Oh yeah, this started with snow. Snow is similar to dirt in that you're limited by the shear strength of the snow. You can also greatly improve the shear strength of snow by packing it. If I had to plow snow (and I don't) I'd go wide to get the surface area and add a bunch of weight. Back when we got enough snow to mess with in central Indiana, we ran 23-10.50 turf tires with chains and 40 lb wheel weights (per wheel) with pretty good luck. That combination worked much better than the 23-8.50 Carlisle ags with old style CC weights on my 126 used to pull my daughter on a sled. They tended to float on top of the snow until the going got tough. Then they'd dig a hole that they couldn't climb out of. So for me.. "Joe ol man" pushing snow with my Cubs, do I want a narrower or wider foot print? I just want to maximize my tractors power. Kohler engines, V-twins and beer. I think I love Wisconsin. Drag racers and pullers do need a bigger contact patch, but for different reasons. Same reason drag cars use the biggest tire, bigger contact patch. Randy Littrell Harrisonville,Mo. Hey Guys. I have a question. I understand that all things being equal a narrow tire puts more psi to the ground. So why do pullers use the widest tires they can fit on their machine? Is it because of the sled's transfer of weight? Thanks. Kohler engines, V-twins and beer. I think I love Wisconsin. Jerry M., Bruce, Bruce N., The K series engines have their ignition lobe running off the camshaft, and are ground so that they only fire every other revolution. Never mind. I was looking at an old profile from an old post. I found his new profile. Has anyone heard from, or know how to get in touch with James Diederichs? His profile no longer exists. He used to post a lot on this topic. I was working on a K321, so it was firing only on compression. Jerry M, I have a Fluke automotive multimeter--model 80 I think but not sure and I'm not home to check. I bought it because it had the tach capability and the thermocouple probe. The inductive pickup was a separate purchase for about $75. I've never been able to get a reliable reading on a one lung Kohler with it either. I don't remember the exact range of readings because it's been several months since I tried, but it seemed to jump (rapidly) from too low to about double what I expected to see. The low readings could be weak spark, but I don't understand the highs. Kohlers do only fire at the top of compression stroke and not at the top of the exhaust stroke, right? I've been trying to use a Fluke Frequency Counter (1970s vintage) to try and measure engine speed as a function of the frequency i.e 30hz = 3600 RPM if you get a pulse every other revolution of the crank. I guess due to all of the weird harmonics and spikes, I haven't been able to make it work yet, using the points side of the coil to ground as my reference. Might try hauling my old Tektronix O-scope out and give it a whirl. check out this electric powered Cub conversion; +1 top reduction pinion is another possibility There were Cubs in Florida! Rick thanks Darren, "Never argue with an idiot,they'll drag you down to their level, then beat you with experience." thank you Dennis DARREN - A quick check of the parts look-up will show the 124 has what is referred to as a 19 tooth second gear and the 70 has a 16 tooth second gear. First and third were always the same ratio therefore the same speed. You didn't mention it in your post but ONLY second gear is where Your 124 should be faster. Tire size, etc will also vary speed, larger dia. tires equals greater speed. There's also a stock 17-tooth second gear set that was available, think it was in the gear drive red tractors and maybe the quiet-lines. It's just a bit fater than the 16T but not as fast as the 19T. Relative speeds are 3.2 mph for 16T; 3.9 mph for 19T, and I think 3.4 mph for 17T, all with stock 23 inch dia. tires and 3600 rpm. Good morning all. Ryan, I got all my ideas for floating over ground from a local sod farm. they had a 4000 ford with 20.8 rear rubber and huge front tires I never got close enough to get the size off of. It looked strange but he could drive across a sod field and leave no impression pulling 8 or 10 gangs of real mowers. |
