Troy Bilt 175HP Manual 42" Riding Mower - Answered Questions & Fixed issues

If you didn't put fuel stabilizer in gas before letting the mower setup all winter, your gas has gunked up your carb. You can verify this by removing the air filter and spraying starter fluid in the carb. If it cranks with the starter fluid, the carb is dirty. Pull the carb and clean it out

Your owner's manual indicates to change the oil and replace the oil fitler on page 19 as part of the regular maintenance schedule. Whether or not your exact engine application does indeed have the filter is the engine manufacturer's option. Here is your manual.

This sounds like your Deck Belt drive has come off or has stretched & needs replacement. This is normal wear & tear, easy to look for under the machine, you may be able to slip it back, on see this site for full descriptions. http://www.troybiltpartsonline.com/oemparts.

Belts dont move mower back and forth, there is a bar that engage the hidrolic transfer, perhaps you move it and you have not tracking power, or, there are a series of rods that actuate the hidrolic, coud be that any of those rods came undone, if any of these to scenarios is happening to you, consider have the hidrolics chec out.
Good luck to you. If you need further help, reach me via phone at https://www.6ya.com/expert/gerardo_79638d1eac6a0a1f

Those belts do not tighten you will have to replace it,sorry.

Check your battery and see if its fully charged. I had a battery that the charger said was fully charged but a cell was dead. Take it to a battery store and they will check it free of charge. If that's not the problem check all the battery cables on both ends for being tight and clean. If that's not the problem you could have a bad starter.

Didn't take long to find this belt. Check out this link: http://www.amazon.com/s/ref=nb_sb_noss?url=search-alias%3Daps&field-keywords=pto+belt+742-0485

Normally this caused by a leaky float needle valve in the carburetor; although, if you have a vacuum operated fuel pump it internal may ruptured.

Sounds like you have an issue with a broken or off pulley belt.

THE FUEL PUMP SHOULD BE ON THE SIDE OF THE MOTOR. THERE IS THREE HOSES THAT WILL HAVE TO BE UNHOOK TO PLACE THE NEW PUMP INTO PLACE BE SURE TO HOOK THE SAME WAY THAT YOU TAKE THE OD ONE OFF

there is a safety switch that may be out of adjustment when you engage the deck

Sounds like you have the belt running in the opposite direction. You need to Change the way the belt is routed around the pulleys

Battery connections clean? neg. and pos. clutch pushed in? safety switches disengaged? starter solenoid bad

I had a similar problem with my TroyBilt 50 inch zero turn mower. Was cutting grass when it stopped going either forward or backward even though it would start and the PTO would move the cutting blades. Turned out the tensioner spring for the belt that drives the motors near the rear wheels had gone missing. Searched the yard where I had cut and moved the machine but couldn't find it. A new one cost me about $7.50. Put the new one on and it worked fine.

Check under the seat under the battery box there you should find the drive pulleys for the rear end the belt could be worn out and turned inside out causing it to slip or stop pulling once it heats up mine was installed inside out from Lowes when I purchased the mower causing me to replace the belt hope this helps

When the brake is locked it will prevent you from pressing the motion pedal. The brake lock is located on the plastic panel beneath the steering wheel. If its stuck and wont release then use one hand to fiddle the brake pedal and use your other hand to pull the brake lock tab out. A little lubricant on the rod and lock will help in the future. Once the brake pedal is released, if the brake is still sticking, lube the pins in the brake caliper. Locate the caliper on the right side of the tranny just in front of the axle. You will see a round disk half covered by a block and a bracket with a spring and rod. Use a penetrant lube and soak the block covering the disk on the disk side.Then grab the bracket at the spring and push toward rear of mower to release the brake and work the brake a few times till the 2 pins in the caliper free up. With mower in neutral and the brake released you should be able to freely move the mower by hand. If the mower still wont drive after that then the brake is not your problem.

NORMALLY THERE IS A KNOB OR LEAVER FOR YOUR PARKING BRAKE AND IS CONNECTED TO THAT PEDAL BRAKE TO LOCK IT UP FOR PARKING, THROUGH A SERIES OF RODS CHECK THOSE RODS IF STILL ATTACH TOGETHER, PRETTY SURE THAT IS THE PROBLEM, GOOD LUCK If you need further help, reach me via phone at https://www.6ya.com/expert/gerardo_79638d1eac6a0a1f
