Anyone work on ztr mowers?

I've got one that the motor is near shot on. I can replace the motor for about $1k but would like to know what it would cost to rebuild the current one. It's a toro 50" with a kohler courage 21hp.

Thanks.

That engine shouldn't be a grand.
Especially if you swap it yourself.

FWIW use an oil additive which contains zinc in your small engines. No catalytic converters to worry about. Much better protection. Mandatory to use it in flat tappet gas engines especially during break in.

I agree with you. Buts it's what I've been able to come with on the interweb.

I would search around for a used 21hp motor on craigslist. The bolt pattern and shaft size should be close but you will have to double check the with the make and model number.

Shot how? Smoking, knocking? I personally wouldn't put much into a kohler engine or buy a new one. If you must buy a new one, that one runs 850-1000 depending on where you get it.
I am going to guess that if it came originally with a 21 go kohler it is a sub $3000 mower, maybe a toro? (Could have it pegged wrong) if so, it is not worth spending that much on and you are better off buying a new mower.
If it is a 21hp single cylinder like I am thinking, it is not a great engine to start off with.
If you love the mower and must keep it, I would reccommend replacing the engine with a Kawasaki, Honda or Subaru/robin engine. Longer lasting, quieter and just a better engine.

It's smoking burning oil and knocking some. Low power. At the end of last cutting season it was running ok. Not like it used to. I ran it out of oil, when I realized what was going on I shut it down. Got it running again but now you can tell it's not what it used to be. Steering is slowly going out, I assume that's a filter that needs to be cleaned or changed. It's an 07 that's cut a lot of grass. Body and deck are still in pretty good condition.

Thanks for all the replys.

Should be able to rebuild for 1\2 or less if no damage was done. Check on a rebuild kit and go from there. Not much to those engines.
