Re: (ET) Adjusting blade springs?

[Mike Finck <M Finck setterlin com>]

In my opinion the speeds are not great enough to cause damage transferring 
a solid hit through the blade onto the chassis.  I have put a piece of 
electrical conduit (EMT) not Rigid, through holes already existing on the 
spring side of the blade.  If a great force was encountered (an immovable 
object meets an irresistible force) the conduit would deform absorbing 
some of the shock.  Mine has been this way for 3 years.

Subject: (ET) Adjusting blade springs?

We've had freezing rain and snow dumped on us here the last couple of 
days, and I've been out in some of that pushing the slush around.  This is 
the wettest stuff I've ever tried to plow.  I found that I had to run the 
E15's dozer blade at 45 degrees and push only about a 6" wide strip at a 
time, or the blade's release springs would dump it.  It took a LOT of runs 
down the driveway to more-or-less clear it out.

Anybody know how much I can safely tighten up those release springs?  Is 
there any specification or way to measure how easily the blade should 
deflect under pressure?  I don't want to risk bending the ET's chassis, of 
course.

Thanks.
