Publication number: 20230301237Abstract: A chopper system for a sugarcane harvester comprises a chopper and a wear indicator. The chopper comprises a first chopper drum, a second chopper drum, and a timer. The timer has an operational configuration in which a first timer portion and a second timer portion are operatively connected to one another to coordinate rotation of the first and second chopper drums and a timing-adjustment configuration in which the first and second timer portions are operatively disconnected from one another allowing relative movement between the first and second timer portions and corresponding relative rotation between the first and second chopper drums to adjust a timing of operation between blades of the first and second chopper drums. The wear indicator indicates an extent of blade wear of the chopper upon adjustment of the timing of operation via the timer in the timing-adjustment configuration.Type: ApplicationFiled: March 24, 2022Publication date: September 28, 2023Inventors: YOGESH V.

Patent number: 11582911Abstract: A chopper system and method for cutting crop material with a rotating first drum having first blades and a counter-rotating second drums having second blades. Blade pairs with one first blade and one second blade contact one another and cut the crop material. The blades of each blade pair contact one another for at least ten degrees of rotation. The blades can have beveled cutting edges, and the blade pairs can make bevel to bevel contact. The initial contact of the blade pairs during each rotation can form a swipe angle of 15 degrees or less. The initial contact of the blade pairs during each rotation can have the acute end of the first blade contact the second blade near the middle of the beveled edge. During each rotation, the acute end of the second blade can contact the back of the first blade.Type: GrantFiled: June 12, 2020Date of Patent: February 21, 2023Assignee: DEERE & COMPANYInventors: Dusk S.
