Used the weedcutter for about an hour cutting trails for the atv's through tall grass. Love using it with the front pto on the 7016. Unfortunately the overheating issue has gotten bad enough I have to run it with the hood off. It never has a problem now. I want to get an older hood (3300 or 3400 series?) and then put the heat shield on the top of the motor so the engine can blow the hot air out. As it is it blasts the back of the headlights, gets trapped under the hood and I think sucks it back in and a never ending cycle begins. Then it starts missing and is WAY down on power after 15 minutes even when temps are in the 70's. Oh well, works great this way!!

i think youre probably right on with the heat shield thing...
I have the same shield on mine directing the air downward thru the
front grill... and the front grill absolutely
allows a ton of air to escape... after mowing on a dry hot day it
gets a good amount of grass dust collected there on the inside...
I wouldnt have thought it would have been so much but it is... |

Nice to see you getting some seat time again Jon! Is that the field at the showgrounds by your Dad's place?
My 716-6 had the same issue with the Kohler, but only when it was above 70 degrees or so. My buddy that took it off my hands has a chunk of 2x4 that he props the hood a bit with when mwoing in the heat. Just a couple inches does the trick for him. |

And I personally love the look of the later 7000's with those headlights, but it never failed even with two different engines (originally the 16hp and now a 12hp repower) that after about 20 minutes of mowing they will lose power and start to stutter. With the hood off, never a problem. I think especially without the deflector sheet on the engine blowing air down and out the front grille, that hot air hits the back of the headlights, recirculates between the engine and hood, and even gets sucked back in to go through the cooling system again. Only a matter of time before overheating.... |

Moses, I don't think any of us have a definitive answer to the issue. The early 700/7000, 3300 &3400 series are in my opinion the prettiest tractors but it is hard to beat the old wide open hoods of the FDT's. |

Small engine mufflers can run between 500 and 700 degrees centigrade. You would think that routing something that hot out from under the hood, would help with temperatures? Especially if it is as confided and as restricted as its being stated. You guys would definitely know better, I'm still new to these machines and their specific quirks. |

Hey Jon, Nice job. You have reminded me my "project" for last week was setting up my weedcutter on my "new" 3212H which didn't get done.
I am using my 7016-6 strictly for roto-tilling and it barely works the tractor. So it doesn't have a heat issue. I have had for certain heat issues with my 7013S when mowing heavy grass in the summer heat.
Sorry to see you still having trouble with your 6 speed. I have a nice straight hood from a 3314H minus lights you can have for $10 plus S&H. email if interested.
Edit: I dont think you can solve the problem re routing the exhaust. There is a very strong airflow coming out of the front of the engine, especially around the exhaust valve. The 7000 series headlights do obstruct this flow and is bound to cause problems in hot weather when working the machine for longer periods of time... |

Underhood heat is the main reason I went to a 900/7100 series for lawn mowing duty. The 700 series I used last year and the year previous just got hot, even last year with the headlights out, and my exhaust ran outside too. The amount of additional air space under the hood of the 900 is huge!
I'd say looking funny while mowing is sure better than a cooked engine. Leave the hood in the garage. |

I have heard elsewhere that overheating was an issue on the late model 700 and 7000 series because the direct flow from under the hood was blocked by the headlights |

I don't quite think there's a flaw in the design of the hoods because my 7016 has never gotten hotter than any of my other tractors and it gets worked the hardest by far. As long as the fins are cleaned and all the shroud and tin work is clean it should stay cool. Another thing to look at or think about is you really shouldn't work these engines or any air-cooled engines hard at idle. |

You could also be looking for hoods off the early 7000 series as well as it has the lights mounted in pods on the side like the 3300 and 3400 series.
You might also try venting the hood similar to the 7100, 900 series. |

Just curious as to shy the weed cutter has a full loop slider on the right side, but only a teardrop shaped slider on it's left? I'm assuming it throws the cut stuff to the left & the tearrdrop shape lets it pass over it easier?
It was supposed to act like a plow,, the front is angled,, but not quite enough,,, they had good intensions when they designed it though. |

Daniel, I never really thought about it either but I think you are correct. With my experince the cutter doesn't really throw the cuttings very far, unless I hit a downed branch then watch out splinters are going everywhere! It more lays the stuff down and chops it up, so if there were a full loop in the left it would probably get bound up.
It truly is awesome though, I have cut fields of grass taller than the stacks are high. |

It all goes left, Daniel. I never thought of it but I bet thats why. |
