multi power

How does the multi power work and what is it's function on a 150 MF? Thanks

A power shifted over/under. Just like the IH TA. It funcions differently but produces the same effect.

You can shift it without clutching. When in Lo it will free wheel, so make sure you are in Hi when going down a hill to get engine braking.

Acts as a 'splitter', to give two versions of the same gear, a 'hi' and a 'lo'. As others have said, there is no engine braking in 'Lo' - if you have any hills, be VERY careful driving a multi-power tractor and don't turn downhill in 'Lo' - or an exciting ride coming up! Jim. (had a MF 550 MP for many years - wouldn't let anyone jump on it but myself)

The low side is a mechanical jaw clutch, and the high side is a hydraulic clutch pack that "overdrives" the lo side when high is engaged. Engine braking only works in high, but with the jaw clutch design with the high engaged it also has a "hill hold" feature, meaning it won't roll backward either when high in high. Handy when used correctly. The MP shift needs to be in low for transmission shifting though.

It's function in any tractor that has it is to make a great tractor even better. The whole "free wheeling" thing is overblown IMO. It's a very handy thing to have.

Its a big deal to me with my AC tractors that hold back in low range its very handy especially when going down hills one of the big assets of high/low in the same mechanical gear.
On my Olivers I have to shift back into high range to go down a hill sorts defeats the purpose of the whole thing.If you don't have steep hills I guess it wouldn't matter.Plus with
the ones that fee wheel it has to be in the free wheeling low range to be able to shift gears with the AC high/low doesn't matter what range its in.

Have chopped thousands of tons of corn and haylage with an 1130 back in the day with tandem axle
forage wagons on these steep central NY hills without issues.

Bret 4207 You clearly haven't slid down a grassy hill with no engine braking leaving two slidey brown streaks behind you on the ground (and another somewhere else!!) trying to regain control and to stop a trailer jack-knifing, or you would not not be making that comment! MF Multi power is a potentially lethal system on farms with hills. Been there, done it! Jim

I get a long fine with my Olvers but it'd be a lot better if they held back in low range and also if they had the neutral in between high and low like the AC tractors.

Yeah Jim, actually I have with an 800 Ford, a VAC Case, a David Brown 990 and a Cockshutt 30- none of which have Multipower. I've also slid down a hill with a MF 65 is 1st gear high range. I've even slid down a hill on a crawler tractor. I've slid with the engine braking and with the rear brakes locked right up. "Potentially lethal" is over blowing the whole issue by many magnitudes, right up there with "tricycle tractors tip over easily" and " Ford tractor flip over backwards easily". A little common sense goes a log ways, but sometimes it doens't matter what you're driving, ice/mud/too much weight on a trailer/wagon and you WILL slide.

True, I had an 850 JD with tricycle front end and used to bush hog some pretty steep hills. Never had a problem but with my New Holland
Boomer 35 I have to remember to keep the loader down low. Common sense does go a long way.
