Hey guys. Looking at maybe buying a Iseki/Bolens G174 with the iseki tiller and front fmc hydro Blade. Has the turf tires that look to be original and red decals which tells me it is a 1978 model. Looks clean and straight, no leaks. Can you iseki owners give me some feedback on quality, parts price. Do these have a diff lock or posi rear? Why would this model come from the factory with the turf tires, 4x4 and front plow. Was it intended for general landscaping. Does the front blade have down pressure. Thanks for all your help.
