Strange part is the old coil + was wired to the points and condenser. Now I know that ain't right! Really strange part is this tractor ran good when I parked it a month or two ago other than a POS plastic fuel pump that I knew was junk. Figured sort out the fuel pump issues and she be good to go.

Too dark to mow, but I did drive them around a bit and so far like the results.

WHX?? 47,013 #12854 Posted September 22, 2021 This one Dan does have custody of now .... figured it be better to just let him have it rather than a nasty fight in divorce court. Actually a real nice 856 and prolly wouldn't take much to get her chugging. 'Side looks much better in his pasture than mine. I ain't one for naming tractors but this one is ole pale face.... Does fit and gives character. Ever wonder what a PO might have been thinkin when he picked up a rattle can?!?! 3 Share this post Link to post Share on other sites

You get some seat time on that C-121 & she'll stay right where she is. Ole pale face does look good sittin' in my pasture. I Haven't had a chance to look at her much yet but I think a couple of hours time will have her up & running. Edited September 22, 2021 by Achto 3 1 Share this post Link to post Share on other sites

Jhook 849 #12857 Posted September 22, 2021 Did some trading with a buddy of mine today. The non running but very nice shape 416h with 42 in RD deck is gone, but i now have this nice rj58. Pretty happy with it. 2 5 1 Share this post Link to post Share on other sites
Inspectorjoe 438 #12858 Posted September 22, 2021 Today was the day the C-120 I bought back in June was finally welcomed as an official member of the family. A little background info is in order. I love my wife dearly, but she doesn't see the need for multiple tractors (or indeed any tractor) on our 1/3 acre property. Early this year, I agreed to request that I don't buy any more tractors. I had my fingers crossed behind my back. I had been using a Trac-Vac for fall leaf cleanup, but after seeing a video of how well a lawn sweeper did the job, I decided to go that route, and started looking for something with a rear discharge deck to pull it. . I located a C-120 in central NJ. As I've done so many times in the past, I waited till my wife left for work at 2:30 pm, then went and picked up my new acquisition. Before she got home, I had it unloaded and stashed in a spot in the yard that she never goes to. After about two weeks, I brought it into the garage in place of a 1973 14 HP (I put the no-name in the yard where the C-120 had been). I had total confidence she wouldn't notice the difference. Eventually, I made room in a shed and stashed the C-120 there until last week. Although my wife acts like she doesn't like tractors, I know that she enjoys driving them, so if I have trailer work to do, I usually ask her to help out behind the wheel. Then a few days ago, the big moment came. I wanted to see how well the rear discharge mower cut, so I asked her to drive it. Success! She never commented on the drive control being in a different place than it is on the no name. So today I took the final step, and brought it into the garage and parked it next to the no name. Now, if she notices it and asks when I got it, I can truthfully say 'a long time ago'. The last picture shows who actually wears the pants in this marriage. 14 1 1 5 Share this post Link to post Share on other sites

The coil doesn't care what wires are hooked up where as long as the points and condenser are on the same terminal. Power from the battery is still going to flow through the primary circuit to the points and to ground. A magnetic field is still going to be generated. Most what would happen is the magnetic poles would be reversed. 1 Share this post Link to post Share on other sites

I've had a couple tractors come into our possession that were hooked up backwards as well... Share this post Link to post Share on other sites
squonk 39,113 #12861 Posted September 22, 2021 (edited) The primary circuit of the coil is just a pass thru. When the points are closed the power flows from what ever terminal the 12 volt source is connected to through the windings and back out to the points and ground. Magnetic field builds. When the points open the flow stops and the magnetic field collapses and the lines of magnetism cross the secondary windings and induces a high voltage current. The poles being north/south or south/north don't effect anything. Look at this picture. The coil primary is not grounded in the coil body. the primary circuit goes in and goes out. In this example the primary enters and goes down the coil to the bottom and then up and out. In Jim's scenario the primary current will travel down the coil then into the windings and then out changing the polarity of the magnetic field but not the primary or secondary circuits.

Interesting but having some experience with old positive ground 6v farm tractors they will run with the coil wires set up for negative ground but they will run better if you put the points and condenser on the + terminal. 1 Share this post Link to post Share on other sites
WHX?? 47,013 #12867 Posted September 22, 2021 I would have to agree with Squonky on the coil thing. Unless the coil is a newfangled one and has electronics of sorts buried in it. Even with a internal resistor buried in it still should not matter? I guess my ? would be then why are the primary posts labeled then? Industry standard? I threw a coil on it marked external resistor as it was the only one I had laying around and it got her over to the shop. Lots of arcing on the points tho so new coil and condenser to follow.

squonk 39,113 #12868 Posted September 22, 2021 Yeah get that coil off of there or you will burn up the points. You need that internal resistor to cut the primary current back. Share this post Link to post Share on other sites

He ran it alot and I did too with no issues before I noticed it was marked external. Share this post Link to post Share on other sites
Oldskool 6,585 #12870 Posted September 22, 2021 I couldn't get my ducks in a row so I figured Horses might be easier. Almost all of them anyways.. Also had a pull off showdown with the GT14 and Hiram, moving around some old riding mowers to clean up for snow. Well I'm kinda surprises Hiram came out on top. 5 Share this post Link to post Share on other sites

WheelHorse520H 706 #12874 Posted September 23, 2021 (edited) Well, I took about 0.030” off of the cylinder head on the aftermarket “greyhound” engine on the 607 and forgot to adjust the rocker arms before I turned the engine by hand, and well let’s just say it didn’t end well. New rocker arms to be ordered soon. What happened was I tightened the rocker too much, then dropped a piece behind the flywheel (or so I thought, it wasn’t there I think it’s on the ground somewhere) so what I tried to take the flywheel off to find the piece, I turned it and it locked up, I thought it was the piece I dropped…nope. The top of the valve was against the piston because I didn’t adjust it yet and I turned my breaker bar, the SNAP. YES it broke loose. 1/2 a second later NNNOOOO!!! The poor little rocker arm didn’t stand a chance. Let this be a lesson to you all (probably more myself though), ADJUST YOUR VALVES AND ROCKERS AS SOON AS THEY ARE INSTALLED.
