Re: (ET) E-15 pulley removal -> drive belt modifications

[Andrew Poush <agp vt edu>]

Thanks again for the feedback. I have been using the notched belts changed 
at the same time according to the procedure in the manual. I even have two 
wood shims set aside just for that. 

I am using my ET to mow 8 tenths of an acre with probably only 20 feet in 
elevation change from one end to the other. Average pitch perhaps 1/10. 
Since my ET was converted to solid state controls, I find it easier to 
begin the cut in rectangular laps where I reverse back across the corner 
once at each right angle turn. After I get far enough in from the edges 
then I cut ovals where cutting only happens on the long edges. The ET is 
also used to doze snow from a level driveway of 1200 square feet in the 
winter. Plus clearing the entry into the road. So nothing that seems 
really extreme to me. How long should I expect the belts last under these 
conditions?

As long as the belts are adjusted and not old, I've had the tires slip 
before the belts. The original belts were indeed just plain V's (solid 
rubber). Bill Gunn and now me and most others have taken to using the 
notched version (the extra X) which is more flexible and sits deeper in 
the pulley. As see here

These are made for use in matched pairs, or triplets or quads - all common 
in industrial applications. Walt kindly posted the directions for 
adjusting the tension. A new set will likely need one or two adjustments 
as it settles in, then just check each spring.
