This season I bought a used Lesco 48" Hydro walk behind (my first hydro) 2002 model w/ 400 hrs. It is very hard to use. Its a fight to go straight. Hands are very sore from constantly using levers, springs seem tight. Any help, suggestions, ideas, and thoughts are certainly welcome. Anybody else experience this issue? Lesco owners ever got springs with less tension. Ready to go back to my belt drive.
