Power Steering in 90 Minutes!

   / Power Steering in 90 Minutes! #31  
My late model B7100HST only has one pump that supplies both the TPH and the FEL. If I do this mod, am I always losing 1.5GPM (of my paltry 3 GPM), or only when steering?

Has anyone ever upgraded the built-in pump on a B7100? It would be nice to have more. This limitation also prevented me from considering a three-point log splitter, as the cost of adding a PTO pump made it cost more than a good stand alone splitter.

Hi Jas!

Yup, I'm in the Boston area, too bad, I'd do your for free. It's a fun project. The name come from when I worked at a Boston radio station (WBCN) that had rats out back. We got USDA smoke cartridges from Agway, Victor traps, poison, ammonia in pump up sprayers, and more. "Rat Patrol" was so effective that I pushed them back past the hotel next door. The local nickname for them was "Kenmore Kitties" since we were next to Kenmore Square & Fenway Park.

But back to tractors, you really need a pal in the area that can do "fab". I honestly took only 90 mins here and I had a few delays. If you have the hydraulics figured out the fab is easy.

As to hydraulic loss, it should be minimal when not steering. You can either use a priority valve or see how KubotaNH makes out with it in series. The guy we got ours from says it will bypass 3.5 gal per min. The issue is without a priority valve you will share the 3 GPM for the FEL and steering and the one that has least resistance will work before the other will. We kinda feel that you don't steer and lift/tilt at the same time too often and might get by with a series circuit. I don't think you need too much GPM for the steering to be honest, the tube from the actuator valve to the cyl is tiny.

All I can say for sure is that if you do it and it works, you will be out of your mind happy.

Best to you and all the hot babes in PA. (I've been there, what's going on with all the good looking girls??)

What's going on in PA? What do you use your tractor for?

Bostonrats -- that is a funny story -- LOL! It could be worse;
ever hear the joke that ends with "two dogs f???????"

I have a co-worker that does fab work. He doesn't work for free,
but is reasonable. Last year, I traded tractor work (box-blade
leveling of some dirt) for fab of my box blade tailwheel. I should
have had him do the tailwheel first -- would have made my part of the
job easier.

As for tractor work, I only have a 1 acre property, but we just bought it 2 years ago, so I've actually had quite a bit of opportunity to use it. It may be small, but if worked within its capability, a lot can be done with it (as you know). We put up a pole bar, which required excavating back into a slight hill, so we put up a retaining wall, so I had a bit of ground leveling, and backfill to do. We put of 350' of split rail fence, so I got a 3pt post hole digger for that. I didn't do as much snow removal as hoped for (total of less than a foot this year, normal is usually 3-4' with at least one of two > 10" snows). I didn't even put the snow blower on it, just used the back blade, as the deepest one was 4". Now, I'm working on next years firewood, so it has been a big help with firewood.

I was able to make a relatively neat pile with the help of the FEL (the logs range from 8 - 18" in dia, and the pile is 6' high -- I wouldn't through them up there by hand). Next step, is I'll be making wood cribs out of pallets like the ones that I saw on another thread on here. I'm getting a pin-on pallet fork setup that replaces the bucket so that I can load the wood right from the splitter onto the cribs, and then drive 'em around back to where they're going to be left to season. Then, after they season, I can drive them to where the covered storage is, and then ultimately load one crib at a time, as needed onto the back deck, near the door. This will save a lot of re-handling of individual pieces. The wood cribs are only going to be 4' X 2' X 3 1/2' high, to keep the weight within the 680lb capability of the Woods DuAl 145 loader that I have.

I'm also going to add hydraulic remotes and a hydraulic top link soon. That will help with adjusting the tailwheel, and also to provide tilt function for the carryall. Then, I might be able to use the carryall to move the cribs instead of the FEL, thus putting the load on the much-larger rear tires (to reduce wear and tear on the lawn), and make it easier to maneuver the cribs into position. I'm not sure the 3pt on the B7100 has enough oomph with green wood. It might work for the seasoned wood.

So, with the purchase of the forks, and the parts for the remotes, the power steering will have to wait until next year. I'll definitely keep this thread bookmarked, as I'll probably do the same as you have.

As for girls around here? I haven't really noticed that they are that many more, or better quality than anywhere else. The "girls" in my life are my lovely wife (who puts up well with my tool "problem", my four year old daughter, and my trusty 8 year old black lab).

How 'bout you, what do you use your tractor for?

Hello to all!

So, an upgrade to my Kubota L185DT from "Armstrong" to power assisted in 90 mins? It's true, except for the time spent getting the hydraulic hose.


This kit appears to be similar to what Kubota offered for my B8200. Mine does not have it... I did look in to it a few years ago; it was something on the order of $1250+.

As another poster noted, my B8200 does not have a lot of hydraulic capacity. What net affect have you seen on the loader and 3pt hitch? That is what worries me... running the loader, 3pt, top/tilt, and then this...

Otherwise, I want one :D

Hi Jas!

First, I've seen some VERY pretty girls in PA. Not sure why but it seemed like you had more good looking girls than we do. Of course I'm pretty close to Maine. I figure when this country was settled the babes just wouldn't go to the northern states. Could also be from years of eating woodchucks and possum. :)

How much did you pay for the wood? I'll post my 2006 load below, I'm looking now, one guy said $650 and I heard the other guy was $800. There was a cheaper guy but he's not called me back many times now but did sell me the load in the photo for $450, it had lots of nails in it but I didn't mind for the price.

On the joke, yeah...the on Charles used to tell all the time was, "I'd be your father but a german shepard beat me up the stairs" Radio was fun, I got to meet the Beach Boys, Elvis Costello, Martha Davis, Glenn Tilbrook, and more. All very nice folks. (except Mike Love was a d**k)

I use the tractor for EVERYTHING! My motto is, "NEVER GET OFF THE TRACTOR" If you ever worked where they have a fork truck you'll know what I mean...it's like you get glued to the seat. ie; you have a 3 pound rock near the job. You spend 5 mins trying to scoop it up in the bucked when you can kick it to the moon with one boot... Did you see my Frankenblower posts? YouTube - Revenge of Frankenblower!

Nice job on the pole barn, I'd love to make one some day..the other thing I really want is a 2 1/2 army truck to put in it.

Best to you!

Hi Robert,

I have a pump just for my FEL up front and use the PTO tap for my steering so I don't have any loss. KubotaNH is more like your setup, he's going to have his on soon and will be able to speak to sharing issues. Kubota did sell a similar kit, they don't make them any more and yeah it was expensive. My guess is that the steering does not take much to run, the lines from the actuator valve to the cylinder are about 1/4" OD. Rick at the steering place could also advise, he's a really good guy. (no I don't get a kickback...but would take it if offered! :)

I couldn't be happier with the results. It's so nice you forget the old days right away. Smooth and flawless. If you can make it work you'll be VERY happy.

Thanks for the post and best to you!

The load you see in my pix was $450, delivered. The cut pile isn'tall of it, I had about 3/4 of a cord split and stacked out back when that was taken.

Yes, I definitely try to use the tractor for everything, including some things that might take less time to do manually.

I'll have to take a look at your frankenblower.

You fellas can look under P/S B7100 / B7200. Some other ideas, you may like. I keep telling people that whether you are turning the steering wheel or not, the p/s uses 1 1/2 gpm so whats left will go to the other hydraulics and probably work slower. You simply cannot steer and expect the fel to speed up.

When the wheel is turned, and the steering linkage activates the valving, doesn't the cylinder move away from (or toward) the linkage? I should think the cylinder should almost be reversed, so the cylinder body is fixed and only the rod moved the pitman arm. now, you guys have done it and I haven't and I'm probably wrong, but doesn't it sound reasonable?

Shouldnt the cyl body be connected to a fixed point? Am I missing something?:confused: ............Oh, I see. I guess those hoses get a workout.

I agree[d], but when you think about it it has to be that way so the steering wheel can turn in the natural way to follow and "control" steering. :thumbsup:
