<div dir="ltr">About rear ballast... I've held off on mentioning this until I had a quick chance to ask son Scott a question. I was recalling something he had told me some time ago but wanted to be sure I wasn't dreaming it. :-) He remembered it and said the the source was our close neighbor to the west who bought a new John Deere Compact Utility Tractor (I "think" it is about 35 or 40 HP with a nice loader and hydro-static transmission). He couldn't recall if it was something in the owners manual or advice from the dealer but supposedly he was not to install tire ballast in that tractor. They sold weight for behind the tractor or it was OK to hang an implement behind it but there was some reason to not ballast the tire or add wheel weights. I have no idea what the reason was... My first thought was that maybe they felt that the rear axles might be a weak spot but I seem to recall some mention of the hydro-static transmission. I'll likely see that neighbor this week end and I will ask him about it. I had never heard anything like that before.<br></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, Sep 5, 2019 at 5:01 PM Cecil Bearden <<a href="mailto:crbearden@copper.net">crbearden@copper.net</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

<p>I would make a small wager that your rims would have been 50%
less if you could have ordered them before Fiat got so involved in
new holland. I am just not a fan of Fiat. After they bought out
Allis Chalmers construction equipment, parts were either
non-existent or platinum... Unfortunately I have a few pieces of
Allis construction equipment here. None are operable due to a
repair parts cost of over $2000. This is the reason I went to
Caterpillar. There are enough aftermarket parts available for
Cats. Cat tried to stop the aftermarket parts supply many years
ago by buying Surplus Tractor Parts of Fargo North Dakota. 3
years after buying them Caterpillar shutdown the facility and
scrapped all the machines in order to make everyone buy new
Caterpillar machines. It did not work as they planned. The
overseas manufacturers started supplying parts and small salvages
started up all over. I recently traded my old D6 8U series dozer
for a 112 grader. My old D6 had sat for about 10 years since I
parked it. We loaded it without it not running. The fellow I
traded with is a real mechanic. We dropped the dozer off at about
1pm Sunday and loaded the grader and headed home. He had the
dozer running before dark!!!!! I wish he was closer to my place,
we could have some great times with all of our toys. That trade
has turned out to be a great deal for both of us. I have another
112 grader, and also another friend in the brotherhood.....<br>

<div>My non-antique chore tractor is a Ford 1520, which is a
23hp 4x4 diesel built by Shibaura in Japan, 1995ish. Rear
tires are 13.6 x 16 R-3 turf. It has a loader. I got it used
in 1999 with 396 hours and calcium in the rears. Rims finally
rotted through last year. Got new tires from Simpletire dot
com at Cecil Bearden's suggestion. But it turned out that the
rims aren't common. Could not find a generic equivalent, and
I had to go to the CNH dealer (Messicks, in fact). The cost
was staggering (no fault of Messick's, it was the same or
higher everywhere else). I hate to say how much but it was
deep into four digits to get the tractor rolling again. So
apparently it held off the calcium for about 23 years assuming
the original owner had it delivered loaded. I'd like to
think I'm young enough (57) to see another 23 years on this
tractor and I chose to spend the money on the beet juice.</div>

<p class="MsoNormal">Dean, I recommend beet juice.
Yeah, people say it's expensive (a relative term).
On a little sub-compact utility tractor, it might
cost a couple or a few hundred bucks. It will
probably be comparable money to the cheapest
implement you've acquired. And the thing is, it's
an "implement" that you will use every single time
you run the tractor, and it's an "implement" you
don't have to install or remove (after the initial
installation of course).</p>

<p class="MsoNormal">Here is why I think adding
rear counter weight to a tractor with a loader
helps stability against roll-over.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">When a loader is added to a
tractor the COG moves forward. With a load in
the bucket it moves further forward almost
over the front axle causing less traction or
weight on the rear axle/tires. Note: adding
ballast in the rear reduces weight on the
front axle with more on the rear. Most of the
roll over stability comes from the rear
tires. One does not want the tractor
stability coming from a rotating WFE or a
NFE. The rear wheels need to have a dominate
role. This may be an intuitive response but I
think the physics will verify it. </p>

<p class="MsoNormal">In 3-dimensional space,
the CG of a tractor is likely to be very
close to the center in terms of left-right;
closer to the rear in terms of front-back;
and some height from the ground. When you
add ballast to the tires it does not change
that left-right CG location (assuming you
add ballast equally to both rears), and
moves CG even farther to the rear and closer
to the ground. It is intuitively clear that
a tractor on the verge of a side rollover
will be aided by weight added to the uphill
side. But from a free body diagram
perspective, the difference comes from the
changes in CG rearward and downward.</p>

reason I ask is that I
replaced the tires on
a IH utility tractor
we have had since new
(1972 454). It has
over 8,000 hrs and we
have always had
weighted tires on it.
Well I didn't have
time to fill the tires
with fluid before I
began using it this
spring. So far I am
liking the less weight
for treading on wet
spots in fields. I
recently reduced the
air pressure (it was
at 25, I dropped it to
20) because it was
shaking me to death
while spraying a
field. The only time
the loss of weight has
been an issue is
moving one load of
hay--it was digging
pretty bad. We do all
of our bushogging with
this tractor so there
are quite a few banks
and hillsides to get
into. Wonder if it
would be more stable
with the fluid in?<br>
