Hydrolic speed difference between a 810 vs. 8611LP

    I am looking to add a 8611LP to my fleet; however, I have heard that the hydrolics on the 8611 is a lot slower response than the 810. Does anyone have have both units and can compare their preferences between the two blades? I already know the physical spec's, but I am looking for peoples personal opinion. Or is there a "fix" for the slow hydrolics on the 8611?

    I think they are the same pump.... The 810's aren't exactly speedy, but I can imagine with the same pump the bigger plow would be slower. Upgrade the pump to the full size 8611 pump and you'll get faster responce.

    Newer 8611 and 8611LP use the same pump. Speed difference is the larger angle and lift cyls.

    My dealer metioned to me how the 810 was definately quicker than the lp as he switches out depending on what he has on hand.

    Running both and what Jerre said.

    I did upgrade the pump in the 1st run LP to a 8611 pump to match the newer LP. Where you will see some improved reaction times, is when you put a 8611 pump on an 810. Then thing move alittle faster but FWIW nothing that would make you want to spend the money just because have done it as part of a replacement of failed parts.

    I hate to say speed as no Blizzard plow is as fast as a Western, Fisher, or whatever, IN OPERATION SPEED THAT IS, but as Jerre metioned about Cyclinder size just look as the angle/lift rams on them other plows.

    In my experience with running the LP's in the larger lots out in front of dump trucks you are not really looking to break landspeed records you are looking for consistant production times throuhout a wide spread of snowfalls. This is what I see as a added benifit out of the 8611LP.

    Man can you move some snow when you are using a F-350/810 to feed piles to a F-550/8611LP. Sure does make fast work of it.

    On the older 810/8611's that run the Fenner pump and motor there is a HUGE upgrade but you have to do the pump AND motor and upgrade the power and ground wire as a complete upgrade. Most guys here do it when they fry a motor as it's the most expensive part of the equation.

    The 8611LP's that are running the RED manifold are markedly slower but there aren't a whole bunch of them out there ( couple of hundred ). The BLACK manifold has larger porting and flows much better improving speed.

    The new Black motors with a Power and Ground upgrade move much better than with the stock harness alone.

    If you want to see the difference in smaller to larger cyls just find someone with an XLS or Wideout and push some wet snow together and try to angle a full blade of snow.
