Anhydrous Toolbars

[iowafarmer20]

Was wondering if anybody here has had any experience with a tool bar that only has a disk blade used to inject instead of a shank? What are the pros and cons of both? Currently looking at a caseih toolbar a 920 that uses just blades

I would be concerned with injection depth as well as covering ability, especially in wetter soils.

What JMS said, in my typically wet clay soils, but prhaps I'm just resistant to change. :)

With a shank the soil fractures a bit, the gas can follow the cracks, and lose dirt falls back on top to seal some.

Does the disk go deep enough in your soil type, are their cover disks to seal the slot, and forth.

'Here' I see the blade used with liquid setups, haven't seen it with NH3.

if you got ideal conditions they are ok , seen 1 work got to wet spot in field and could see vapor 30 ft. back , heard they take lots of hp also

Our co-op did some custom work with a 2510 Deere when it first came out. They called it a "Hi-speed" applicator. After riding with the guy running it who happened to be a buddy of ours, I wasn't impressed much. If conditions weren't perfect it wouldn't seal, if you got over 4-5mph and the units got to bouncing it wouldn't seal. Then we had some corn go down in that field late in the season due to poor brace root depth. Whole plants went down with root balls attached in October. Not sure if it was related but didn't have problems anywhere else with that number corn where the NH3 was applied with a shank applicator.

Coulter wheels are best for No-till, & minimum till. The only time I didnt brake something on a kniffed toolbar was in conventional tilled ground.
