Default 1572,1772 Temperature differance
Any ideas why my 1772 runs about 20 degrees cooler (130) than my 1572 (150). I checked the thermostats both are in and working. I used a laser thermometer and checked all around engine, Thermostat housing and radiator and all are about 20 degrees cooler. I also put a thermometer in radiater with same results.

Nice set of supers! What's the model of your other super? Sorry, I can't help on the temp question.

I'd say calcium and rust buildup inside the cooling system. May even be a difference in the radiator build. If the tractors are only running at 130 and 150 it's nothing to worry about anyway. AFAIC, that's a little cool. I like to see water temps of 175-200 (working temp). Too cool a cylinder will wear funny.

The temperature of the engine should be what the thermostats are rated at. They should not open allowing coolant to circulate through the radiator until they reach that temperature, just allowing coolant circulate through out the engine until they reach that point. Sounds like both are opening a little soon. If you are using the dash gage as a reference they too could not be reading properly. The engine will run better, cleaner, and have more power when up to recommended temperature.

Maybe the radiator in the 1772 is in a little better shape than the 1572. My 1572 ran a little on the hot side. I installed a new thermostat and there was no change in temp. I used a radiator flush and refilled. I also added a little Water Wetter to the radiator and that brought the temp guage down considerably.

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.

MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
