Question: Does this fit both the 4.5 quart and 5 quart mixers?
Document: It only cost about $5. I used the push piece provided by the meat grinder attachment to shove things down.I did tomatoes earlier this year using this item and I thought it was super slow. (It was the first time I used the attachments (both of them.)) I just didn't have the mixer on #4. I had it on #3. That speed makes a huge difference. I did tomatoes, again, and it was wonderful!
Had this for a little over 2 months and it's been more than helpful!! Cut down processing time of tomatoes to almost nothing. Just clean, core, give a squeeze to get out the extra juice and maybe chunk so they'll fit into the chute. Done!! Processed over 5 bushels of tomatoes. I've used it for apples, too. I just sliced those and sent them through, seeds and all. Wonderful applesauce. Clean up is pretty easy.
I'm sure it's a good product but it did not fit on my older model Kitchen Aid and by the time i realized that (summer, canning time) it was too late to return.
Having recently purchased theKitchenAid KP26M1PSL Professional 600 Series 6-Quart Stand Mixer, Silverfor my fiance for Christmas, I ended up getting this attachment as one of her birthday presents in January because as good as a KitchenAid mixer is by itself you can only really mix/beat with it.
This strainer works well, but be sure to read the directions, and don't put berries in it. Also, the conical sieve is difficult to clean, and should come with a brush that can fit inside it to remove soft food that can become wedged in seam.
Rather than spending 300$ on an Italian pasta sauce stainer, I bought this attachment. 36L of pasta sauce was done in a matter of 1.5h. That's over 2.5 bushels of tomatoes!Worth every penny!
I found this attachment when looking for an alternative to my labor-intensive hand-crank food mill for processing tomatoes to freeze. To my delight, about 10 minutes after attaching this to my mixer I had 4+ quarts of skinless, seedless tomato puree, all without a sore arm.
(Ok, the apples were already softened. )I just could not bring myself to buy the attachment for the top (bigger holder costing $20). So, I used a 2 quart funnel that I previously bought from Amazon. I just cut off about 1 1/2 inches of the bottom of the funnel and put that into the feed. (It's the Hopkins 8F multi-purpose funnel:  2 quart capacity.
I cut them in half, threw them into a pot and heated them up, cooked them for about 15 minutes, then ran them through the strainer. I made seasoned tomatoes, marinara sauce and just plain tomato sauce (I had a *lot* of tomatoes).If you are on the fence about this item, my recommendation is to buy it and buy the $5 funnel. It will save you a boatload of time and effort.
With this attachment, I simply cut the tomatoes in cubes and fed them through and out came a beautiful tomato sauce. All the dry, undesirable bits were seperated out with no need to put them through a second pass. I would have given this a 5-star, but there is one thing that I found this attachment struggles to handle. It does not process berries with a lot of seeds very well, such as blackberries.
Answer: It fits in where the attachments would go so as far as i know,  its universal in the mixers sizes, however you do need the meat grinder attachment to make this attachment work.
