Groundsmaster 4000-D Overheating Problems
I have a Toro Groundsmaster 4000D with approx 1000 hours (bought second user). After approx 10-20 minutes of work, the motor starts to lose power and stall. The temperature guage climbs rapidly and the coolant starts to boil.
I have blown all debris free from the radiators and checked that the fan belt is correctly tensioned. I have flushed out the cooling system and replaced the coolant.
