Need L3901 alternatives

[Cahaba Valley Farm]

Not sure on this, and it’s largely speculation, but the Kioti has orbital valve hydraulic power steering that’s run off the main hydraulic pump, and I suspect the power steering only draws flow when the operator is actively moving the steering wheel. When the wheel is stationary, all hydraulic flow is available for accessory attachments.

Older designs like the Kubota have a separate hydraulic pump used to drive a conventional power steering system, and the steering hydraulics aren’t integrated into the tractor accessory drives, thus the lower values for hydraulic flow available for accessories and attachments.

I don’t know if that’s correct, but if so, it explains why Kioti only has one number published, while some competitors have two numbers.

Is this what Kubota is referring to when they state the L3901 has Integral type power steering?

Thanks finn if that's correct it can make sense.

Don’t think so. Integral power steering is a term used in the 60s to distinguish the Saginaw power steering boxes from the earlier technologies that used a separate hydraulic ram that clamped on the tie rod to provide the hydraulic assist.
