i,m going to redo my 45 h. (1 how much will a m&w goveron help the performance?) (2 were can i buy one? and how much do they cost?) I use thetractor for snow removal in the winter and pulling in the summer.

thanks howard

I have a pair of Super H's - one with the stock governor the other with an M&W.

Compared to stock the M&W is more sensitive. Ie. it has less RPM droop and opens the throttle more quickly as load is applied. So under variable load conditions the M&W-equipped tractor feels a bit more "snappy".

However the M&W does not increase horsepower or otherwise improve performance unless the stock governor is badly worn.

The downside of the M&W is under carb icing conditions, it's snappy throttle action makes the engine more apt to suddenly stall when load is applied until the engine is FULLY warmed up.

I can't help on where to get an M&W...

Bob pretty much said everything to say about them. we have a thompson rocket gov. in a super h and yes it makes it snappy and all but it came with it. I would not go and buy one for what they get for them, 200-400. you can make the stock gov. pretty snappy buy changing to a stiffer spring and also grinding the weights down, cost about $5 and a hour. if your set on getting one ebay is most likly the best place.

If its raw horsepower you are after an M&W govenor will dissapoint you. Where they shine is in what the car guys call "driveability". I bought a few of them 10 years ago while they were still cheap and run them on my "keeper tractors". Had more than one guy see how they behave and buy one on e-pay the next week. Not sure if I"d give up the 275-plus dollars they sell for these days, but not selling mine for that price either. They never sell cheap, so there certainly are plenty people out there thinking they are worth it.

I have a reprinted "serviceman"s guide to H" and a "blue ribbon" for the H. One or both of those books mention the stock governor allowing 10 percent variation in rpm and an IH optional governor that allowed for 5% variation being available as extra equipment. The 5% may have been standard for a power unit version of the same engine. my % figures are off memory.
Likely the MW and other governors were about the same function as the tighter tolerance IH option, but 50 years ago they probably would have been cheaper than the genuine IH part kit. The aftermarket governors may have reduced the amount of mechanical slop in the linkage compared to a worn in IH unit as well.

$5 and an hour of your time is cheaper than $300 for the same result!

I wonder the reasons for a 10% tolerance production governor when the difference between it and better ones is so obvious to the majority of users. Not only for operator"s perception, but shouldn"t accuracy be important for running pto and belt pulley equipment? I remember a discussion between Hugh and others about diesel vs gas on a square baler and the governor speed accuracy affecting tie cycles and shear bolt breaking.

The gas start diesels had 11% for tractors and 5% for power units. One of the problems with those is that the governor will not produce full fuel (and power) at less than full RPM. The 5% models are even worse. I think the gas tractors are different in that respect but could be wrong.

On all these machines the pto speed is where the governor reaches full power under load at max throttle. Add the 11% governor offset and you get high idle.

Interesting about the shear bolts.
