Just a large AG sprayer trying to solve weight issue. Most of this class of machine rides on wide tires pre plant for floatation on the soft ground in early spring. Then they switch to narrow tires after planting for row crop work.
Just like all things AG these days, Size has driven weights up, limiting when they can be used. In the deep blank high organic matter soils of the central corn belt, wet conditions can stop timely application, to the determinate of the product sprayed efficacy. Some times applications are skipped due to this. This can reduces yields, and increase weed pressure.
My bet is tracks will help some, but cost of operation will limit adoptions to high value crops. Commodity crops not so much. I have been on tracks will tillage tractors for over 20 years. IMHO if a track rig doesn't say Caterpillar on it, it is suspect. 100+ of track vehicles experience is not match able by any other company. Who ever built this rig will get big $$ for this option, and 3X or more for parts. It takes large production numbers to get costs down. Profitability for farms is quite low now. To many are now growing row crops in places ten years ago were not, and never had. This is causing excess production and low prices result. Federal crop insurance is available in these area's makes it attractive to do so. My bet is only small numbers are produced, unless profitability in commodity crops go up quite a lot..... Will never be mainstream till we see longer term profitability. No idea when this might happen. High value crops are usually grown on sandy soils and irrigated. Those pivot irrigators are used to apply some fertilizers and chemicals as well, lessoning the need for a rig such as this as well in that market ...
These tracks on this sprayer IMHO do not look beefy enough to stand the pounding a custom operator with a $20/hr. cowboy trying to get over as many acers per day as possible. Maintenance costs will be a pucker factor for the owner.
