rem722 28 #1 Posted 9 hours ago Hi Guys, has anyone ever thought of placing a torque converter on a round hood and then chain drive to input shaft with a sprocket? I need torque to pull deer up hill out of woods.....please be kind this is just a idea that I have... 1 Share this post Link to post Share on other sites
702854boy 430 #2 Posted 9 hours ago (edited) It might be easier to seek out a six speed transmission or an 8 speed transmission. The six speed is a direct bolt in except for the little hole you have to drill for the hi-lo lever, the 8 speed you have to do a little more modification for the brake linkage and still have to drill the hole. Another benefit of the 6 speed is that it has a limited slip differential, the 8 speed does not. We put a six speed in our 854 and I love it, @Handy Don and @ri702bill have experience or at least some pointers. Or, depending on the model of roundhood, I can speak from experience that the 7 and 8 horsepower Kohler engines already have a crap ton of torque and my 8 horse can move the D.O.T snowpiles at the end of the road and barely even grunt. The main thing you need is traction. If you don't have traction that's when you'll have trouble. *Edit, I reread the topic post and realize that this is for an 854.

If you don't have traction that's when you'll have trouble That is true regardless of the transmission. Having the extra 4:1 Low Range reduction is huge - just like in a car or truck, you are trading off ground speed in low range to gain much more torque. The regular 1st gear in a 3 or 4 speed is 102 to 1.... 1st gear in Low Range is 408 to 1!!! The closest chain drive scenario I can come up with is like an old Minibike. Centrifugal clutch and a chain drive to the rear sprocket. Some words of caution regarding chain drives - they are intended for lower feet per minute speeds than a V belt drive. They are also unforgiving in a jam - a V belt will slip, saving the mechanism... 1 Share this post Link to post Share on other sites
pfrederi 19,638 #4 Posted 8 hours ago How big a deer did you get? My 1967 Lawn Ranger upgraded to a 7 hp HH70 hauls a 750 lbs wagon load of coal up a hill in third. Traction is the issue not torque. 3 Share this post Link to post Share on other sites
