Rollover b7500 vs b7800

Anonymous Poster · May 12, 2003

I currently own a kubota b7500 and was thinking of upgrading to a 7800 or a 2910. I want to upgrade because I need more tractor to pull my manure spreader. My 7500 is very stable on the hilly terain that I own. I was wondering if the 7800 0r 2910 would be more prone to rollover. The center of gravity is about three inches higher in the 2910 and 7800. Here is the specks---7500 lenth 90.6---Width rear tires 52 ---wheel base 59---ground clearance 12.0---tractor weight aprox 1400 lbs. 7800 or 2910---Lenth 99.2---width---53.8---wheel base---65.6----Ground clearance 14.6 tractor weight aprox 1700 lbs. If I upgrade will the new tractor cling on my side hills like the old? I was thinking of getting the industrial tires. Are they a good choice for hilly terain. Will they be ok in the yard? My 7500 has loaded tires now not actually turf on the back---they have a zig zag pattern but turfs on the front. I plan to load the tires on the new one. Does front weight help or hurt you. Thanks for your input. Glenn---central PA /forums/images/graemlins/confused.gif

How steep is your hill?Loading the tires does quite abit to keep them down.I talked to a dealer about loading the fronts and he said he only has done that once for a guy who pulled a lot of logs.It tends to wear out your front end if you load the fronts on a 4wd.all these new compact tractors are pretty stable compared to what Ive been running.A heavy tractor would less likely be pushed into a dangerous situation by your spreader also.

I forgot about the tires.I have only run ag tires.I am not an expert on the subject but I would feel more comfortable with the added traction ag tires offer on a hillside.However aren't industrial tires smaller? so they would lower your center of gravity if they are.The industrial aren't that bad on the yard espescially if you take it out of 4wd when you don't need it.

I live in central PA right in the center of the allagheney mountains. We have about 20 acres of open land that is yard and horse pasture. It is rather hilly some spots are steep and some are just rolling hills. I would guess we have some 40 degree slopes. Thanks for your input. I like your thought on a heavier tractor. Im new to this site and I really enjoy it.

I got an email from a fellow on TBN that has two Kubota tractors. A BX22 & a B2410. He told me the BX22 was much more stable on the hillsides. It has a much lower center of gravity. Also lower profile tires than the Ags on the B7500. The downside is the lower the center of gravity the more chance to get hung up on rocks & ruts. All tradeoffs. I went for the BX22 because I have steep hills that I am not wanting to roll down. I think straight up & down is the best way to stay upright. Or maybe back up and mow down the hills...

Glad to hear the B7500 is stable on hillsides, I was thinking of buying the BX, but the ground clearance was not good enough because of all the rocks where I live along with steep hills that most end up in the water. Do you have the HSD and does it work good on the slopes.

I've got a B7300 with HST and pretty steep hills. The height on mine is pretty close to a B7500. I have loaded tires and don't have too much trouble. The HST works well on the hills - I run out of traction before running out of power in general.

The other nice thing about HST is that I can power up a steep section nice and slow without any jerking that might otherwise cause me to hit a bump a bit too fast. Works well for me...

kubotachief,

I grew up on a farm in the allegheny mtns of PA - used a JD 420 for years then we got a JD 1020 both 2WD with the typical attachments like a baler, and a wagon loaded with hay coming down slopes I probably would not do today.. In any event to your question.

The 7800 due to it's wheel base and using loaded rear R4 tires would make a good setup for descending or climbing most slopes, with a mower or 3PTH attachment. When using any drawbar implement like a spreader(or a baler & wagon with hay) these can get out of control if the weight of the pulled device is greater than the tractor.

So, load matching to the weight of the unit is important. Also if you are pulling a manure spreader, how is it that the manure gets in the spreader.. I think an FEL with removable bucket (for manuverability and forks) would make a very nice companion to the 7800 and add some weight to the front end as well.

Yes I do have the hydro. I am very happy with it on the steep side hills and the 7500 will cut grass!!! It doesent scalp and does a great job. I have my 7500 listed in the classified to sell because I need a bigger tractor to pull a manure spreader. If I could give you one word of advice it would be to go with the 7500 and not the bx series. You get so much more tractor for your money and they are comfortable and built tough. I like the hydro and I wouldnt even consider buying the gear model. Good luck. Glenn
