The Sixty was produced from 1925 to 1931 and achieved great success in every field of endeavor it entered, such as agriculture, mining, logging, and construction.
Early tractor companies focused on producing tractors and left the development of attachments such as winches and dozer blades to other companies that created a vibrant aftermarket. Companies such as Willamette-Hyster, LeTourneau, LaPlant-Choate, Austin Western, and Baker produced a multitude of useful implements that multiplied the productive capability of the crawler tractor.
This Sixty has an example of an early hydraulic powered dozer blade, which was less common than cable operated blades due to hydraulic manufacturing being in it's infancy. A single large hydraulic ram mounted behind the driver elevates the blade and provides a small amount of downforce to the blade, but not nearly as much as would be developed in later decades.
What you get: When you order a tractor Shapeways prints it and mails it directly to you. The tractor arrives unpainted and you finish it off however you would like. You can read the material descriptions here on Shapeways to get a better feel for the plastic and paint options, but we will share our experiences with cleaning and painting here so you know what to expect. There are also many threads on the internet with people sharing painting and cleaning tips. Be aware, until you paint the tractor it is hard to see the details, they don't show well on the clear plastic. Painting brings it alive, so don't fret when you first pull the tractor out of the box.
Shapeways prints the tractors with a wax support base material. After printing they melt the wax in an oven and then clean the tractor with hot oil and then hot water. The tractor you receive will usually need some further cleaning before you paint it. You can usually clean it by hand by gently immersing and 'swishing' it in hot water and dish soap, but you may not get all the residue off. A hand cleaning is usually good enough for painting, but if you want the best prep for your painting you may want to do a little more. We use an ultrasonic cleaner with hot water and vinegar and find we get very good results.
After you have cleaned the tractor to your satisfaction you select your method of painting. It is possible to hand paint with a brush and get good results, but we prefer using an airbrush. We apply a sub-coat of black paint to the entire tractor and then after it dries we apply a coat of gray paint. The black sub-coat makes the details "pop" through the gray paint, without it the details aren't as pronounced. We use acrylic paints because we find the results are as pleasing as enamel paint without the fumes and health concerns, but either type of paint works fine.
If you'd prefer not to do all the cleaning and painting we also sell fully cleaned and painted tractors that we list on Ebay under the name "Tracmodel" and also direct if you message us here or on Facebook at our Facebook page "Tracmodel".
