No drive when clutch depressed on B2920 HST

I would guess this is an evolution of tractor design. Over the years the B series had gear and hydro and the L series have gear, Glide shift and hydro. It is probably just as simple to mount the engine up to a bell housing and clutch and then insert what ever transmission and PTO type inbetween. Now the BX tractor were designed fromm the ground up with one tranmission type and just have a drive shaft from the engine to transaxle eliminating the clutch (not sure but some of the newer Bs may be doing this also). Nice to have a clutch but with my L3130 with the Glide shift you do not use it very much either since there is an internal hydraulic clutch pack inside.

Have had a few hydro tractors (Bolens HT20), wheel horse 12hp hydro 1 range and there was never a clutch.

Clutch would only engage/disengage PTO!

Just thought that the "high tech" clutch block provided with the Bseries could stay in place indefinetly if not using pto.

NO problem...I'm sure that I was not the only one unaware of this feature!

I think that Kubota was cost cutting on the clutch system. I knew what I was getting into however when I bought my B2620. The three speed hydro was worth the inconvenience of the clutch system. The JD2320 and JD2520 have a hydraulic PTO clutch, and there is no clutch to engage when changing gears - it is still recommended that you lower the rpm and come to a stop before changing gears, however. The issue I had with the JD was that with two speeds on the hydro, I would have to change speeds constantly when mowing, or just be limited to mowing in low. With the Kubota, I rarely change ranges - I mow exclusively in mid. People have tried to justify the Kubota set up as if there is some advantage to this system over the hydraulic clutch set up, but if there was some advantage, then why has Kubota put a hydraulic clutch on the B2630 and B3030 premium tractors? Its a cost issue. For the money, these are great machines - if you want the premium features, then you need to move up to the premium offerings. For me, I couldn't justify the additional cost for what works out to be a minor inconvenience.

Disengaging the hydro with the clutch is a nice feature when starting the unit in colder climates!

Clutch. Didn't we know sombody named Clutch... no, it was Flutch...(pronounced floooch)

I personally, like to be able to TRY to stop all operations with either foot, kind of like when you're having a bad dream and you wake up kicking the sheets...
