Dual Master 3000 iR

Integrated spin and relief

The Dual Master 3000iR combines auto-indexing relief with the legendary Express Dual spin grinder technology. Building on the technical foundations of the renowned Express Dual and Anglemaster system, the Dual Master 3000iR is the fastest, easiest and most accurate way to return cutting units to manufacturer’s specifications.

Its unique mounting system spins and relief grinds “in frame” with rapid changeover. Operators don’t waste time switching from relief to spin grinding, and mowers are ground in-situ (i.e., with bedknives or rollers in machines).
