Help* bobcat B300 HELP

[gaudet]

hello I have a Earth force EF4 which I belive is the same as the B300. Its a great working mashine but I am having a problem that I can not solve.
IT all of a sudden, lost its forward and reverse gears. It appears to be switching ( ie, the back up beeper still reacts)
And it appears the button clutch is working.
I have no owners mannual and no service manual. and my local bobcat deallers are so concernered with skid steers that I am lucky they will even talk to me.
Does anyone have any insite into this? I have a licenced machanic that has looked at it and feels its an electrical problem but without any more info, I don't know what to do.
ANY and all help would really be appricated.
Anyone with a B300 service mannual or a earth force EF4 mannual- I am willing to buy a copy from you.
thanks

Welcome to the forum.
Wow, I thought I would do a google search and find about 500 links but these service manuals appear to be pretty rare.

I was able to find a seller on ebay that specializes in Bobcat manuals. Here is a link to his ebay store.
eBay Store - THE MANUAL SOURCE: Bobcat B Series Backhoe: BOBCAT MODEL B100 BACKHOE LOADER SERVICE MANUAL 1

I know we aren't supposed to post links to ebay auctions but unfortunately, if you simply go to ebay and type in the store name, it doesn't come up....don't know why but it won't. (This link isn't to an actual auction, it is to a store with flat rate items)
Anyway, he has a b300 service manual in stock, I could not find an Earthforce manual.
Hope this helps and I apologize to the forum administrator if this link is a no-no but did not know of any other way to completely explain how this poster could find the manual.

I have the exact same problem. I've got over a thousand dollars in shop hours and the local bobcat dealer still cant tell me whats wrong. If you find out anything please let me know.

Update-
Got it fixxed. Took MANY months and lots of reasearch. It was the hyrostatic drive pump and the repair cost me $2500. Roughly the cost of a new one

After a lot of research and some fault finding once I had the right manual, my problem with my B200 turned out to be a simple battery charging issue. Now I knew I had a battery charging issue, but didn't realize that if the voltage dropped a bit the safety solenoid would no longer fully open and create lack of drive symptoms.

Your EF4 has a variable displacement pump and motor, so the hydraulics are quite a bit more complicated.

Best of luck
