B2650HSDC. I have a B2650 tractor and specs show it rated to lift 920-970 lbs. I am using forks and not able to lift more than a 45 gallon drum of water. If I try to lift more it just stops does not go higher. I have not adjusted the presuures since purchased. I only tried lifting a few months after purchased and using in the summer. Is the lifting point calculated right at the quick attach . This is one reason I purchased this tractor is the lifting weight was minimum to what I wanted and does not even do half. Guess should get a gauge and check the presuures?? Any help will be appreciated.
