Vegetable harvester and method

Abstract

The invention is a harvester particularly suited for harvesting baby greens. The harvester generally comprises a chassis with wheels that travel in the furrows between raised beds, a sorting belt assembly, and an articulated connection to a cutting assembly on a floating header. The floating header rides on the top surface of a raised bed and is articulated so that the floating header can move independently of the chassis to follow the contours of the top of the raised bed so that the cutting assembly can cut at a uniform height. The sorting belt assembly includes a series of belts for collecting and sorting the cut baby greens at the easiest and most effective time to do so, immediately after the baby greens are cut and before the baby greens are clumped in storage bins or in other storage container. The invention further includes a method of using the harvester of the invention in which the forward momentum of harvester and the density of the crop are used to assist the cut product onto the collection belt.

1 . A method of harvesting vegetables, the method comprising the steps: 
 (a) providing a harvester including a bandsaw cutting blade for cutting vegetables to be harvested,    (b) providing a field planted with a selected crop density;    (c) using said crop density and a forward momentum of said harvester to assist the vegetables to be collected by said harvester.    
   
   
       2 . The method of  claim 1 , wherein the crop density ranges between 10 and 25 seed lines per linear foot.  
   
   
       3 . The method of  claim 1 , wherein the crop density is 14 seed lines per linear foot.  
   
   
       4 . The method of  claim 1  wherein said band saw blade is positioned on a floating header that is configured to move independently of a chassis of said harvester to follow a contour of a top of a raised bed.  
   
   
       5 . A harvester comprising: 
 a chassis,    a floating header including a cutting assembly and a ground contact assembly, wherein said ground contact assembly rides on a top surface of a raised bed and at least partially supports a weight of said floating header,    a coupling assembly between said chassis and said floating header configured to allow said floating header to move relative to said chassis.    
   
   
       6 . The harvester of  claim 5  further comprising a suspension system coupled between said chassis and said floating header for reducing ground pressure applied by said ground contact assembly.  
   
   
       7 . The harvester of  claim 5 , wherein said cutting assembly comprises a bandsaw cutting blade.  
   
   
       8 . The harvester of  claim 7 , wherein said cutting assembly further comprises a collection belt positioned behind said cutting blade.  
   
   
       9 . A method of using the harvester of  claim 5  comprising the steps: 
 (a) providing a field planted with a selected crop density;    (b) using said crop density and a forward momentum of said harvester to assist the vegetables cut by said band saw blade to be collected.    
   
   
       10 . The method of using the harvester of  claim 9 , wherein the crop density ranges between 10 and 25 seed lines per linear foot.
