I went with the one arm loader for a few reasons.
1) cheaper cost - due to half the cylinders and less steel the price is cheaper for the single arm.
2) I had hoped the single arm would run off the tractors hydraulic. While it does, it wasn’t perfect. If I didn’t have a two spool valve on the tractor I think it might have worked better. Loader would still be tough on the tractor hydraulics.
3) I really liked the single arm mounting setup. It actually slides off pretty easily to the side.
4) I also felt the single arm loader was better sized for the tractor.
She needs more "junk in the trunk"....add some more rear weight and you'll be surprised!!! my loader has 350# of cast, 200# of it on the 3pt well to the rear, and 150# of fluid in tires. Picks about 600# safely
I haven’t noticed any. The loader is connected to both sides of the frame and it appeared to do as it was it designed. The stiff loader frame seems to transfer the weight onto both sides of tractor frame pretty evenly as long as the bucket is evenly loaded.
