66 HP Deutz diesel bolted directly to a large hydraulic pump. That pump drives several different motors/rotors. You can see it in the pic above the cutter wheel. The motor has a splined gear that drives the poly belt. The teeth/cogs on the belt are at right angle to the direction of rotation. The cutter wheel end is a shaft/pillow block bearings with another splined gear. The smaller wheel end is supposed to wear faster than the drive end. It goes around more times but, I'm 6-700 hours on a gear set and it looks like the drive gear is 50% worn and more like 10% on the other one. I try to buy the parts peak season so I have them on hand when I need them.
This set up is frowned upon because of the higher rate of parasitic loss compared to the 2 belt setup. I have read the loss is somewhere around 25%. Knocking my 66 HP down to 49.5 HP at the cutter wheel. The advantages? Less belt maintenance/replacement? Not sure, the only two belt unit I've run is my tow-behind. I have not used it enough to justify owning it.
