Re: (ET) Front lift strap keeps breaking

Hm, my springs are still providing (much less) tension when lifted, I think they are to help get the motor started when it's down.
With 36v on the lift I have to watch it in terms of stopping before it hits the limit, but I have never broken a strap. I have torn out the stitches, but the strap doesn't usually break. Odd. 

Get one from Harold and try it.

A couple of things to check.

  * Double check the strap path. I believe that there were variations
    with the lift and “nose” piece where the strap goes over the front
    of the tractor. One of mine is a mix of parts and the strap is VERY
    close to the strap cutout in the bumper and the nose piece as well
    if I recall correctly.
  * Also check it when the blower is lifted because the diameter of
    strap on the drum get larger when the attachments are lifted. So
    what cleared at a small diameter may rub when larger.
  * Make sure that the roller on the blower is free. I had a rusted one
    that would not turn which added strain to the lift and was abrasive
    to the strap.
  * I’m sure this is not the case but make sure that you are not lifting
    it past the point that it stops.
  * As mentioned, springs will help some but they are more for float.
    When the blower is raised the springs are free -  at least on my
    tractor.

Good luck
Dean.

I didn't see a mention of helper springs. You blower does have a set,
correct?

Subject: (ET) Front lift strap keeps breaking

So far this month (January 2019), we have had about 98 cm of snow (about
40 inches).  Fortunately, I picked up an E15 the summer before last and
now have it re-powered (sealed lead-acid golf car batteries and 12-amp
charger).  Got a snowblower turning nicely and attached.  Battery holds
up to 2-3 hours of operation without getting seriously drained despite
cold-soaking (unheated storage).

Had some tire issues, but a friend recommended Green Slime.  Seems to
have resolved the sidewall crack leak, so the 40-year-old tires will
hopefully last a bit longer.  (Will probably replace all the rubber in
the summer, when working outdoors is a more hospitable.  It's cold here
this winter, even by Ottawa standards - repeated frostbite warnings.  On
the plus side, no mosquitoes.)

I wanted the snowblower going, because by Christmas the snowbanks were
already over 4 feet high, and defeating the E12 with the plow blade.

I estimate in the 15-20 hours of run time I have done this month on the
E15, I have lifted the blower 400-500 times.  (Areas I do involve short
runs and not enough space to turn around, so a lot of backing up and
transiting with the blower lifted.)  Yesterday, I broke another lift
strap.  Looks to be simple wear, breaking at the roller on the blower
frame.  I double loop to get the mechanical advantage, and the lift
motor (replaced last fall) is working a charm.  Roller sleeve and side
washers all appear smooth, so should not be fraying the strap.

Has anyone come across a highly durable lift strap?  I would just like
to carry out this replacement exercise less frequently.
