Just purchased a older Yard Machine Lawn Tractor which has no ID sticker. I need to ID the model number or series number as I need the PTO linkages. The link from the PTO handle is broken and the link from the bottom lever to the pulley is missing. Also, the brake spring is loose and I can't figure out where to attach it. It is a 20 hp, I/C, 14 speed with a 46" cutting deck. The Briggs & Stratton motor model number is 461707, Type 0143E1, Code No 9807215A. Attached are some pictures.. The second picture is looking in from the left side of the deck (opposite from grass discharge). The hanging spring is from the lever going to the brake. I can't figure out where it attaches. The lever in front of it with the pin and the empty hole is the PTO lever which should actuate the pulley to the left. Anyone know part numbers or can send me a picture of what it is suppose to look like? This is my first post. Hope I did it correctly.
