More about the International Harvester HYDRO 186

In 1976, the very first International Harvester HYDRO 186 Tractors went out. They were produced until 1981. The International Harvester HYDRO 186 Tractor first came out at a price of $33,900 (1981), but you might be one of the lucky ones who found a good deal lower than that. The bad news is that, like any other tractor, the International Harvester HYDRO 186 Tractor needs spare parts to keep it running; the good news is that we have all the parts you need at 60% off dealer prices in our inventory. Make sure you have access to your tractor serial number, because there is a chance that the International Harvester HYDRO 186 parts you need depend on that serial number. Usually, the serial number is printed on the rear axle. That serial number is determined by the year of manufacturing, so for a 1976 model, it starts with 8601, for a 1977 model it starts with 8813, for a 1978 model it starts with 9806, for a 1979 model it starts with 10626, for a 1980 model it starts with 11465, for a 1981 model it starts with 12279. Some International Harvester HYDRO 186 Tractors have a 4x2 2WD chassis, but there are also some with a 4x4 MFWD 4WD (optional) chassis, all equipped with power assist steering. They also have hydraulic disc brakes. The type 2 3-point hitch is very reliable. It is also worth noting that the independent rear PTO runs at 540/1000 rpms. The International Harvester HYDRO 186 has an open center hydraulics system with a 28.5 gal [107.9 L] capacity. The pump does the job pushing 12 gpm [45.4 lpm] fluids in the hydraulics system.
