Yup it's an 18-36 I or the last version made with flat spoke wheels, rather than the round ones of the earlier models. It is unrestored, and most who see it tell me NOT TO TOUCH IT with anything other than boiled linseed oil to preserve it. As of yet I just keep it clean and shedded. The lights were my grandfathers addition, donated from a 1926 Essex car.....This tractor has been a running example but for a few years in the early 70's when an uncle overhauled the Maddison Kipp oiler and the Bosch magneto. It has been inside for the most part as well. The engine was over hauled in 1949 with factory parts that were auctioned off in Charles City Ia. to free up wherehouse space for the new post war equiptment. After that it was used to run a feed mill, untill some time in the late 50's. We are blessed to still have it in the family.
The Avery steamer is a rare bird we have been told. Twin cylinder, and very smooth operation on the belt. Not so goood to pull with however as it is very heavy. The 75HP Case in one of the picks is the plow "traction engine". After we overhauled it and broke in the babitt bearings, it will carry the front wheels withthe 8 bottom plow behind it. The Case as a wide rear wheel with extensions, aslo rare we have been told. The show is at Jefferson Iowa in late July. Usually about 40 tractors of all makes show up, and every year the show just gets a little bigger/better. Always conflicts with other things to do on the last weekend in July though. They have a morning Tractor drive of about 35 miles that is really popular....

18-36 perhaps? Along with the 88 to the left; that 15-30 [or maybe 10-20] is among some mean company! Gotta love the underslung Avery too!
