7mph 4th gears for farmall m

zanslastclu · Jan 30, 2014

i have given up trying to find a 7mph gear attachment for a farmall m. has anyone out there tried to use the gears out of a i6 that has the faster 4th gear. i have a set of those gears. to me the standard 4th gear in the m is just too slow. i have several h farmalls with the 7mph attachment, they make wonderful hay raking tractors. thanks for any info on this subject.

Put over sized tires on 'er. Makes all the difference in the world.

put the i6 ring and pinion in the m. that will give you a faster gear.

If the field is fairly smooth, use 5th gear! Do not go too fast or your windrow will be too wide.

I-6 4th and 5th slider won't work for 5th speed on a M input shaft. M locks onto 20 teeth and the I-6 locks onto 23 teeth. If you use the I-6 transmission input shaft it uses a different constant mesh gear than a M. That speeds all gears up along with the PTO speed. Sixes use a ring and pinion that gives faster ground speeds in a M. But if you need a standard low gear ground speed you won't have it.
Try a 9 speed transmission. They speed the PTO also in high range. But for raking hay if you happen to use a PTO rake, placing tractor in a gear that will go 7MPH or faster and running less RPM will work for the PTO and use less fuel. For a ground driven rake no problem.

what... who in the heck rakes hay in 5th gear! that is a road gear and even at its slowest the tractor would be laboring. 4 th gear is even too fast as when raking alfalfa you will have no leaves left. I rake in 4th but only go 1/2 throttle.

Put in a M+W 9 speed. I have a M and a MD with this tranny. Makes a great raking tractor. I rake in 3rd gear High range and pull two john deere 660 rakes at about 1/4 throttle. Last 9 speed I bought cost $500.00 Takes a day to install.

Get all the gears out of Super M and then you will have your fast 4th gear. It will change 2nd and 3rd too.

Ditto on the 9 speed making a very useable tractor. I have Heisler 9 speeds in both a Farmall H and M which make them very helpful with a number of tasks. As mentioned in another response it also speeds up the PTO and belly pump so you have to be careful there if either are engaged. I have disconnects for the belly pump on my tractors when in high range. The M&W or Heisler neither one affect the original and standard 5th gear. They add four more gears between the original 4th and 5th gears. You end up with a 4th gear in high that is about 12 mph with a lot of pulling power for heavy loads. They are fairly common and for sale frequently so they are out there. I saw some fast 4th gears at times for sale in the classifieds in Red Power Magazine in the past. Justin Weber would be a person to contact as well. Good luck with your projects, Hal.

C'mon guys, it's not like you can just walk into the "Tractor Walmart" and they'll have a 9-speed sitting there on the shelf, on a styrofoam tray, wrapped in plastic...

Same deal with tires... Yeah, let's put $1800 in tires on a $1200 tractor just to go a little faster. Used tires you say? Refer back to my "Tractor Walmart" comment.

The most cost-effective and realistic approach is changing gears. You can get the gears from a Super M pretty cheap and pretty readily. If you do the work yourself you keep the costs down.

Maybe in your part of the country good SM gears are easy and cheep to come by. Easier for me to find a 9 speed as finding a 7 MPH M gear set, I-6 or w-6 around here or a SM gear set with shaft for less cost than a 9 speed.
If you know of a source for good SM 4th and 5th slider gears I would appreciate knowing where.
SM 4th speed is still a little slower than the 7MPH ones for a M.

I have never seen a 9-speed in my life, either on a tractor, or for sale around here.

Unfortunately the only Super M gear sets I know of off the top of my head are in working tractors.

My "reality check" is perhaps the "M" is not suitable for the job and needs replaced with another tractor if gears can't be put in cheaply or easily.
