420 pulling capacity

[justjd420]

I have a 420 crawler in very good shape. Engine is strong and has no problem pulling two blade plow in third. I currently have a pair of offset disk (six plates in each four sections) that I pull around in third gear fully cocked. The machine has no problem pulling them. I would like to purchase the same design of disc but just a little bigger. Each section has nine plates and appear just a little larger in design. I would like to know if my 420 will handle the extra load pulling the larger set in third ?

Hi: When I was logging, we used to say "load light; bind tight."
The meaning is if you work your machine too hard and go too fast and loose, you'll regret it. Most machines have a threshhold for work higher than we might think, but exploring the upper limits on a regular basis costs downtime and money. Good luck finding the balance. Let your experience with your current setup guide your decision.

Deere says it will pull 3 large bottoms.

How wide are the disks? I'm not sure, but I think it will pull at most an 8' disk harrow.
