Proper way to shift Super C into 4th gear

JohnV2000 · Jul 2, 2019

When I try to shift into 4th gear on my Super C, the engine sputters a lot and sounds like it is going to stall, however, most of the time it eventually starts going. Once it is in 4th gear it runs great, goes up hills and seems powerful.

Is there a proper way to shift into 4th? Obviously I only try it on flat ground, never try shifting into 4th uphill.

Basically, I am wondering how quickly I should let off the clutch and where the throttle should be set at to get in 4th gear.

Thanks,

John

If it's like our Minnie mo it's a
really fast gear. Only way we can
get going is nice flat ground.
Then after a minute you can't
recall why you want to go that
fast!! But it bogs down a bit
getting started... No problems on
our Fords.....lol.

We had one growing up the only time i would go into 4th was when i was coming out of 3rd moving along.

Time flies, guess I haven't had mine in high gear in about ten years. Used to drive it about 12-14 miles to the local threshing show. High gear is no problem on the level or down hill, up hill and not very steep either I wind it up in 3rd, lower the throttle, double clutch it, ease it through neutral into high raise the throttle again slowly. Hard to do without grinding gears now and then.

On my M I wind it up in fourth, push in the clutch , pull the
throttle all the way down, and put it into fifth. A double clutch
does wonders. I usually have it hooked to the mixer grinder so
there?s also some weight pushing me and keeping
momentum.

I shift tractors just like notjustair, similar to a car, truck, motorcycle. But I realize many young folks nowadays are not
used to driving with a clutch.

If your carb has a load (high idle mixture) screw, open it 1/4 turn at a time to see if you can eliminate the stutter. Jim

If your carb is like the one on my C you
have only one mixture screw. Turn the
screw inward, CW, a quarter turn at a
time. That will add more fuel and make
more power under load.

Too much fuel will cause your plugs to
turn black real fast, carbon up.

As mentioned, best to get it moving in 3rd first, then go to 4th. Starting in 4th from a standing start is not usually a good idea. Takes a little practice to get into 4th without grinding the gears.

Just curious, why is it not a good idea to start from not rolling directly into 4th gear?

It's not quite as bad with just an empty tractor, but if you're pulling a load you'll end up revving the engine and slipping the clutch to get it moving. That is hard on the clutch.

If you can't double clutch just put a little pressure on the gears as they are grinding until they are the same speed & slide together.

something wrong if that tractor wont start out in 4th. also if in 3rd gear slow that throttle down to as slow as it will go at the same time you step on clutch shift into 4th and throttle up and go. no clutch riding either. as I always say, either step on the clutch completely or keep your foot off of it.using the rpm's to your advantage is a help. plus an untuned tractor is a buggar to shift on the fly. some guys double clutch also, and it does work . you need practice and timing.

If the engine is tuned up right including the carburetor the engine should not sputter at any time once it is warmed up. It might pull way down when you let the clutch out in fourth gear but it should not sputter or miss a beat.

It's hard on clutch. Don't know of any vehicle you can start off in 4th gear from a dead stop.

BarnyardEngineering · Jul 3, 2019

I've been starting tractors off from a dead stop in road gear for the better part of 40 years and have yet to lose a clutch in one.

Being able to float from 3rd to 4th, or double clutching, or getting the timing right are good skills to have, and something to pursue, but not absolutely necessary. Yes, you are not doing the clutch any good by slipping it for a few seconds, but it is not an instant death sentence.

If the engine is cold a little bit of choke can help with the spitting and sputtering. Once it's warmed up it should not do that if the tractor is tuned properly.
