I have an MTD 42a707 18.5 hp riding lawnmower. The engine turns over plenty fast, it is getting gas, and has new spark plugs, but is not getting a spark. Does that model have a coil?

If you're not starting and the plug is firing good, it's likely the "anti-backfire valve" has taken a dump. It screws into the bottom of the carb and has a couple of wires on a plug attached. Remove and replace.
The drive pulley on my MTD riding lawn mower broke. I removed the bolt that holds it on. Do I have to have a "puller" to remove the pulley or just will power and a hammer?
R.Wilson from Emmett, ID
I wouldn't think twice. Slap a puller on it.
If you are going to be fixing things like this you really should have a set of three-jaw pullers.
A pulley "puller" is a good idea. Harbor-Freight in Spokane on Sprague and Sullivan has them.
Look for a product called, "Fluid Film" at hardware or farm store. It's based on lanolin/wool wax, and is the best stuff I've ever found for getting really difficult parts to release.
i have a 1994 mtd 18 horse lawn tractor. it has a 6 speed control, it's stuck in the third speed and can't start the engine.
My 14 hp. MTD riding lawn mower will only start with a charger attached at 75 amp jump start setting even with a new fully charged battery. How do I know if it is the solenoid or the starter? I do hear a single click noise each time I turn the key. The starter is warm after trying a few times which lends me to believe it is the starter. Thanks for any suggestions.
If its clicking its probably the starter solenoid
is it like this?

Thank you attosa. That is exactly how it is acting. I will test it to be sure but I think that is it.
My right back tire is flat, I took off the screw, but can't pull off the tire. Is it supposed to come off from the front of the wheel? In other words are the things that look like washers just frozen because of rust? Or does it pull off from the back of the tire?
By Linda W. from Salt Lake City, UT
I have a John Deere but I believe removing the rear tire from your machine would be the same. The wheel is held on with a snap ring. You will need a special pair of pliers to remove the snap ring. You should be able to buy the pliers at an auto store. The ring looks like a washer except it has a piece cut out and two holes drilled into the washer near the opening. The pliers have two prongs that fit into the holes. Squeezing the pliers expand the ring so you can remove it. You could also visit a riding mower repair shop and they will help you. They should be listed in the phone book.
Don't think that has a snap ring if not lots of pb blaster and I hooks an good size puller
I'm having trouble putting the front tire back on a riding lawn mower which has a snap ring type thing on it but it dose not have any holes for the snap ring pliers. It looks like it should snap on if you push it but there is not room to push it and I didnt take it off so I dont know how it came off just trying to use the mower, i tried using a washer on the outside just to push it on but didnt work.
I have a 18hp MTD mower that won't turn over. I've replace the starter switch, starter solenoid, and safety switch, as well as replaced the 7.5 amp fuse. Any ideas?

I usually try spraying a little carb cleaner in as I turn the key. You can try the fuel filter and make sure your gas is still good after sitting all winter.
I was having the same problem. It turns out that a piece of cord was wrapped so tightly around the blade shaft that it was frozen there.
Have you checked your spark plug for carbon, that would be my next check, then the fuel filter to see if it's clogged.
My MTD RH115B ride-on mower developed a problem last year where the drive belts for the blade and wheels repeatedly came off.
I had it serviced twice last summer by a local plant-hire company, the second time specifically to address this issue. However last weekend I used it for the first time this year and the drive belt for the wheels came off three times in half an hour. The last time the belt for the rear wheels - under the seat - went under the belt wheel and I cannot get it back on without removing the belt wheel. It has what looks like a nut on the top, but turing it just turns the wheel. How do I get the wheel off to replace the belt and why would the belts keep coming off?
Here is the website from the company for troubleshooting: http://www.mtdp mower-drive-belt
It seems involved. You have to take off a lot of parts. They recommend putting them in the order you took them off in order to get them back on correctly.
Thanks for that. Looks like I'd got as far as step 5 before I gave up. When I try to loosen the nut ( as described ) the 'pulley' just turns with the nut. Don't know how to fix the pulley in order to turn the nut. There is a small hole in it that I've seen be used on other machinery to stop a part turning but it's not obvious how in this case.
The engine starts with no problem, but begins to surge, RPMs up and down. Why?
You might need to clean its carbs
it drives ok in reverse but not forward
My MTD ride on mower will start and drive with no problem, but as soon as I lower the blade to cut the grass the fuse blows causing the mower to cut out. Has anyone any idea why this is happening?
You're belts under the lawn mower are to tight or to loose or the spindle is lose they must be bolt drive tight.
Sound like to me I have a pinch wire under the mower when I lower it it make a ground who's pinchingna wire causing the wire to ground out an there for blowing the fuse, but I could be wrong.
My MTD 660 (about 10 years old) stalls when making a left turn. I've looked for rubbed wires, been over the steering column and linkages, and checked the safeties. I weigh almost 300 lbs, so the seat switch isn't the problem. I've never run into something like this! Recommendations?
I had that problem once with a car. It was the carburetor.
I needed to replace the ignition switch on my Bolens riding mower. I never had a picture of which wires went to which tabs on the back of the ignition so now I don't know which wire goes where. Please help. It is a 13WC762065 Bolens lawn tractor by MTD.
If you google Bolens Ingition Switch diagrams you will find plenty of images. However, I think it would be best to watch the film on YouTube of how to change your ignition switch. You can see the film here:
How do I change the PTO cable on my MTD riding mower, and how do I get the cover thing completely off from under the seat? I took out the four screws that I could see and the one under the foot rest area. But, it still won't come off. Of course I disconnected the battery and took it out.
I found out that there are two screws under the big sticker in the middle of the floorboard thing that is in between the seat and the steering wheel. I took them out and was able to change the PTO cable. It's still a b#tch to get the spring off and back on from under the left side of the seat.
I have a 42" 7 speed MTD Gold riding mower with a 19 hp Kohler engine. I can not get it to start. I have checked the fuel filter, replaced the battery and the spark plug and cleaned the carberator. When I hit it with some starter fluid, it cranks but just falls dead, then won't start again. The last time is did start was last summer. My son tried to jump it, but inverted the positive and the negative cables. Any ideas?

My MTD model Briggs & Stratton engine 42A707 (700) won't start but keeps spinning. It stops running and will not run again. I replaced the fuel filter, drained off the fuel, and replaced the Magnetron unit. I have also replaced the spark plugs and cleaned the air filter. The choke opened and closed nicely, suddenly it cranked and started for 5 seconds and went dead. It still cranks but just won't start. The battery is new. I noticed that I can crank the engine when I have the gear in forward or reverse without pressing the clutch. Any idea what happen here? Please help, thanks!

I recommend that you have the mower serviced by a qualified mech. It sounds like you have an electrical issue in the safety switches.
I am looking for a wiring harness for a 1997 MTD Power Pro lawnmower, model number - 13al452f120.
By gary from Gadsden, AL
I went to mtdproducts.com put in your part number 13AL452F120 and the return answer was no such part number. Why not call MTD at 1-800-269-6215.
My Lawn Boy MTD 13AO672G120 suddenly shifted into the fastest gear. It made for an exciting ride back through the woods on trails, but I can't get it out of that gear. It starts fine, but even in reverse, goes shooting out of the garage in the fastest gear. Any ideas on a fix? The brakes don't slow it down. The brake spring was gone, but I replaced it with no results.
I have a Yard Machine riding lawnmower (Model # 13A176F729). I just purchased it used. I believe I'm having an intermittent problem with the PTO belt. I get the "vacuum noise" when the mower is cutting. About 30 seconds later, that noise disappears, and the mower stops cutting. The mower still moves, but it won't cut. Then, I get the noise and it cuts. A few seconds later, the noise goes away, and the mower won't cut.
Do I need to replace a belt or two?
How do you check the electric clutch on a MTD riding mower? Mine seems to have a lot of free play. Is this normal?
By Kevin P.
I've got an older MTD Yard Machine 17 and a half horsepower, 46 inch cut. I need to know how to put the belt on the deck. It has three blades and I cannot figure out how to intertwined the belt through all the pulleys. I need a diagram.

Where is the gizmo on my 16.5 MTD riding mower (15 yrs old about) that will let me push it out of gear. It is stuck in a field and won't start up so. I need to push it. Thank you very much.
My garden tractor blows the fuse only when I turn it off.
By Kent W
I have replaced the belts, but the tractor still will not move. Could it be the transmission?
By Tim B.
How do I adjust the belts so that my gears are all useable? I have a MTD.
By Elli from Nanango
My MTD riding mower keeps throwing the rear drive belt. It is a 14hp, 38 inch cut. It is fine on level ground, but seems to throw the belt on a decline or when turning on an uneven area. I replaced both drive belts in April and started having this problem in early June.

How do I install a deck engagement cable on my MTD mower?
I have a Yard Machine MTD Special Edition, 18 HP Briggs and Stratton. I have installed a new battery, solenoid, and new battery cables. I checked all of the safety switches. When I try to start the engine with the key I get a chatter from the solenoid. I have started the engine by using a battery with jumping cables. What could be wrong?
