Getting used to the new (to me) B7510

[Rod in Forfar]

I've spent the better part of the last week getting adjusted to the '05 Kubota B7510 I picked up privately last weekend and towed home.

So there are some notes and a few questions. Feel free to comment where you have information to ad.

- Towing: A few years ago I built a tandem trailer for my Polaris Ranger and usually tow it with a 4 cylinder, 4WD Toyota Tacoma, rated for 3500 pounds. The truck/trailer combination proved marginal at best for hauling a B7510 with belly mower. In hilly country I was genuinely worried about the rig's stopping ability on the wet pavement of the day. For another trip of that duration (3 1/2 hours, one way) I will use a heavier vehicle and a trailer with brakes.

- Kubota hour meter: According to the gauge the meter counts time at 1000 rpm. So a corrected hour of mowing takes about 28 minutes to elapse. At that rate the 210 hours on my tractor are more like 100 if it has been used exclusively for mowing.

- Mid Mount Mower: It's quite an impressive implement. I spent the better part of two days on a flat garage floor adjusting the thing for a tall cut. It produces a fine mowed surface now, and the rocks are well below the cutters (ok, most of them). The vendor installed the mower by driving over it and clicking everything into place. It took him about ten minutes.

- Seat and seat belt: It's impossible to mow without the seatbelt fastened. Perhaps the tractor is designed that way. The seat is slippery enough I would fall off it on some of the slopes of our lawn, and without the downforce of the belt the tractor could easily flip me from the seat on full-speed, 500' dashes to the end of the lawn. For the record, the mower cuts very well at max. cruising speed. The mower is indeed an impressive implement.

- 4WD: The extra wheels driving make treacherous slopes easy on this machine. That said, in one terraced section I did use the differential lock to get up over the top. Seamless power in tough going, though I've eliminated occasional skid marks on corners by mowing in 2WD for the most part.

- Hoist: Is there any way to adjust things so that the mower doesn't trail along on its front casters while lifted?

- Remotes: I switched the ends to fit my log splitter and tried it. Not bad at all. The splitter seems just as fast (not very) as when mounted on my 35 hp. TAFE, maybe a bit faster. My line pressure gauge reads 2600, which seems high. I tried to adjust the nut. The lock nut came loose easily, but the inner nut seemed to be soldered to the larger round end on the housing. Is the whole thing supposed to turn? I put all of the force I judged appropriate onto the end of a 9/16" wrench and nothing moved. Perplexed.

- The Tractor: It runs very well, produces an excellent cut when mowing, maneuvers easily, provides great visibility, reasonable comfort, and an improved level of operator safety (I hope) over my elderly Bolens G174. But I still like the Bolens better. I almost never smell exhaust fumes from the Bolens, and I just like the feel/sound of the two cylinder engine better than the rather loud Kubota mill when it's running the mower. The Bolens is a friend; the Kubota is a tractor.

Congrats on your new tractor-glad you like it.

About your hourmeter-the meter records hours of operation at PTO RPM.A full hour of operation at PTO speed would record 1.0 hours.A full hour of 1/2 of PTO speed would record .5 hours,etc.

Kubota used those awful foward-sloping seats in those years.About 2008,Kubota had a B and BX replacement seat campaign,$28 and your old seat got a great replacement seat.Some dealers had some left awhile back,but they may be gone by now.The new seat is most likely still available,but at a higher cost.Maybe a call to your dealer if the seat is an issue.

Good Luck!

That's just a rumor until we see pictures!

The tractor, FEL, and MMM should have been under 2,000 lbs. You probably weren't overloaded. Perhaps brakes on the trailer would solve the problem.

- Kubota hour meter: According to the gauge the meter counts time at 1000 rpm. So a corrected hour of mowing takes about 28 minutes to elapse. At that rate the 210 hours on my tractor are more like 100 if it has been used exclusively for mowing.

As mentioned that's AT PTO SPEED. I don't know at what RPM you mow, but I've probably put 100 hrs on my B7610 and only 40 hrs on the meter.

- Seat and seat belt: It's impossible to mow without the seatbelt fastened. Perhaps the tractor is designed that way.

That seat should be illegal, get it replaced, it's dangerous.

Good luck, have fun, post pics.

I'm still stumped by the adjustment of the relief valve...

About the hour meter. Thanks for the clarifications. I didn't read the instrument carefully enough. I'll look into getting a different seat. This one doesn't suit me.

On the other hand this morning I mowed an area which I believed only my Bolens in 4WD Lo could cut, and the 'Bota did it with insolent ease.

The row is basically a pile of small boulders with a bit of soil attached, tossed up by a backhoe digging a ditch. It happens to back the 400' flower bed which runs to the road, so I have been under considerable pressure over the years to keep it mowed. When we bought the Ranger I did haul enough topsoil into the area to allow a mower to roll along the ridge without high-centering or falling into the ditch, but at considerable risk to the blades. Anyway, the Kubota with the mower lifted trimmed the stretch just above the jutting rocks and with improved safety and control.

Where are the other end of the two lines to that valve connected to the tractor??

The third line which makes a 90 degree turn toward the centre of the tractor is from a T on the outfeed line. The other two come to the block pictured just below the right foot controls.

I looked up the Salami VOM6 hydraulic control and downloaded a diagram. The nut I tried to turn in an earlier attempt is in fact the adjustment. I just have to turn harder.
