AR-522


The new AR-522™ rotary mower by Jacobsen® couples the improved class-leading performance of the AR-5™ with our revolutionary new TrimTek™ cutting decks. It is ideal for intermediate golf course roughs, green and tee surrounds and can also be used in regularly maintained sports turf and park and recreation environments.

  • Revolutionary New TrimTek Deck - Exclusive downdraft blade keeps clippings suspended longer for exceptional mulching results
  • Three-tiered Discharge Opening - Exclusive design distributes clippings more evenly for a superior after-cut appearance
  • Increased Deck Volume - Allows the AR-522 to cut in more severe conditions
  • Best-In-Class Traction Capability - On-demand control from the operator station
  • Superior Climbing Performance - More horsepower per width-of-cut than any mower in its class coupled with the new and improved decks and climbing system
  • Easy to Use - Converts from discharge to mulch in minutes with a single wrench
