Broke the subframe on my BH today. Starting to think I need a bigger tractor, like a case 580 or something...
I sold a TLB to a guy a few years back. He was 6'6" tall, 320 lbs and not fat. He told me right up front "you can put me in a rubber room with two anvils. 15 minutes later I'll have broke one and lost the other." He didn't actually break much and he's a super customer. But what he was telling me is to sell him the industrial $2400 box scraper, not the $550 unit, and the heaviest backhoe, etc. He bought top of the line, didn't break much and has had the tractor 7 years now. But when he latches on to something with his 4-n-1, just like when he grabs something with his hands, he expects to lift it or tear it apart. He has no low-speed or gentle mode. You don't sell a guy like that anything but the best you have.
We have sold a lot of Bransons over the years. We generally sell the Amerequip made 8620 hoe on them. We have had very few problems. Never had a subframe break. We've had a couple of guys bend bucket rams, but that is generally due to misuse or abuse. You see, when you have that bucket curled all the way in, it's ram is completely extended and in it's weakest position. If the teeth of the bucket are caught on something and you pull up the boom hard, there is no where for the oil to escape the cylinder since it is beyond the pressure relief. So a cylinder that will only see 2400 psi through the valve, may spike to over 5000 psi. If it is all the way extended, it's tough on things. A sharp shop can install a load relief between the valve and the bucket cylinder and set it fairly high. That will allow the bucket cylinder to close instead of bend.
Some might wonder why there are no load reliefs standard. It's a matter of cost and the fact that seldom does anyone bend a ram like this. If you take a valve setup on a nice excavator, it may cost more than the entire backhoe for a small tractor. And I have bent excavator rams, but I knew when I did it that I was asking for trouble since I had the pressure reliefs set a touch high. That machine would dig like no other, but over the years I bent two bucket rams. Both times ripping through roots with the bucket curled all the way and bouncing the unit a little with the main boom ram. Works super, or busts things...either the root or the ram. Eventually we set the pressure back a bit. Which brings up the thought, have they checked the pressures on your unit? They might be high.
