This past summer spraying fence rows (5-7mph) out of the 1000-5 was so unbearable with heat in the cab. I have installed the fan and shield over the seat. I could perform the same job in my brothers 700 and no extra heat was noted. Really torqued me that I spent a lot more cash and was always wanting to take my brothers machine. The only difference I can see in the heat department (minus two different motors/machines) was the 700 had a deflector behind the radiator. I tore the hood off the 1000-5 and fabricated my own shield out of a heavy rubber conveyor belt. Not sure if this is going to be the fix but I bet 4 hours of my time today that it will.
