Re: helical gears

I agree with Joe on this one also...we used them in 2003 and if you use them with the gear box first supplies you better be sure to put some aluminum plates on the side. The basic nature of the shaft the gear is on is to slide thru the bearing. And if your bearing is tapered it will blow thru the gear box . Joe and Andy were also right in saying you lose alot of efficiecy due to the sliding and thrust friction....we had to have 13.5V every time we went on the field or we would run out of juice.

I would also like to recommend worm drive reducers. We used a reducer from Boston Gear this season and they are suppurb with the atwoods.
