can't pull it but with the lugamatic and the tractor hits a hard spot the lugamatic kicks in by slowing down the tractor speed while mantaining tractors rpms. the experts may be able to explain it better.

Way you described it is similar to a torque ampifler that IH did. And some followed with something similar. However you used a lever. Hope some more will jump in on this topic. This tractor with that feature had me curious for a while.

Here's what I found on it...


"The Oliver 995 Lugmatic has an Allison torque converter ahead of a standard transmission. The torque converter transmits the engine power to the transmission all right but it still has conventional clutch too. In high gears you can come to complete stop without using the clutch. In first gear it's hard to tell the torque converter is there. They are a best parade tractor. You can go from 0 to 20 and never shift of touch the clutch. Fun to drive. Most have a foot throttle. The 995 Lugmatic is very rare."
