How To Measure Pto Shaft Length

I am purchasing a used PTO powered spreader and was wondering if in that location is a standard mode to figure the correct length of the PTO shaft and what the minimum overlap the shafts need for prophylactic operation.

Minimum overlap of the two shafts should be effectually 6" - more than is meliorate.

Maximum length should requite you about four" from your tractor'southward PTO point when fully compacted (slid together). This allows for easier attachment and allows the 3PH to be raised and lowered without binding.

However, there are heavy duty PTO shafts that have a 4" long bushing on the stop that is the only date. In gild to shorten it you have to cut off the bushing and weld it dorsum on the shortened shaft. (from Tractor Supply)

Oh, and I store my PTO shafts apart (in ii pieces) and lightly greased. Some shafts only go together i way so a little grinder mark is made on the ends of the shafts to show how to line it up for re-assembly.

one matter in video vs PDF manual., is the video goes into some detail well-nigh cutting the PTO shields a lilliputian bit more than than what you cutting the shafts. so when yous become to slid both ends of the PTO shaft back together. you can actually practise it. vs hassling around trying to blindly get ends of the pto shafts to slide back together.

fully raised or fully lowered will most likely crusade PTO shaft to "extend" vs contract the shortest corporeality. when the PTO shaft is level maybe a lilliputian higher or lower than being level, is well-nigh likely when PTO shaft will exist at the shortest collapsed length.

they say 6" min overlap. and if shaft allows longer the meliorate. i can get myself into some pretty hairy situations, going through gulleys and ruts, going over a log or rock. that tin can crusade 3pt hitch equipment to really bend and cause PTO shaft to expand (lengthen). more and so on pull behind equipment like a trailer or something, that does not directly attach to the 3pt hitch. with that noted, if you lot take a choice betwixt a shaft that just barely gives 6" overlap vs a longer PTO shaft that volition give more than overlap, i might pay a few actress bucks, for the longer shaft and cut it downwards as needed. for those things that are like trailers (manure spreaders) and like. so when i get over that pile of grime, or tire goes down into a rut. the shaft does not pull autonomously.

things that physically adhere to 3pt hitch (both lower arms and top link) 6" overlap nigh likely exist ok within reason, due to implement can only get so far due to 3pt hitch ability to just become and then far upward or and so far downwardly.
