1450 vibrations

I contacted my buddy who builds pullers and he gave me three companies, none of which are i the Nashville area. Vogel Manufacturing in Effingham, IL; Lakota Racing in Carrollton, OH; and Tooter's Mower Parts & Repair, Owensboro, KY. You can Google these for contact info and I understand they have Facebook pages, but since I don't do social media I can't verify that. Hope this helps.

Thanks again Kenny. I will check them out.

Sorry 2 post the same.

I will just let her shake and forget about it.

Is there any particular RPM range this occurs in? Mid range, rated speed, idle??

 

[wh cc guy]

Idle, mid range.

 

[Greg Riutzel]

Yep, mid range is the worst. There's no way around it. When my engine is at idle, it's fairly smooth, a tad lumpy but nothing to rattle the tractor. Going to mid range everything rattles including my a$$. At 3,600 rated RPM it all smooths out nicely. When I got the tractor the iso mounts were shot and the only way to keep it from shaking all over was to keep it at top RPM. Swapping out the gears for the balance plate helped as the engine balance/feel is a bit better than stock. The new iso mounts took care of everything else as long as I stayed in idle range or top RPM.

You can get the rotating assembly balanced maybe even better than OEM. You will still be stuck with unbalanced lateral forces at 90* and 270* from TDC as the crank rotates through those planes On top of that there's dynamic unbalance from different piston speeds at TDC and BDC. It is the nature of all piston driven engines and there's no economical way I know to get around it other than multi cylinders that can cancel each other's forces depending on the crank plane to make a smoother running engine. Other than that, just stay out of mid range

Checked out the balancing company and the cost is around 200 to 300 dollars to balance the crank. If you add gaskets and other thing needed along with tires, belts, filters, oils and other odds and ends I will have more invested than the tractor is worth.
Think I will take Greg's advise.
