Since the deck motors are offset, for most of the time the respective cuts overlap. Square blade ends appeared to be the key.

However, the blade drives were belted together. The belt was set so that the blades were always at right angles to one another. That is, they were timed so they'd never strike each other when rotating. (I guess you hope that the belt doesn't slip.) When you have 2 independent motors driving the blades, as in the R36 / ER8- 36 and E8 / E10, you can't time them that way. You have to find some other way to ensure that the blades will never strike each other. The ways I can think of to do that are by allowing clearance between the blades, or by setting one blade slightly higher than the other. If you offset them in height, the cut will be uneven. Not so good. If you allow clearance between the blades, you'll have some amount of grass that's missed. That's not great either. Maybe it should only be a few mm, but there has to be some. If you have an E15 or E20 with a 3-motor deck, the center blade is farther forward. It can (and IIRC does) overlap the others' cuts horizontally. That eliminates any gap. You don't have this on a 2-blade deck such as the ones on the riders and the small-frame tractors. Now, it may be that my R36's blades are indeed too short. They're what the mower came with when I got it I've been assuming that they were standard factory issue, but I bought the mower used, so who knows for sure? Maybe they're aftermarket blades. But they always leave an unmowed stripe an inch or so wide in the middle of the deck. So I overlap cuts about 55-60% when I mow. Really? Nobody else with an R36, ER8-36, or E8/E10 has this problem with the mower leaving an unmowed stripe down the middle of the deck?
