kto434 108 #1 Posted June 23, 2019 Newbie question: I have a 1968 Charger with a Sundstrand hydrostatic transmission. The tranny is smooth and quiet—no apparent problems. However, I noticed the cast iron gets hot to the touch after about an hour’s mowing use. Is that typical or may I have a problem? Thanks! Share this post Link to post Share on other sites
lynnmor 7,354 #2 Posted June 23, 2019 They get rather warm. Be sure that the cooling fins and the fan are clean. Run the engine full throttle when mowing. Share this post Link to post Share on other sites
pfrederi 17,879 #3 Posted June 23, 2019 Sundstrand hydros will run 180 when working hard...That is hot to the touch. Like lynnmore said keep here clean and run her at full throttle I blow mine off with compressed air if they are on mowing duty. Share this post Link to post Share on other sites
kto434 108 #4 Posted June 23, 2019 OK, thanks—got it. I do keep the cooling fins and really the whole tractor very clean and used my leaf blower after each use to blow off debris/dust. I will keep doing that too. Thanks again and take care! 1 Share this post Link to post Share on other sites
