Gravely Pro 36 Deck Belt

Hi, my gravely pro 36 walk behind constantly has the blades engaged. What could cause this? They are on as soon as it is started then when I actually push the lever to engage them it really doesnt do much but bogg down the engine. Do you think it just needs a new belt or what? Thanks for any help

I would look at the belt and ALL belt guides, A belt guide bent out of whack can cause the deck to drive continuously or a rolled belt can cause engine bog when fully engaged.

I did loosen up the guides and the belt is pretty loose, but still is engaging the blades. I got this mower for a real good price and so far the only things wrong with it is the belt issue, the engine not seeming to have enough rpms, and a drive belt falls off regularly. Any suggestions are welcomed. Thanks

That's not the way to go about it, Engage the deck with engine off. Adjust any guides about 1/8" away from the back side of the belt or away from the pulley if the guide is near a pulley, Use the same method on the drive belt as well and see what happens.

To go any deeper than the above I'll need the model and serial number off the power unit not the deck.

Could have the wrong belt from an auto parts store... Very common when dealing with smaller machines.
