Nope, you are not the only one! I can get any of our 3 with ILS to powerhop so bad you can't stay in the seat!! Active seat too! One of them just came out of the shop too with the ILS working perfectly! And I bet I can still get it to powerhop even with the correct tire pressures and weights! But it is a lot better then a regular front axle!! Tracks are just very, very hard to beat out in the field!!

edit: On this Sunday morning sitting here reflecting on what I posted last night I should add that our choice of tire probably has a lot to do with powerhop. We have to use fairly narrow row crop tires and having more then 1 set of tires per tractor is unheard of here. lol
