You probably do not have a Remote on the 7100. The only planned function for the small hydraulic pump on it is 3pt lift and not even steering. Probably would barely operate a loader if at all. Thus, by the time you add a pump which is expensive and/or a remote you are into more money than the machine is worth. To me, best utilization is work it to death on whatever it is already equipped for and go to some other machine for other things. Still very nice to have around.
Congratulations on the B7100.
I love mine. Loader works awesome. It a great digger.
I put remotes on mine, but I never tried a splitter. When I do the math on the specs, it sounds both slow and not particularly strong. I recall figuring that for a reasonable cycle time you`d be limited to a 3 inch ram, which translated to about 9ton.
The loader is great for the size. It cycles fine. As for add-ons like logsplitters, you just have to think outside the box. It could be done using a PTO pump, many aftermarket loaders use them. There are tons of posts on here about these little tractors. The B6100 and 7100 are almost interchangeable aside from the engine so you can search posts for either of them
When it comes to power steering, you can sometimes find the parts on E-bay to do it. I run mine off the hydraulic pump but will add a belt driven pump to the front of the motor at some point, foreign cars have small ones with remote reservoirs. Mine works fine but I lose power steering when I operate the FEL. Seeing yours doesn't have a FEL you may not feel the need for P/S but it does keep the fingers unbroken when going through ruts. In my sig you can see my P/S thread plus I added some more below. Do keep an eye on the steering box, they are a weak link.
My friend's 7100 has PS and FEL.
What they did was to add a 2nd pump up front driven by the crankshaft via a universal joint and short shaft..
Seems his factory pump is dedicated mainly to the power steering with the aux for the FEL.
Since he suffers from a slight handicap he added a short lever to the hydro peddle that allows him to hand operate the 'go peddle'.
It seems that he is getting near 3000 hrs on it (added a recording tack). LOL it looks like it too.
His main downside is that it has a dynamo and that puts out a mere 10 amps or so but with LED's we have today he has all the lighting he needs.
Had one for a few years, used it to mow with and do odd jobs - Work GREAT and always started and ran without any issues or problems. Was good on the hills and was only 2 wheel drive but never had any problems getting around with it mowing our hills.
