I have a friend that has one on his Cat 420 & he let me use it for a month. I've never used one before that but enjoyed the features I was able to utilize.
Okay - we have some commonality in that our knowledge of 4/1 is limited to commercial TLB's.
The Cat 420 could probably pick up your L3901 with the 4-in-1...won't work the other way. The Cat probably weighs 2-4 times the L3901, depending how equipped.
It has MUCH more horsepower, hydraulic capacity/force. It’s comparing apples to oranges.
Heck, a little B26 Commercial Kubota TLB can pick up my BX2360 easily...
Just thinking I wouldn't expect the same performance from the L3901 with the 4/1 that you experienced before.
150 pounds could be a real issue with an L3901; you aren’t realizing that yet due to your seat time in a commercial TLB.
Again, not a lobby for/against. Just want you to be informed and forewarned.
