How many HP on the PTO?

Hi guys,

I was wondering how many HP an SuperMajor (an '61 with 52HP) has on the PTO? I think about 42HP.

The reason I ask, is because I have heard someone say, that the PTO is basically the PTO-gearbox/-axle of the E27N and therefor should not be (often) used for jobs that ask more than 27HP.
What do you think?

I have installed raised PTO on my Super.

Looking forward to your reactions.

Think your friend needs to see the 1300hp Merlin fitted in a basic Major rear end that was on the pulling circuit in Holland some years ago.

The gearbox and final drives were grossly over-engineered in the Major. When the 5000 came out it was actually lighter by 5cwt than the Major. Over here we have Majors with 6 cylinder engines in that were used on forage harvesters and Howard RotoSpreaders for many years without problems.

Gearbox and final drive problems on Majors came from people using the transmission hand brake to stop the tractor and breakup of the bull pinions and gear wheels due to letting one wheel spin then standing on the dif lock pedal. The Power Major/Super Major final drive was slightly weaker than the Major as Ford changed the specification but even so it will take a lot of power.

My books do not specify PTO Hhp but I would think that you are about right.

Pascal,

A E27N on TVO is approx 30 hp. A E27N is approx 36 HP (when new) and a E27N with Perkins P6 is 48 HP.

The last part of the tractor I would worry about is the PTO. That's realy tough.

Best regards.

Hi Pascal,
The grey wheeled Super Major produced 47HP at the PTO at 1700RPM, and were rated at 53.7BHP (also at 1700RPM).
