Our toro Rake and Vac model # 51574 has been used three times. this fall when we turned it on, it ran for about a half hour and then stopped....never to start again! Please help.

Remove the vacuum part and install the protection grid over the intake propeller. This protects you from getting caught in the propeller and engages the safety switch witch allows you to use it as a blower.

If you're Toro electric blower is slowing down, throwing sparks, overheating or not starting you may need to replace the carbon brushes. Replacing brushes and cleaning commutator early can prevent damage to motor armature!

The Mamco motor is WAY too much money.I bought brushes on E Bay and made them fit. #51591 takes 1/4 " square brushes.

sounds like the motor is worn out. Toro does not sell the motor separate. It is considered a throw away unit.
You will have to purchase a new one.
Sorry.
Good Day.

You should have another door that goes in front of the impeller (blade) which doesn't have a vacuum attachment. You should first detach the vacuum door from the bottom, put on the blower tube, and install the other door that came with the blower. Hope that helps.

I was able to find PDFs of manuals from the manufacturer directly at this site: https://homeownersolutions.toro.com
Just run a search based on your model. In this case, simply type in 51573 in their search box. You get access to an online interactive manual and also makes PDF available.
