Had/have a 120 on the front, 1300 on the back.


At under 900 gallons,  yes, you could go through more than self propelled, but there are trade offs.  over 900 and wet = stuck looking at the sky.

Inboard tank distribute the weight better, then you get the joy of two tanks for spraying  (not my favorite)


Low height for late season spraying is one of my major beefs......  


Sprayed allota acres with the kitty.   10-13 mph.....  No where near as nimble as a SP, but got the job done.   tracks will KILL a plant dead if run over, tires just make corn not put a cob on (;))......   Dont miss the turn ruts on the ends, but sure hate the ruts in the feild from the pizza cutters this summer  (320's are made by satan himself)........


Long story short,  track sprayers are nice..... Just plan on hiring some custom when the plants get tall......  (that is why we have a hagie now) 

Booms in the shed,  not sure we should sell it or keep it just in case....
