Participanthi bradley,
pretty sure thats common practice on running gear, spreaders, binders and such. the hammerstrap(?) is a fairly important peice. takes some strain off the ash. the weak link then, would be how the pole attaches to the wagon gear. if that is good and sound, no worries.
i just got through splicing a new end on a mower pole that i snapped the yoke end off. i think the rest of the pole is pretty sound, but wouldn’t lend that tool out to someone else. we are all betting our life on that 3″ peice of hardwood, ain’t we?
one by one, i have replaced alot of poles with iron square tubing. 2-2.5″, a little heavy, but doesn’t rot as quick. mitchParticipanteveryone would probably agree that it takes extra time with horses harnessing, brushing and so on. but when you like being around the animals, it isn’t really extra time, is it?
Participanti don’t think that there will ever be an end to small farms. people just want to farm. and they always find a way to do it.
the same people never attend ag- school. they just figure it out the old way. policy makers don’t have as much power and control as they think. my money is on the dark horse.Participantcarl,
wondering how your leg healed up? nasty wound there.Participantgive me some numbers and i can try and mill one out for you.
Participanthey billy,
meaders want $45- 50 for a new pole. seems pricey to me. i have a friend who works up treelength firewood and he throws out a few ash for me now and then. six or seven inch saws out a fairly nice tapered pole. much cheaper if you do eight or ten at a time.
i know my number 9 is fussy about getting a snug fit up under the castings, don’t know about your number four, but you might measure it first to make your pole big enough to fit. the number nine wants 5″ across at the butt end.
mitchParticipantjen, i’ve been living under the assumption (correct or not) that a skunk has to arch his back and lay his tail uo over his back to open his musk glands and get a good shot at you. and in a (havaheart?) trap, he is challenged to operate. i just walked up to the trap with the tarp in front of me and followed your procedure. i was told you could pick them up by the tail and they couldn’t spray you, but………..never had the nerve to try that one out. mitch
Participanthi jay, when i came up with the twelve turns per second it sounded impossible. then i came up with it two ways and it sounded a little better. my math could be wrong as well. so any that want, double check the numbers. the horse mower is the best example. no matter what the ground speed, its the same two inches per cut. simple math. gotta love it. my team cuts about an acre per hour. but if you run the numbers, staying in grass all the time, and never resting, its only possible to cut 1.81 acres at 2.5 mph. so horses are fairly efficient allowing for the weather and bugs. i’ve always liked the sound of a horse mower. thanks jay, mitch

I figured out the correct RPM for the crankwheel based on the dimensions of a #7 I had in the shop for restoration.
5,280 feet/mile x 12 inches in a foot = 63360 inches divided by 104″ (the circumference of a 32-inch steel wheel) = 609 wheel rotations per mile.
If I count the crankwheel turning 26 times for every drive wheel rotation, it turns 15834 times in a mile. Divide that by 60 minutes in an hour, and you get 294 RPMs at a speed of 1 MPH.
So, if an average team goes 2.5 MPH while mowing, the crankwheel’s optimum speed should be 659 RPMs.
If my small engine runs at 2200 RPM, a reasonable speed to reduce noise and stench, and the pulley reduces output 7:1, then my cranckwheel turns at 315 RPM, which should be fine, because the ponies shorter legs mean their gait is half the speed of a “real” horse.
I’m a newspaper reporter by trade, so my math is probably wrong. Anybody see mistakes in my figures?Hey Daniel, I was checking out your math, and went out to the back of the barn and found our old Dearborn mower for the 8n. it powered a 8” pulley that drove a 5.5” pulley on the pitman flywheel driving the knife. Based on those numbers, it sped up the 540 pto to about 720 rpm’s or about 12 knife cycles per second. Holy smoke that can’t be right, can it? Sounds too fast. So I tried the number 7 mower. 2.5 miles per hour is 158400 inches per 3600 seconds. Divide the distance(158400 “) by 104” wheel circumference, and the drive wheel turns over 1523 times. Multiply that(1523) by the 26 knife cycles per wheel rev. and you get 39,600 knife cycles per hour . divide that by the 3600 seconds in the hour and its turning 11 times per second on the horse mower. Same crazy number (almost) so it must be so. More math says the horse mower at 2.5 mph is moving 44” per second, and cutting 11 knife cycles per second,four inches of forward motion per knife cycle, or two inches of forward motion per one close of the knife, and that starts to sound believable to me. Your math checks out, best of luck with your mower. mitch
Participantterrible news geoff. can not imagine your grief. we are happy no one was hurt, and congratulations on your beautiful grandchild. you have to count your blessings when you can.
best wishes, mitchParticipantabout that gasket…………i took an oil bath last summer trying to get by without and couldn’t squeeze that cover down hard enough..so i desperation i plunked the cover down on a tractor inner tube and cut a not so pretty one out and i worked pretty well. it seems to have made it through the winter, and you could easily make a prettier one than my try. i tried to make mine a half inch bigger inside and out from the cover, with holes for the bolts that were cut first. but a nice clean factory cork would sure look sweet. good luck there, mitch
Participantthanks for those fine photos donn. great seeing your shop and farm. everytime i count the numbers come up short, so i gave up counting. don’t know if that is a good idea, but there you go. thanks again, mitch
Participantandy,
you could try a diamond pattern. where your wider spacing was followed by another gang. i only say it because that seemed to be the common shape of most of the handmade cultivators i ran into. also is the deeper penetration bringing up the sod you plowed down? on new ground and a fairly good job of plowing, i try and leave the sod down. a spike tooth is a good idea and might be the ticket.mitch
ParticipantDon’t have a lot of knowledge about this scoot, except like most, saw the film with its step by step directions to making one, and made one. Choked in the end and put a loose pole rigging in front. So I can’t say I have had a lot of experience with them. But for the most part, it’s a ben thresher three beam sled, and behaves a lot like a woods scoot. Lots of flex and good float. In my whole life here in maine, I have only run into a couple similar sleds, old and run out, and to a one, were called by the owners, sap sleds. Makes me wonder, with vermonts sugar industry, if that particular sled is a combination woods sap sled. Its how we use ours. Low and flat with a deck added is perfect for collecting sap. Then again, I can’t say. You could always bolt a pole on to the stub pole and get a little use out of the sled and put in a proper pole when you had a moment. Pretty sled though. First time I saw one in that film, I had to have one.
Participantnice work daniel. how many rpms on the pitman?
