The tech is full of it. You are supposed to start ANY of their tractors at full trottle, and never at 1/2 or 2/3. A shock to the belt? That's the first I've heard of that. Someone correct me if they have proof I am wrong. The techs I have had out said to start it on CHOKE, and then immediately turn it to full throttle.
Did you know that Sears is so cheap (as is the probable mfr. of your tractor - Husqvarna), that don't design the decks to allow for any ADJUSTMENT for belts that have notorious problems with stretching out. How simple a fix it would be to have a simple adjustment mechanism where you could compensate for a belt stretching out. But, no, they don't want to spend the dollar it would cost, plus this lines Sears' pockets with frequent belt purchases and technician install fees, if the customer is not capable of changing the belt himself. I've left messages with the appropriate people at Husqvarna about why they design their tractors with flaws such as this one, the horrid mulchers, and the hood designs that shake all over the place, rubbing the paint off the bottom sides of the hood, where it sits in the plastic grills on my 20381, and cuts grooves in the plastic housing behind the steering wheel, where the deck also sits and moves to cause this problem. By the way, Husqvarna never returned any of my calls. That speaks volumes.[/QUOTE]
Ok so let go over this one point at a time.
First point. Sears makes absolutely nothing. All they do is sell it.
Second point. Almost all engine manufactures tell you to start engines at 1/2 or 3/4 throttle. My Kohler says 3/4 throttle. PTO is suposed to be started at 3/4 throttle as well.
Third point. Belts do not stretch they wear on the angle sides of the belt till they are so thin they bottom out on the pulley
Forth point. If you sent me an email with stuff like this in an email I would not respond either. I would not even know where to start. You are so angry about stuff that you have not educated yourself on I could not imagine that anyone would want to correct you in fear they would get a worse name for them selves because you did not understand them.
Fifth point. It makes them smart to not take you on as I don't think you would care if they explained it the way I have.
I also expect you to get really mad at me for posting this. But I truly don't give a flying _____ what you think.
Very last thing. I will not offer any type of proof in my statements because a simple google search will give you all the proof you need and probably don't want.

Did you get a PhD in how to be nasty, degrading, arrogant & abusive? In quoting you, "But I truly don't give a flying ____ what you think," I return it as a statement right back to YOU.
(1) As a new member, to receive a post as nasty, critical and confrontative as yours, is beyond what I would expect from an adult with any sense of decorum or decent behavior - You have NONE.
I don't need your insulting, disgusting and condescending replies - so, DON'T RESPOND anymore.
However to show the nonsense of what you posted, I give the following answers:
"Almost all engine manufactures tell you to start engines at 1/2 or 3/4 throttle. My Kohler says 3/4 throttle."
I did a search on Kohler engines, and extensively looked at Kohler's site. NO WHERE do they address starting their engines at 1/2 to 3/4 throttle. You must enjoy spouting off fabrications you made up. I'll be calling Kohler next business day.
And, in my Model 20381 Craftsman tractor's manual, it instructs you to start it in CHOKE position, which is full speed, the same as full throttle. That is for a B&S 19hp engine.
WRONG. I did a search on "should small engines be started at less than full throttle," and nothing comes up about starting throttle speed. However, most results definitely recommend running them at full throttle for LONG ENGINE HEALTH.
www.practicalmachinist.com - Quotes:
Jaledu - Years ago when I worked as a mechanic in a small engine shop we would always instruct the customers to run their equipment at full throttle when mowing. Some engines would simply overheat when put under load at lower RPMs. They need that flywheel spinning faster to cool down the engine block.
kenh - These engines are most efficient at full throttle.
Also cooling is a factor.
John in MA - Don't forget splash lubrication--lower speed=less splash. The blades also give the best cut at speed. Better lift, etc. They'd run blades even faster than currently done if it wasn't for safety regulations. When small engines are running at top speed without a load they're actually not using much fuel or generating much heat at all. The thrtottle plate is almost closed. It's only when you load them that they start opening up. Lower speeds frequently aren't even governed, so you can't get much done.
I'm not bothering quoting more; this is more than sufficient.
Doing a Google search on, "Do tractor drive belts stretch over time?" Shows almost every response if that they DO indeed stretch. So much for your claim,
"Belts do not stretch they wear on the angle sides of the belt till they are so thin they bottom out on the pulley." NONSENSE. I & thousands of other Craftsman owners have had their drive belts STRETCH, not thin. I can attest the belts on my Craftsman tractor did not wear or thin, as you claim; they were perfectly square and not worn on the sides - simply stretched enough to cause them to fall off on the front pulley.
In response to Husqvarna not answering me, take your fictitious & insulting answer and stuff it:
"If you sent me an email with stuff like this in an email I would not respond either. I would not even know where to start. You are so angry about stuff that you have not educated yourself on I could not imagine that anyone would want to correct you in fear they would get a worse name for them selves because you did not understand them...... It makes them smart to not take you on as I don't think you would care if they explained it the way I have."
Explained it the way you did? What, your erroneous and shoddy 'explanations'. Give me a break.
"I will not offer any type of proof in my statements because a simple google search will give you all the proof you need and probably don't want."
I just PROVED what a Google search will find, which is to DISPROVE your statements, Self-proclaimed expert who never was.
NO MORE COMMUNICATIONS FROM YOU. Go insult and degrade someone else. I'm sure if I searched your posts on this site, I'd find I'm not your first victim.
