Cranking an M

Have a local M cheap, not running, and no winch on trailer. I figure borrowing the magneto off my H and a strap on gas tank will get me 2 of the 3 magic items needed to get it to run. Assuming no stuck valves, cracked head, etc, I'm confident I can get it going in a couple of hours.

My question: How much harder than an H is an M to crank? Just had heart surgery, and still limited to about 10 lbs of lift. H will crank easy peasy w/ a slow pull thru from 7:00 to 12:00 with no strain at all. (freaked my new bride out tho. 8) )
 
The r e are around a hundred cubes difference in the
2 I would let her try it first so you don't rip a
stitch.
 
Just depends on how wore out it is. If they have good compression they are a lot harder to crank than an H. Way to much if you just had surgery.
 
Please don't do it. I can hand crank one of my 400s but it is very hard and slow to roll over. The M would be a little easier, but not enough to allow you to do it without a high risk of hurting yourself.
Some things are not worth doing.

The M also stands up higher, the higher lift puts
you at a disadvantage unless you are taller than
average.

Do yourself a favor and get help with this project.
Even a big comealong with a teenage boy to pull the
handle will get it loaded eventually.
 
If the M has a mag installed note where the rotor is pointing before removing the mag same thing on the H. Before pulling the mag I would rub the points with a piece of320 wet or dry until shiny.
Then take the H and try to pull start the M. Hal
 
I would get out the jumper cables and try the starter long before I'd even consider trying to crank that tractor, especially considering recent heart surgery.

With 12V from your truck directly to the battery cables, it should be enough power to crank.

Make sure you pay the guy before you try to get it running. Otherwise the price is liable to go up.
 
I would grab a spare battery or two and use the starter to drive it
onto the trailer in 1st gear. If you back the trailer right up to it it
should be doable.

naw, don't do it.
An M with the plugs out probably takes more than 10lbs to get it turning depending on where the pistons are stopped.
Every time I don't listen to the doctors 'take it easy'......I have to get re-repaired!
carrying the crank handle over to the tractor is about your limit right now......
(ps, stand on a scale the next time you pull up on the crank on that easy H..bet you are way over)
 
Don't try starting it and find someone with a trailer with a winch on it and let them bring it home. You can then work on it when doctor releases from your limitation.

Oh, y'all have already convinced me - and this may be the reason I can't do it on a regular basis later. Watching my wife when she tried to crank the H, it looks like if the top of your shoulder is below the top of the arc of the crank makes it very awkward.

I have been VERY careful so far - my other hobby is shooting muzzle-loaders, and I have some very big ones. 16- and 12-bore rifles, and an 8-bore trap gun. I'm having to wait a full year to shoot them again, but I want to be in shape to do so when that year is up.

I will either try jumping it or pulling it w/ my F-250. Or maybe trailer my little 420W down there and make 2 trips to get everything home.
 
Your job for now, is to stand on the sidelines, HANDS in POCKETS, and provide adult supervision.
Occasional finger pointing and or wagging is allowed. BUT arms must be kept below shoulder height.
Also, mild cursing is allowed, but no yelling.
With the scrap industry booming, somebody right down the road has a roll-off truck and desire to make $100
 
If it were me, with the limitations, Id take a set
of jumper cables, disconnect the genny, hook the
jumper cables to the tow vehicle and battery cables
on the tractor, being careful of course, and turn it
over it that way. If not cables, just ground one
cable, and touch it to the starter post. If the
starter doesnt work, hire it done, or let it sit
until you can hand crank it. aint no tractor, no
matter how cheap, worth the price of a casket!
 

Yep. Can't climb up on or steer my JD 420W yet. H is doable - like climbing stairs, but 420 is like doing chin-ups.

They said 10 lb, but when I got home from hospital, a water-glass was too much and pulled the incision. I have gotten into the habit of gently testing ANYTHING I am about to do - and just not doing it if there is any doubt at all. Frustrating, but it is what it is.

Half-way through - 45 days- the 10 lb limit. Then it moves up to 50 lb or so. I was very blessed - I didn't have to get ripped from stem to stern, just minimal invasive to get a valve job on aorta. Full open-heart would have been 2x the restrictions.
 
Don't do it. I hand crank my H all the time. It is easy. My M, I never hand crank. Anyone that has tried to has cheated and used 2 hands because it is that much harder. I always leave the key off if someone just wants to see how hard it turns over. To tell ya the truth, I don't do it because its not only hard to do, I'm a little scared of being in a bad position for a kick back if it did. I crank in a safe manner for kick back possibility's but that would be hard for even me to do on the old M.
 
Forget about trying to start it with the starter or
hand cranking. Both too much work and if its
been sitting long, it probably wont go that easy
anyway. If you need to get it running, pull start it
with your pickup with a long chain. Put the tractor
in 5th gear.
 
10 pound limit!??

Forget cranking the tractor, you'd be pushing that
limit just turning a wrench!

To put it in perspective - just 30 foot pounds of
torque on a bolt is 15 pounds of force at the end
of a 24" breaker bar.

I think I'd wait a week or two on that one.
 
Your heart surgery cost you and your insurance company $25,000 or more? I wouldn't risk having to redo your surgery plus an even longer and more painful second recovery time just to save a $100 delivery charge. Once you do get that tractor home you still won't be able to do any serious work on it until next year anyway.

Do yourself a big favor, find another hobby for this summer. Forget about fixing up any tractors until next year, after you are fully healed.
