just got my new to me 8970  ps.trans 3500 hrs. great tractor lotttttsss of power any advice to keep it that way?

i have a few questions:

want to put on a pre cleaner would like to use a stainless one ive seen on others who is mfg? where to get? dealer wanted to sell me a turbo tt,he didnt know mfg of what i wanted !

seat seems worn out jd replacement? or is there a newer 'active' version? it is air suspension

1&2 hyd levers seem alot stiffer and harder to feather than my 55 sieries and detents half work. is that because of cables instead of linkage like 2 wheelers?are new silky smooth, do they stay that way?

when shifting 6&8 gear jerk tractor real bad (moves mirrors)much harder than the 15 speed ps is that normal? nature of the beast?

what is the rpm range to use field cruise whats to low rpm?

thanks for your thoughts  safe harvest to all
