The IMT IMT539 Tractor was manufactured between 1980 and 1990. Make sure you have access to your tractor serial number, because there is a chance that the IMT IMT539 parts you need depend on that serial number. The 3-point hitch is very reliable, capable to lift 2425.5 lbs [1100 kg]. It is also worth noting that the PTO runs at 540 rpms.
