6 inch Transmission pulley

Recommended Posts

dentwizz
Has anyone used a 6" transmission pulley on the 3 speed chassis? If so, what is the belt length to fit it? I seem to have thought there was a chart a while back but I couldn't find it in the search.

throw a tape across there and it's actually like 6 1/2" pulley. i have seen the 8" and 10" factory simplicity pulleys but never a 7". do you need a 6" pulley ? . i was thinking of going with a little larger pulley on my mowing tractor to slow'er down a little.

If you are using 1/2 inch belts, then get some 1/2 inch rope. Wrap it around the pulleys tightly like you would want the belt then mark both ends at the overlap. Straighten the rope out and measure between the two marks. Done this many times. It usually gets you within 1 inch of the belt size. I have had to return a few belts and go either up or down one size. At least you are directly in the area of right size. If you compare the sizes listed in the chart and there is a close match to your measurement, then you know the correct size.

Once you figured out your belt length for a particular driven pulley (leaving the drive pulley always the same), the change in driven pulley to belt length is easy. For instance to change from a 5" driven to 5.5" driven will require a 1" longer belt. To from 5" to 6" requires a 2" longer belt etc.

Me too :D:D I'm thinking if you cut the uprights off between the bolt holes, than add a short plate to the sides to act as a pivot, they could actually work for the seat pan :O:O:O

        Over a year ago, you answered a question I had about the tool bar for my FDT. In your reply dated Dec 31, 2019  you said the spacer, part #16, goes in the bar to allow for up and down depth adjustment. does this mean the bolt has to be tightened at whatever depth desired or does the bolt slide up and down, allowing the lower hitch to free float?
         If it is tightened so the lower hitch and the bar are rigid, then is the depth to be controlled by the shoes? Or by the lift handle?
        Is there any kind of user directions for the tool bar? The Outdoor Power Manual basically shows how to assemble the bar but not how to use it
