IH 856 and chisel size

MJordal · Nov 7, 2014

Does a IH 856 have enough muscle to pull one of the smaller 7 or 9 shank brillion or similar disk chisels with twisted points? The tractor does not have the M&W turbo setup. If the 856 won't, what size tractor would? We have been hiring a neighbor with his new magnum and disk/ripper to do the fall field work for several years, but this year he might not get to us. Thanks in advance.

I pull a 9 shank CaseIH 6500 disc chisel with my 1456, and many years that is all she wants and my 1456 is turned up to 150hp.

The 856 is a legendary good tractor but you'll need at least 30 more horses. Jim

Not sure how it compares to what you're describing. But I pull an 11 shank Graham Hoeme with 4" twisted behind an 806. Does fine in 3rd at about 6 inches deep.

mjordal, I have a 966 that I pull a 13 shank 3pt chisel with regular point 8 inches deep in med ium clay loam/calachie based soil here in Central Texas. I also pull a 13 shanks drag type Graham-Hoeme with sweeps at slight shallower depth too. The 4in twisted shanks might require a few more pony's but an 856 will/should handle it unless you are in a heavy clay based soils!

And 856 with a M&W hair dryer is probably turning 115-120 horse and a seven shank with 4 inch twisted shovels will work well as long as you have a full rack of ft. weights loaded tires and duals . one other thing is tire size , if it has 18.4 x 38's or is it down on 18.4 x34's . You should be able to run first high in descent ground around 8-10 inches deep. My 806 will run a 9 shank straight shovel eight to ten inches deep but it is a three point . We are now DEEP ripping with a barn yard engineered Land Doll disc chisel that now had five DMI parabolic Tiger shanks with seven a half inch Tiger points and five or six inch upper shank shovels and going down thirteen inches or in other words five to six inches into the clay behind a 1066 that is tweaked and weighs in at around 18500 . now normally we can run first high , but Wednesday was not the case as i was ripping one ten acre field that we had chopped corn on when it was to wet in the rain and the wagon tracks in places would take you from 6-7 MPH to 0 in the blink of and eye . I had the pony power but was lacking traction and weight even with the duals .

Depends on your soil type. Around here 150 drawbar horsepower FWA tractor can be stopped with a 9 shank chisel. Usually we try to run about 7 to 8 inches deep. Tractor won't pull it worth a darn in 2wd. I would be looking more in the 5-7 shank range.
