Product Questions & Answers (3)

Question by: Merle C on Apr 3, 2025, 5:49 PM
Will this motor work for a seeder application?
Answer by: Customer Support on Apr 5, 2025, 6:26 AM
This H series motor is often used in agricultural seeders, so it should be a good fit. It's also used in augers, harvesters, and even floor polishers.
Question by: Wade C on Nov 13, 2025, 10:37 AM
got a motor bracket with a 2 bolt flange already on it. is this one set up for that, and what size are the ports?
Answer by: Customer Support on Nov 15, 2025, 6:57 AM
It uses a 2 bolt mounting flange and it has 1/2 NPT ports with .500-14 NPTF dryseal pipe threads, so it matches the common 2 bolt pattern and NPT hydraulic connections style called out for this model.
Question by: Hugh W on Jul 13, 2025, 12:09 PM
what's the break-in procedure on this motor before puttin it under full load?
Answer by: Customer Support on Jul 15, 2025, 6:05 AM
Run it at about 30% of rated pressure for roughly an hour before you put it to work. Make sure the motor is filled with fluid before any load gets applied. Skipping that step can shorten the life of the motor, so it's worth taking the time upfront.
