Hi Marco, I have been watching this thread with a fair amount of interest, as I have an older Yanmar 187-D that I inherited from my parent's farm. It has only 200 hours on it, but was plagued by constant issues with the safety interconnects (mostly because it was never garaged, I believe). The power plant is a 3 cylinder diesel, so we had planned on using a conventional 8" advanced DC motor, or equivalent (thinking salvage from an old forklift- possibly along with the industrial controller) Had planned to run it at 48-72 volts using group 31 batteries (I have about a dozen left over from a previous project), then swapping to lithiums when some older ones come through that need to be re-purposed. Another thought that occurred to us was to use an alltrax controller (inexpensive & robust) if the industrial unit was not viable. The tractor has been sitting as a future project that was initially set aside when the economy took a dive, and stayed put as my Dad's health declined (the plan was to do it as another one of our father-son projects). The adc puts out about 20hp, but do not be confused by the rating, as the torque is roughly equivalent to that of a small block V-8 (I have put a few in car conversions that have performed well against nicely built street machines!). Over the past few months, I have been concentrating on cleaning out or completing several of my unfinished projects, and have caught myself looking wistfully at the tractor project that sits alongside my old carport. My son has asked when we are going to do something with it, so I am thinking that the spring is looking to be good for this idea. I want to thank you for bringing the topic to this forum.
