Great question. We have 3 different lifting systems for the RS1000, so the ratings will vary. The buckets that are offered vary as well for each lifting system. The BM13 Bucket mouth for the MFH15 Manual Front Hitch is rated at 330 lbs. The BK44 Bucket and the BK45 Bucket, which are used on the HFH15 Hydro Front Hitch, are both rated at 350 lbs. The BK295 Bucket, which is used on the HL295 Loader, is rated at 400 lbs. and has a breakout on the bucket at 700 lbs. The HL295 Hydro Loader has a breakout lift of 1,000 lbs.
