First time for me here but I think my son (Danf) used be on the site quite a bit. I have an older Toro 62" hydro walk behind that I have re-engined once at about 1200 hrs(now has about 2000 hrs on it) started to mow with it this afternoon and the left drive motor seems to be running about half speed. Checked all the linkages and everything seems fine there. Anybody go any ideas? Thanks in advance!
