I've heard that the PP axle has a grease hole in the center of it. You'll need a grease gun with a 'point applicator' attachment. First take off the wheel and gear cover, taking note of any washers or other parts and how they go back. Clean the end of the axle to find the lube hole - shoot some grease in there which will force the dirty grease and crud out and lubricate the small parts. Do this on both sides one-at-a-time so you have a reference for how the wheel goes back on. You could clean up the wheel, axle and ring gear and put some grease on them before putting that side back together and you will have done a nice job on the rear end of the mower. Hopefully I'm not all wet on the grease hole, but it was on here just a few months ago.

Link: Upright-Castle-Princess? This is my spinning wheel. She is an upright or Castle style wheel with inbuilt lazy kate from Norway. Sold by Frank Herring and Sons in the UK. They would import these wheels on a very ad hoc basis from just one man named Tomasli in Norway; send him some money and six months later they would have a delivery of wheels. This was because he only made them in the winter when the fjords would close because of the snow, so he would spend his winters making spinning wheels. Unfortunately the gentleman passed in the 1980s and they were not carried since then obviously. And evidently he also sent shipments to the US where they dubbed the wheel the Norwegian Princess, whereas Frank Herring sold them as a Norwegian Upright. In 1970 when mine was bought, it was sold for £21 + £1 carriage (its written on the bottom of my wheel). In 1989 they were going for £199. They are made of pine, but he had a knack for choosing the timber and constructing the wheels in such a way that when/if the pine warped, the whole wheel did at the same time at the same rate so they will always run true. She is a superb little wheel with only two ratios in the whorl, double drive, and I have spun everything from lace to aran on her so she is really very versatile.

Your wheel as is, is not in operating condition although all the parts seem to be present. (Consult the link below.) From what I can find, a wheel like yours in working order would be in the range of $800. The spining head (on your machine) has to be truned 90 degrees, locked in place and belting installed. Yours is a double head; The belt would run over the wheel twice, first passing over one pulley on the spinner, over the wheel, and then over the second pulley. I can't see in your photo how the treadle is connected to the wheel. This can be done by one of two methods. One method uses a flat wood stick for a connecting rod between the crank arm and the treadle. The second method uses a stout string or leather thong to connect the crank to the treadle. The end of the string is wrapped and tied over a bearing sleeve on the crank; The other end is merely tied to the treadle. Here is a link that might be useful: Spinning wheel

Yes, I spin. I have an Ashford traditional, but there are many kinds out there. Get on ravelry.com. It's free, and there is a site for buying and selling wheels, spindles, carders, drum carders, etc. Also check crags list, and most importantly of all, if you have a shop close to you, go test drive as many wheels as you can. Check your local yarn shop and put up a notice asking about wheel, lessons and all things spinning related. Being in MN there should be LOTS of people who spin! It may take a little detective work, but you won't be sorry. I have been a spinner for more than 30 years. I spin to spin, I never have a project in mind when I start. I just love the feel of the fiber and how it runs through my fingers onto the bobbin. I try to spin a little every day, some days more than others LOL. Good luck in your search, I hope you find what you are looking for!! Welcome to the world of spinners. Oh, and we have a spin in public day as well (don't know when it is) just like the knit in public day.
