Need advice on my kioti

[K man]

Well, I tried to go up those hills again and this time tried some advice from you members.
As I was coming towards the first hill in H I stopped and dropped it into M with pedal fully pushed in and started to climb the hill and has it was starting to bog, I eased off on the pedal a bit and the revs came up and machine starting to climb with less hesitation and just kept on releasing or pressing the pedal till I hit the top.
Then I stopped and changed to H till I got to the next hill etc etc. I had to put the range into L on the steepest of the hills cause no matter what I did in M the machine just kept bogging. So now I have a better idea of how the HST works on hills.
Thanks all

Yeah, it's kind of counter-intuitive, that the directional pedals are not accelerator pedals like a car. To get more power to the rear wheels you let up on them and slow down, whereas a car, you stomp on the accelerator.

Glad you're getting if figured out. :thumbsup:

Like mentioned before I have no problem working with the tractor. It just annoys me when going up hills I mean these hills are very steep and long. Unless someone is sitting in my seat at the time of going up hill then they would see what I mean. I don't think it is the tractor, the problem is the hills. I don't go down off my property very often but when I do it just irritates me of how slow it is at climbing. I have lots of patience just not use to HST power compared to gear drive.

Let me ask you this, if your tractor had an 8x2 gear transmission, and you were stopped at the bottom of a long uphill grade, which gear of the 8 available forward gears would you select to climb that hill.?

My tractor with loader installed, and loaded rear tires and my counterweight on the 3point weigh over 6000 lbs. It has about 35 horsepower. My pickup truck weighs about the same and has over 300 horsepower available. Which do you think will climb a steep grade from a dead stop faster?

Think a bit about the relationship of RPM, torque, and gearing of the two vehicles and their intended purpose.

I will give you an idea of how high the hills are. One hill is 1 mile long and I am going from flat ground to 1300 feet to the top. 2nd hill is 1/4 of a mile going from flat to about 500 feet and there are a few not so high in between. Now if you can find a hill around your area that is close to the same height and distance then you tell me how your machine performs as I am curious.

I have some very steep hills here on the roads in Branson, and my (heavy) tractor with HST will not climb them in High range very well. I have to go to Med range, and even them back off of the HST pedal to keep the RPM's up on the engine. I don't road the tractor very often, and on more gentle slopes or flatter ground, the tractor fully loaded will run fine in High range and the speeds shown in the manual. But when climbing steep hills, High range is not the way to attack them.

What you just described above is exactly what I do with my H/M/L HST B2650. If it is more than a slight slope up on a paved road, I will drop into mid range. Sure I could back way off of the HST, but it whines loudly and I can imagine the heat being generated from the HST slip/bypass in that condition. So instead of slipping the heck out of the HST system, I drop to mid and push up the hill, then stop and go back to high range to push the level or near level areas.

It sounds like your machine is acting as expected and you now understand the limitations of the high range. It is in no way, shape or form a gear range for doing any work aside from moving the machine across relatively smooth level ground.

1300 feet up in 1 mile is a 4:1 incline. For every 4' forward you are going 1' up.

A 1:1 slope is 45 degrees, and 100% grade.
A 2:1 slope is 22.5 degrees, and a 50% grade.
A 4:1 slope is 11.25 degrees, and a 25% grade.

That is a very steep angle and grade to try to go up in high range and hold speed.

One thing I didn't see you write was what you are doing with the throttle. Several people asked if you have it at full throttle or not, but I did not see the answer.

1:1 slope = 100% grade = 45 degrees
1:2 slope = 50% grade = 26.5 degrees (arctan(0.5))
1:4 slope = 25% grade = 14 degrees (arctan(0.25))

Grade = rise/run
Angle = arctan(grade)

1:2 slope = 50% grade = 26.5 degrees (arctan(0.5))
1:4 slope = 25% grade = 14 degrees (arctan(0.25))

Grade = rise/run
Angle = arctan(grade)

I should have consulted the old math there, eh? hahahaha

Or used the convenient chart.



That's why I don't like using grade for describing an angle.

This is the one I don't care for in Pittsburg.... Canton Ave.

20 degrees and 37% grade.

We have a lot of them around here that are steeper. This is one thing I hate about this area.

My wife and I were down there last week. We drove from here to Hannibal, MO, then down to Mark Twain State Park, Columbia, Rock Bridge State Park, Osage Beach, Lake of the Ozarks State Park, Ha Ha Tonka State Park, Bennet Spring State Park, Branson, MO, Table Rock State Park, Eureka Springs, AR, Bentonvill, AR, Crystal Bridges Museum of American Art, 4 casinos in Oklahoma, back to Branson for the night, then over to Cape Girardo, IL, another casino, Trail of Tears State Park, down to Cairo, IL to see the Ohio dump into the Mississippi, and back home.....

Yes, you do have steep roads down there! :laughing:
