82 attachments in our database need no PTO power: box blades (22), rear blades (15), landscape rakes (14), grapples (13), pallet forks (7), bale spears (6) and land planes (5). Of the 76 that list a weight, they run from 65 to 1,225 lb, with a median of 294 lb.
These are the simplest to match to a tractor. Rear-mounted types are checked against the tractor's 3-point lift at 24 inches behind the lift points. Loader-mounted types are checked against the loader's coupler and lift instead, and grapples also need a third-function circuit.
Below is every non-PTO implement in our database. Compare the implement's weight with your tractor's lift rating.
