Not offended just annoyed by the automatic statement of it's not going to work with no explanation as to why or what exactly isn't going to work. I thought this was a discussion forum. And for the record I don't think I'm very smart. Don't have time to argue with you. And in the end you may be right. Or I'll just say it now and get it out of the way. You are right.
I see a few potentially attractive benefits to this system.
I found another 1 year old discussion about this very topic. See below link and read as it has more details on how these pumps work.
Here are the reasons why I think it could work with trade offs. Also mentioned very well in different forum link below.
1. For the B7200 specifically because that is what I drive, the first benefit would be to eliminate all the steering wheel jerking around from hitting bumps, stumps and what not on rough terrain. Just used bush hog with loader for the first time on last night for a good two hours. Wrist was sore from all the jerking around the steering wheel does from loader weight and bumps. I do use both hands to alleviate that issue but doesn't happen all the time. This hydraulic unit keeps any back lash or would prevent a lot of this phenomena from happening from what I understand.
2. I measured lock to lock on my Kubota last night. It has about 1.75 turns lock to lock.
These Helm pumps come in anywhere from 3-5 turns lock to lock. So while there is a trade off here, and I would look for no more than 3-4 turns lock to lock, I would be utitilizing/benefiting from the hydraulic pressure I do get from turning the wheel making it a little easier to turn. I looked up the standard average Lock to lock wheel rotations on a tractor and it came in at anywhere from 2-5 rotations. I'm thinking I wouldn't want more that 3-4 turns.
2. Cost. Maybe at one time this was a cost prohibitive item so nobody even considered trying it. With china stuff out here now like Vevor is it really that cost prohibitive? Or getting used on marketplace? I know american stuff like Sea Star is high $$$$$ I see people dropping 2-3K on disks and rototillers. What is expensive nowadays? How much is upgrading the steering worth? I think that is up to the individual paying for it.
3. I took a closer look at the steering set up on my tractor last night. I have a spare B7200 tractor for parts I just got. I could mock this up on there fairly easy I think... I've got a good idea how I'd try to do it. Going to the boat marina tonight to try out these Hydraulic helm pump steering units. I want to know and feel first hand how they work and see if I'm waisting my time or not. I know the owner and he said he wanted to show me a new Electric steering system they are using now that works great. I'm sure it's high dollar though. I'll find out.
I highly doubt anyone has tried this on a b7200 specifically or even a B7100. Would love to hear results if you have.
Would I try this on a bigger heavier tractor? No.
Am I going to try this anytime soon? No. To busy trying to finish my FEL up. Maybe after that.
Do I need power steering on a b7200? No.
I understand now after doing some research this does not work like an external hydraulic pump or an electric pump but it is a unique type of hydraulic pump. Could be a big improvement on the B7200 steering experience for not a lot of money. Or not. Looks fairly easy but I have not done it. Nothing is as easy as it sounds usually.
I've seen the arguments for electric pumps and external hydraulic pumps. Not interested in those options at the moment.
Check the link out below if you have time. Brings up some good points about a helm pump and probably bad too. Either way interesting read. I'm not the only dummy that thinks this could work.
