When I bought my machine it also had very jerky controls when the motor was above idle. I followed all the good advice on here for resolving the problem and did find some loose screws on the steering plate but couldn't get the controls to smooth out. As preparation for a deeper investigation I decided to remove the panels on the bottom of the machine for a thorough cleaning. As I removed the inspection panel under the center of the machine the large bolt that secures the front of the hydrostatic pump to the chassis fell out on the ground. I felt like I'd just hit the lottery. Reinstalling and tightening the bolt fixed 90% of the jerkiness in the controls. This may not be the source of your problem but it's worth the 5 minutes required to check that this bolt is tight. And thank you to all the members on here who have helped accelerate my learning curve on these machines. John</p></blockquote><p></p>
