We are working on the rotary decks for our 4500 Rotary mowers which cut almost all of the rough grass on the golf course. We currently have 2 of these machines which are 8 years old. There are 10 cutting units total, of which 4 of them have significant rust on the underside. The photo on the right shows a rotary deck in decent condition compared to 1 that is rusty. Factors that cause the rust include, age of machine, usage, moisture, fertilizer, and grass accumulation.
We will be removing the corroded metal and welding metal supports in it's place. The decks will be primed and painted to try to slow down future rust. This process will extend the life of the cutting units. With aging equipment and their usage, rust is a concern.
