Re: Knowing what you don\'t know...
Position control may be standard on the larger Kubotas, but it is definitely not standard, or even available, on the B7500DT or B7500HSD. The manual is very specific in pointing out the "Hydraulic Control [Except B7500DTN]" vs the 'Position Control [B7500DTN]". Based on the manual's description of the B7500DTN's "position control"; "This will control the working depth of 3-point mounted implements regardless of the amount of pull required.", I suspect that the B7500DTN may also have draft control.
Using the definitions in
this thread;
<ul type="square"> [*]Draft Control: is normally used for ground engaging equipment like a plow. It will sense the resistance being applied to the implement and raise it if the resistance becomes more than you have the draft control set for. This allows the tractor to continue its forward momentum without losing traction. Some compact tractors have draft control but it is mostly seen on larger tractors.
[*]Position Control: allows you to lower the 3pt hitch to the same height it was previously at. An example would be using a tiller and you are using your Position Control set on #3 to achieve a desired depth. At the end of a pass you lift the tiller and turn around for another pass. By lowering your Position Control lever to #3, you will be at the same depth as the first pass.
[*]Float: lets a loader or 3pt hitch move up and down with the contour of the ground. Almost all 3pt hitches do not have down force and will always float up with the contour of the ground. A loader does have down pressure but most have an additional setting to let the loader float. This is useful when driving backwards with the bucket down to smooth loose materials on the surface.
[/list] On my B7500HSD, the "Hydraulic Control" has a central, neutral position in which the hitch is stationary at whatever position it was last placed- pushing it forward lowers the hitch and pushing it back raises the hitch. To set the hich to a particular height, the lever is pushed in the appropriate direction until the desired hitch position is reached, and then the lever must be returned to the neutral position. Leaving it in the forward position will allow the implement to 'float'. Leaving it back will cause the hitch to raise fully, at which point the lever is automatically returned to the neutral position. This does not seem to qualify as position control. In contrast, on the B7500DTN, it appears that the relative position of the lever indicates the position of the hitch; in other words position control. A (detented?) position at the extreme front of the lever travel enables floating.
