There never seems to be enough demand from new-to-tractor owners for aftermarket suppliers to be viable over the mid to long term. The experienced don't need them.
New PTO powered implements, connecting to new tractor PTO splines are always difficult. Once implement and tractor PTO parts are somewhat worn in, connection becomes easier.
Lubrication and technique are the keys.
Most here like Eureka Fluid Film as PTO lube. I prefer wax chain lube in an aerosol can.
Grease is too thick.
WD-40 burns off. Shaft goes on "OK" but can be difficult to remove when hot.
Connect all TPH pins. Lift implement until implement PTO shaft and tractor PTO spines are perfectly level, one with the other.
Turn tractor engine off, so tractor PTO splines can be turned by hand.
Turn male splines by hand until they align with female shaft indents. Slide shaft onto tractor splines.
If the PTO shaft and tractor splines are not perfectly level it is almost impossible to slide shaft on to splines.
I am 73 years old. If I can connect PTO without too much difficulty, you should too.
SSQA is money well spent. PTO quick connects are needless complication. (KISS Principle.)
Note: Your tractor and my tractor have the same power.
