4720 Capability

[farmboy12]

Not looking, just wondering. Could a 4720, with the 58hp, loaded R1s, loader, and cab, which, put together would = very heavy. Do you think this tractor with eHydro could pull a 12ft disc in low range? Thanks!

I'm guessing that you are going to get a lot of responses that basically boil down to: depends on the disc and depends on the soil.

With a light disc, set conservatively, in loose soil it would probably pull fine.

Heavy disc, set aggressively, in unworked soil -- Welcome to spinsville.

Probably medium set, medium weight. Worked ground. We are looking into a few (15) acres of potatoes. So we don't to to plow every year, because of the middle-buster used to dig potato trenches. Just enough to get ir looking nice and easy to work with.

Can you get it without the hydro? Not the best for heavy, ground-engaging work. If not, you could probably drop down to a 4520 with gears and get a little more useable hp to the ground.

I have a 8' Deere disc that will spinout my 10k lb crawler on heavy clay sidehills. Also have a 8' Deere cultivator that will spinout my 10k lb 55pto MFWD tractor cold in light mud.

Remember tools are designed to run 3-5 mph any less and you may be wasting time.

Read the owners manual concerning extended heavy load operation.

Thanks for the info!

I may be able to, but we're not really looking right now. So, it's pretty much just what we find.

Nope. Maybe an 8' then again depends on soil conditions.

There seems to be quite a bit of difference between disks also. I recently picked up an old JD, 8 ft, pull-type disk that pulls easier than my 7 ft, Ford, 3 pt model. It also does a much better job with each pass. My 4120 can actually pull the 8 footer, set at the steepest angle, at about 4.5 mph over plowed ground, with the trans in 5th gear and the engine at idle speed. Since it aint a real good idea to work diesels at idle speed, I shift down to 4th gear and crank the throttle up a bit to maintain 4.5 mph at a little higher throttle. Without a doubt, the 43 hp, 4120 could handle a lot more disk and I suspect a 10 foot pull-type would be just about right.

I do no think it will unless you have flat ground and fluffy soil. I spent 4 hrs today on my 4720 pulling a 3pt 7.5' disk in B range at about 3.4-3.6 mph. This was under a power line and I do not think the soil was ever disked. It was a mix of red clay and darker soil and major roots/stumps.

I was a little mixed up in my gears on the previous post. The confusion resulted from using it on three different tractors in the last couple weeks. The 4120 actually pulls the 8 ft pull-type disk at idle in 8th gear, or 1/8-1/4 throttle in 7th gear, both at 4.5 mph (verified with gps). A 3-pt model generally will take a little more hp because the hydraulics is drawing some. After using this pull-type disk this spring I doubt I will ever use my 3-pt again unless I get a breakdown. The pull-type is so much more efficient with less power required and a better job on each pass. I do have completely flat land, and there is no doubt that hills will cost you quite a bit of hp pullling a disk of any type.
