Questions & Answers

The question is. When I've been cutting grass for 30mins or so. It acts like it does not what to turn over,And will not start up. What do I need to fix on it.
Alvin for model number 13A2775S000 asked on 2018-09-19
Hello Alvin, thank you for your question. There are a few parts you might want to check/replace that can cause this issue. Condensation inside the gas tank is one culprit, but moisture can also enter the system through a loose or ill fitting gas cap. The best solution is to drain the mower?s gas tank and refill it with fresh gas. A clogged fuel filter (part number BS-298090S) can also cause a mower engine to die. Dirt and debris caught in the bottom of the gas tank can plug the fuel line where it exits the tank. You may want to change the fuel filter -- which is also a good practice if you have moisture issues. Damaged or worn spark plugs typically make starting a mower difficult, or make it run rough. Some spark plug problems can show up after the mower runs for a while. Remove the plug and inspect it for signs of wear or damage. This might include a cracked or chipped porcelain housing, or a rounded tip on the center electrode -- the small metal part that comes out of the porcelain on the firing end of the spark plug. Damaged plugs cannot be repaired, so you would have to replace it (part number 951-10292). If the firing end is full of carbon, you can clean it with a wire brush. Check the gap between the center electrode and the grounding electrode. If the gap is off you will have starting issues as well. You will also want to check your air filter, part number 937-05065A. Either too much or too little air can present problems. A dirty air filter affects the air that gets in the engine. Check and either clean or replace a dirty filter. You may also want to check the carburetor and either clean or replace it. A carburetor establishes the correct mix of fuel and air required for the unit to work properly. The carburetor part number is 951-12771A. I hope this information is helpful!
Soleniod bad. Replaced soleniod with new and connected wires, turned key and get from new soleniod a drumming sound. Did not take pictures before removing wires. Battery is fully charged. Could the starter be bad? Soleniod was clicking before replaced. HELP.

Solenoid was starting to fail causing difficulty in starting.
You have to remove the battery from under the seat and loosen 2 nuts. 4 wires must also be removed. The issue with this repair is the poor design by manufacturer in hiding this solenoid. All of the loosening and fastening must be done by touch. I also had to loosen a portion of the frame as the part would not come out or go in due to wire harness issues and clearance issues.

Lawntractor did not start
Removed battery and everything covering solenoid. Took wiring off solenoid and removed solenoid. Installed new one placing wires back like original. Put battery in, hooked it up, tested if new one worked. Worked great. Unhooked battery and reassembled what was removed. Had a few breaks while working on it, took longer than expected

Starter solinoid out
Due to Troy Bilt design, the starter solenoid is located in a very difficult place to access. Under the seat below the battery compartment and to the side. No easy access. Must take body cowling loose to reach. Must access through the battery compartment hole. Many screws are hidden when removing body cowling. Terrible design, It took less than 5 minutes to replace solenoid, but about 3 hours to gain access and re-assemble. This one would have been easier to take to shop than try to repair at home. Very poor design by Troy Bilt, Solinoid should have been mounted next to starter or under the hood.

Time Spent Repairing:
1-2 hours
Tools Used:
Screwdriver, Pliers, Socket set, Wrench Set, None
Starter Solenoid went out on a 2007 Bolens Model F765 w. 38" deck
1. Removed battery to get at the solenoid which is stuffed in under the left rear fender. Time: About 2 minutes.

2. Removed the two screws holding the solenoid bracket and wrestled the solenoid out from under the fender. This and getting it back in was the hardest part of the repair, because there is literally no room to work. Removed wires (4) from old solenoid.
Reassembled wires to new part. Time: 17 minutes

3. Spent 1.25 hours trying to get mounting bracket back over the fender. (bracket goes outside, solenoid inside.)

4. Reinstalled battery, hit the key and away she went.

Starter would not completely disengage from ring gear due to bad solinoid, starter was damaged due to interference.
Troy-Built Mustang 50" ZTR MOWER / TRACTOR
1. Disconnected & Removed battery to make room to get to solenoid. ...about 10 mins
2 Removed engine cover & starter ..about 20 mins
3 Disconnected & Removed solenoid, this is difficult due to location that is under the seat mount 1+ hour, lots of metric socket adapters and extensions needed. You must do it by "feel" since everything is a blind removal. Very bad design for solenoid location.
4 reassembled with new parts and tightened all down, 45 mins
I suggest you take pics of all solenoid connections before disconnecting.
