Subject: murry pull strength? Sun Oct 13, 2013 10:51 pm
hey guys, I have a 1996 murry with a 12hp briggs and want it to be able to go through snow and have lots of torque to pull heavy loads, how can I accomplish this?

The snow part I would have no idea, but I would think you'd need a lift to go in it and some better tires off a 4 wheeler or something, and of course a pulley swap. You can watch some of feerlessfronts videos on youtube and find out more modifications for snow and water. For the towing part you should be able to tow heavy loads now then you could with a pulley swap. But if the loads are really heavy its gonna stress your transaxle and possible crack the cases.

Budget, tools and skills aside, here's what I would do-
Get rid of the transaxle in favour of a 1 1/4" solid axle and separate transmission, such as a Peerless 700. This will give the rearend massive strength and eliminate the differential, greatly improving motive force in the snow.
Since this will result in a chain final drive, you can use both the pulley ratios and final sprocket ratio to fine-tune the overall redux ratio. You can end up with a decent transport speed, and yet plenty of torque.
Snow traction can be improved with ballast weight, aggressive tire treads, tire chains, or a combination of these.
I've pulled upwards of 2000lbs with MULE, and it didn't break a sweat. As others have mentioned, just watch your tongue weight. Pulling is one thing, taking a load directly on the rearend is another thing.
I've seen one of the videos of Stretch moving a camper. Dead funny, especially considering he had to have his son (I believe) hanging off the frontend of the tractor as counterweight!
