I recently changed from bar blades to swing backs on my MTD ride on mower(don't laugh,I they're not the greatest,but my wife bought it for me).I don't know if it's coincidence,but when I lower the blades (to get closer to the ground)the mower feels like it's struggling and I can hear the revs dropping.Is my mower in need of help?Grass isn't long,flattish ground,not wet.I never noticed this before with the old bar blades.
I've been pretty slack with maintenance and I've only had it serviced a couple of times in 8 years.
Any ideas?
