20 Most Recent Toro Z Master Zero Turn Riding Lawn Mower 19 Hp 34" Cut Questions & Answers

Is it a drive belt or on the deck? I helped a friend of mine replace the drive belt tension spring on his. It was located just above the drive pully. Was a very stout spring. Used a brake spring tool and it popped right on. Is this the same thing you are talking about? the L shaped piece with a belt tensioner on it? If not, I will get back on here later and try to help. Thanks.

which model kawasaki engine?

try tightenig the oil filter a little that will stop small filter leaks

Hione thing to try sstart up ngine le it warm up and get a screw diver and turn the mix screw on the carb 1/4 turn out and try that engage PTO if nothing turn another 1/4 if nothing turn engine of and turn mixure sew all the way in very easy dont force it just when it stops turn 1 and 1/4 turn to 1and 1/2 out now start it and try pto if its still slowing down turn another 1/4 turn out now if that didnt work just make sure you have a clean air filter and fuel filter and spark plug before you do any of the above then u will need carb rebuilt please use fresh gas otherwise you will very low powerJoeJoe

Here is a table with the small Kawasaki engines listed. I hope this helps.

Does it have a B&S motor? If it does, look on the back side of the cover (above the spark plug) or the opposite side of the carb. and you should see " Model, Type, and Code" and some numbers underneath them. Look under "Code", the first two digits is the year of the motor. For example, "01" means it was made in 2001. Thats if its the original motor that was made for that machine, thats the year of your machine. If its not an B&S, call your local Toro dealer and they can tell you.

Question edited for clarity. When you put it away at the end of last snow season, I expect you just rolled it to the corner of the garage and left it until now? The two stroke gas in the carburetor, went bad and gummy. It starts on starter fluid because no gas is coming from the carb. https://www.google.com/search?q=toro+ccr+2450+carburetor+cleaning ..

See if the videos help. https://www.google.com/search?q=Briggs+and+Stratton+engine+model+252416+0757+01.install+the+spring+260695+for+the+governor+lever ..

did you make sure it has spark. i have learned over the years because an electronic is new doesn't mean its good? If it has spark remove the plug and put a bit of gas in the hole and re install plug see if it will fire on that gas. if it does its the carb something is probably blocking fuel. check the compression if its low compression it will not run. if u dont have a compression checker just remove the plug stick your finger tight over the plug hole and pull it over it should blow your finger off the hole.

Yes, decompression lowers cylinder pressure during low rpm while cranking. If you're concerned with compression, you need to do a leakdown test. Inexpensive (~$30) units are available through numerous eVendors. The leakdown test provides a metered volume of air that is translated and displayed on a pressure gauge simply labeled high (excessive leakage), moderate, or low (nominal leakage).

It's an L-head engine and once they get a few hundred hours run time, the valves wear into the hard seat, lash goes to zero, and they become hard to start. You can check valve lash by removing the crankcase breather (two screws). If lash is near zero, time for a valve job. Plenty of how to videos on the web. If it's easy start, just low power then less likely a valve lash issue.

There are many things that cause low power. Bad fuel, water in fuel (fuel bowl), fouled carburetor, poor spark, fouled plug, improper plug gap, wrong plug, weak ignition module.

If you have no forward, no reverse but the motor is still running normally the most likely reason for this is the main drive belt. This connects the motor to the transmission. If it stretches, breaks or drops off the drive pulleys you will lose all movement.

My thought is the seat safety switch is faulty, because normally these mowers won't work unless someone is sitting in the seat when if goes into the blade drive. There are other ideas in the videos. Frayed wires in the harness somewhere?
