Awesom video
You are enough of a mechanic for me!
Good job Paul. I thought your video was very well done. The way yours is working now is the exact same as mine. As soon as I get the time I'll get in there and root around to see what's causing this. Mine has never worked any different than it is now. Thanks for posing it. Gives people a better understanding of what the system looks and works like. You got a new subscriber ;)
+Paul Short Thank You for the nice compliment and subscribing. I was just happy someone watched it. I would like to know more about what Kubota says on how it is suppose to act. I understand the need for some cushioning when braking backwards. I'm always reluctant to have government involved. After all they brought us gas cans you need 2 hands to open and still can't pour. Have a good night.
UPDATE:
I readjusted my HST pedal settings. Had adjusted it with too much force from the damper, I decreased that force. See HST Control Linkage under (Transaxle) page 2-M8 in the workshop manual. Didn't do any further adjusting. other than what I had done prior to the tensioning spring.. Stopping in less than 10 ft. with less aggressive pedal response. Drives comfortable like when it was newer. I'm happy. See this link for the final adjustment. th-cam.com/video/rMp3m0mPIh8/w-d-xo.html Then move the time line in the viewer to 6.00 minutes. Hope you watch the whole video.
Nice detail. Too bad Kubota don't tell you where the "coasting" relief spring is located. This would change rate of stop. FYI, I found one on my 2005 Kubota RTV (hydrostatic trans). With foot off pedal, it stopped so fast people were grabbing the dashboard - unnecessarily aggressive. On the transmission I found a small (15mm?) screw cap and under that was another nut(10mm?)+washer on a bolt. Under the washer was a spring under tension. Tightening the nut would increase the pressure on the relief valve and increase stopping rate, backing off was the opposite. The adjustment was years ago and I have not had to revisit it.
Good video Paul. I have to edit one myself of just how mine responds. I have not done any adjustments, mine stops more abuptly in reverse unless I am just slowly backing up.
Thanks!
Hey Paul, great video. i currently having the same problem with my HST pedal where it has gone really sloppy and doesn't stop when you release the pedal ( it releases partly and then drives at a slow speed by it self) and wondering what other factors can contribute to this? the transmission has new oil and filter less than 70 hours old and i have geared up the grease nipple. any help is muchly appreciated
Hi Paul, my new BX25D-1 is the exact opposite than yours and Paul Shorts, it stops good in reverse but keeps rolling too far in forward, I haven't had time to take the deck off to do much adjusting yet. I'm looking forward to 4 shorts video also. Thanks for the vid. Ken
+Kenny Brown If your BX is under warranty, I suggest you have the dealer adjust it to your satisfaction before You start working on it. See what they say. Ask them what the problem was. If they come to the house for service, watch what they do.
My 10 yr old 2360 has the opposite problem. Let up on the reverse pedal and the tractor comes to a jolting stop. Dealer says it was designed that way, the only solution is trade it for a newer model.
To james ebrahimi Your settings may not allow me to reply so I'm doing it this way (Assuming the problem is only in reverse.) Does it keep coasting or is it being propelled by the transmission?
Ex going backwards up a very mild incline, when you let off the pedal, does it continue climbing up the incline or does it stop from gravity? Do You have a workshop manual?
+Paul Sargent thanks for the reply, it does climb up hills slowly when its meant to be in neutral position, it also does the same thing in reverse, it is being propelled by the transmission, ive got the Manuel but it doesn't say much about how to fix the problem part from to take it to the dealer which will be very costly.
i was under the tractor last night and found that the bearing where it is attached to the tensioning spring has slipped out of the V shape plate that neutralizes the transmission, im planning to use a pry bar and bend in back a couple millimeters and hopefully that solves the problem.
you check your fluid level??????
If does seem like a safety issue. Not good on this expensive a machine.
