706 capacity

Mgroshong · Dec 20, 2017

Hey guys, I'm wondering if my 706d (d282) is able to pull an IH 4 bottom plow like a model 720?

Also is there a general rule for chisel plow and disc widths for a given horsepower?

Btw I'm in the West central MN area. Unsure how much my soil will play a part compared to other areas.

Thanks

There are formula's out there as I remember doing calculations in an ag engineering class at Cornell. But the best indicator would be to talk to neighbor's with similar soil. On consistently sandy loam you could probably pull 4 X 16 at a depth of 8 inches at a speed around 3 miles per hour. Maybe more depending on how fresh the engine and tires are. Any way to try this plow out before you buy then you would know for sure and have some level of satisfaction? If you ask over on the Red Power board take some of the answers with a grain of salt. Most of those guys are pretty level headed but there are a couple vocal guys over there that will have you thinking you can pull a mountain while some other make will have its hands full just traveling down the road with that plow.

I own a 720 5 X 16 SAR plow so I have some experience with that model. I pull it with my 986 not that we do much plowing in current times.

In the Goodhue mn area we could pull a 710 4-16 with a 560 with weight up front. 10 hp per foot straight chisel plow with twisted shovels rule of thumb there.,(I took shanks off to seven for my 706). We pulled
a 7 shank Glenco soil saver with the 3688(120hp) easily on most of the ground and then had to shift down. Hope this helps.

I pulled an Oliver 4 16 trailer plow with the one I had.

I've got heavy black gumbo on my farm here in s.central Mn. I pulled 4-16 with my 706. Hung lots of weight on it though.

The neighbors big tractor for a lot of years was a
706 diesel he farmed 350 acres with it and a 3020
John Deere Diesel he pulled a 7 chisel plow over
everything that wasn?t in hay every fall . Then he
bought an allis d21 and a 14 foot chisel plow but
after putting 3 rear ends in the d21 he parked that
and bought his first cab tractor a 4450 John Deere
he?s only had a cab tractor for about 5 years now

10 hp per ft, i should be around 80-90 hp. So it might be pushing it with a 10 ft chisel. I want to avoid duals if I can but as it sits in 8ft wide tire to tire with 18.4/34s.

Any opinions on running 16.9/38s vs the 18.4/34s?

I know most do not rave about the durability of the d282 but I have never had a problem so maybe I can look into turning it up if it isn't already.

Thanks

Unless your 706 is turned up the drawbar horsepower will be more in the mid-60 range so a 10-ft
chisel might be pushing it a lot. A lot of it depends on your soil conditions. My wife's uncle
pulls a 12-ft chisel (barely covers the duals) with his 95 drawbar hp 986 and it gives that tractor
all it can handle in the tight gumbo soil we have around here.

Soil type plays a big role in the equation. Here a 706 was typically hitched to 4 16? bottoms. A 10? chisel plow is probably going to be too much
to pull deep and fast enough to do a good job. That chisel plow is more suited to an 806.

I was reading in the tractor shop mag one time, MM recommended using a smaller plow and going faster over a bigger and going slow. I would have to agree with that, if in
doubt, get a three bottom and up a gear and should do a better job.

With my 706 gas I pulled 4-16"s Oliver pull type plow in a sandy loam from 8 to 10 inches deep. I pulled a 14 FT. John Deere wheel disk. The tractor had 18.4 X 34 tires.

I ran a 4-16 plow in my heavy soils with an 85hp tractor, as it got older it got too weak to pull it.

I pulled a simple 2 inch 10 shank chisel plow with the same tractor, it worked but a little slow and shallow for the chisel action one would like.

I put a 3-16 plow behind my 60hp tractor and it works good. So that is 20 hp per bottom.

A disk, in fall a 20 foot light disk pulls easy with the 85hp, in spring soft ground it would be a real workout, and not enough traction without
duals not a good match.

Your ground is west of mine, a little lighter so,it might work for you.

But if it doesn't, then you either aren't getting the work done, or you busted something in your tractor...... I'm not sure why people like to pull
everything their tractor can, plus 2 more feet of width. It must the male thing, we just want more power.
