About us
Lisle Corporation recently celebrated the company's founding and 115 years of continuous manufacturing in Clarinda, Iowa in 2018. The privately owned company is led today by third, fourth, fifth and sixth generation family members.
C.A. Lisle started the company in 1903 with the first product being horse-powered water well drilling machines. To combat the seasonality of the well drilling business, the young company branched out and also manufactured washing machines, cream separators, and push-type reel lawn mowers.

- Reviewed in the United States on April 23, 2021I liked it. Just needs to be a tighter fit. A little sloppy fit, if I didn't drain the trans I don't think It would hold the fluid back. Not bad for the price.
