Hello -
I have a Troy Bilt Model Series 77T Lawn tractor - and the unit starts up fine, but when I go to engage the blades there's no power to them. However, when I put the tractor in reverse and go to engage the blades - I lose power like normal.

All of the belts seem to be in place and I can raise and lower the deck belt fine.
Is it a spark plug or something with the battery?

Any help would be appreciated.

Thanks,

Hi,
What on earth is "losing power like normal." If it has an electric PTO and the clutch does not engage, check for fuses in the circuit, broken wires, bad ground, defective PTO switch and/or ignition switch.
Peace,
