I own a really nice Ford 4000 3 Cyl gas, runs great now with a new carb.. The serial numbers are. C1491226J7, 6E17G and 41024C.. the serial doesn't make any sense. All I;ve found starting with a C is Ford 3000's. Is that possible? It has High and Low range and 4 speeds in each range. I'm looking at buying a tank trailer with a capacity of 3250 gallons on a tandem axel chasis. I need to spread water on my arena for dust control. Does anyone think the 4000 3 cyl gas can handle pulling say 2500 to 3000 gallons? I have no idea what the towing capacity is of the tractor.. Thanks in advance...
