They are well made, and very functional BUT, they orient the output shaft and its seal pointing downwards along with the vent nut at the lowest point on the gearbox. Yes, there's a vent nut. It's a small hex head thingy with a tiny hole in one of the flats. Over the winter, my deck lost most of its gear oil out that vent nut, all over the raised wood floor of my barn and making a huge mess. When I questioned Larry, and got a prompt reply of, "Yes, I've heard of that happening with others....." So we have a product that MAY result in nearly all of the oil in the box to leak out all over your spotless concrete or wood floor. Is that good? If there was a warning or something to alert us to that fact, at least I'd know what to expect. Because I like the rollers, the fix or workaround I came up with is to A) drain the gearbox oil out at the end of the season. (not a bad idea to change it yearly except you have to remember to put it in before the first mow! B) Remove the mounting bolts that hold the gearbox in place and turn it 180, so the output shaft and the vent nut are pointing up. Both are a pain when it has turned chilly, and the only thing you want to do is get the plow on the tractor, and go in and watch the game. Personally, I'm opting for B. Great idea, poor execution IMO.
