I HAVE A 2010 TROY BILT LAWN TRACTOR. WE HAVE TO CHANGE THE BLADE AND TRANS BELT. ONCE WE CHANGED IT, WE PUT IT IN GEAR AND GO ABOUT 10 FT. THEN IT STOPS AND WON'T MOVE. IT IS A 17.5, 42 IN. CUT,

Lack of Lubrication. Without adequate lubrication, the gears in the transmission can become reluctant and hard to shift. Check the transmission fluid level regularly and change the fluid based on the schedule recommended in the owner's manual provided by Troy-Bilt.

Zoom into the diagram, remove (item 45) belt cover to expose the belt and pulleys. Take note of how the belt is routed.! you will need to follow the same route with the new belt. You may need to remove the Blade guard (item 40) if the belt doesn't fit over the head of the guard. There may also be a sprung idle tension pulley, which will take up the slack in the belt once replaced. Looks pretty straight forward.

How to Change the Blade on Your Troy Bilt Rider

http://www.bing.com/videos/search?q=M15542+murray+blade+change&FORM=HDRSC3

There is a spring attached to a tensioner that probably came unhooked while changing the belt. Higher deck settings push the deck backwards enough to spin the blades, the lower setting need the spring tensioner to take up the slack in the belt.

One or more of your drive belts is in need of adjustment or replacement, maybe. Possibly, your electric (or manual) PTO clutch could also be adjusted. You do have the spring tensioner on the deck engaged, right? You say the engine doesn't bog when this happens so I am inclined to think "clutch" and/or "PTO belt" to the deck and/or the "deck tensioner" are the things to check.

The tensioner will be the easiest, it is a handle on the left side ON the deck. Has a BIG spring on it. Make sure it is engaged.

Is yours a Troy Bilt manufactured in Troy New York or is it another manufacturer (MTD?). Troy Bilt is actually out of business, having sold the Troy name to a variety of makers depending on the model line. I don't have the run down on who makes what any more (tillers, chippers, mowers, blowers, trimmers, etc.), but Troy Bilt of Troy, NY is no more. :-(

I have a 16 HP Troy with 42 inch deck driven through a electric clutch. I also have a "grass pump" on my deck. Important maintenance tips: Keep the bearings greased, keep the deck clean underneath. The belt on the deck should have the tensioner released when you are NOT mowing. Keep the blades sharp and in good repair. Mow with engine at full speed. When you get to areas of heavy growth, slow the tractor down (hydro drive) or reduce to a lower gear (gear drive). NEVER adjust speed using the "clutch" (hydro drive or gear drive). When you engage the blades (electric or manual) always have the engine just above idle, bring the engine speed up slowly to preserve the belts and reduce stress on all components.

I am sure this is the fix for your trouble. If there is anything else or if I missed the ball, please let me know and we will go further.

Thanks for your question @ FixYa.com

HOW TO CHANGE A BELT ON

Troy-Bilt 17.5-HP Manual 42" Riding Mower

You need to adjust the gas pedal. Info should be in the owners manual. I have it in my Troy Bilt Bronco manual. It say to adjust it in my book after replacing the trans drive belt. Maybe that will help.

You turn the mower over, remove the blade with a 9/16 or 5/8 socket. There is a bolt holding shroud on, 3/8 or 7/16, there are two screws by the rear wheels, 7/16 that need to be removed. Once the shroud is removed, belt can be removed and new one put on.

you need to screw the transmision adjustment in so that it is push all the way in to gear.
