This was a good fit for re-powering my 48" Toro Proline Walk Behind which originally had a Kohler CV15.
This has been a good motor so far. I have had it installed now for about 2 weeks and have roughly 3hrs on it.
This did not come with a muffler so I had to buy part # 32-786-05-S (exhaust output on side of grass discharge).
I also had to purchase new mounting bolts (10mm) which were not included either.There were mounting holes already in the mower deck however I had to drill them bigger for the larger bolts. The original motor had a choke setup within the speed control lever. This motor has separate linkage for the choke. I went to a local dealer and purchased a choke cable and mounted it next to the speed control lever for this fix.
Also note the new motor did Not come with oil in it. You will need to fill with oil prior to use.
I hope and intend to get many years out of this motor.
