Do you know how to adjust the reverse pedal on a john derre lt 190 lawn tractor? The pedal does not go down far enough and therefore goes very slow in reverse. Thanks

Hi,
Picture of the linkage at transaxle. Loosen #25 and tighten or loosen #18 to change speeds forward or reverve. Note: you will sacrifice one in favor of the other, cannot have both.
Peace,
