You can also get a ROPS (roll-over protection structure) and PTO shield to add to a gray market tractor. I had to quickly swith the transmission out of gear to prevent the spinning blades from driving the tractor forward. I occasionally use mine with a 4ft bush hog and have had some near misses when I tried to stop while approaching a fence. I would recommend adding a PTO overrun device if plan to use a rotary cutter. Other than these small differences these tractors are the same as the models made by Yanmar for the US. US made implements are made for a standard PTO RPM which is equal to the 1300d 1st PTO gear, and running implements in the higher gears could cause them to vibrate to pieces.
This works fine with the tiller, but could cause problems in the top 2 gears if used with a rotary cutter (bush-hog). The YM 1300d and some other gray market models also have a multi speed PTO. The YM 1300d is used in Japan primarily with the PTO tiller seen in the picture above. For this reason grey market tractors do not have a PTO overrun clutch which is designed to prevent energy from the heavy spinning blades from transfering back to the transmission of the tractor. In japan these tractors are mainly used in rice production where there is no need for heavy rotary implements (such as a bush-hog).
One for use in Japan and one for use in the US. Yanmar manufactures 2 types of many models of tractor. This means that this model was manufactured for use in Japan, and later legally imported to the United States. I mentioned in an earlier article that this model is a "gray market" tractor.
