    Default SHORTER LOWER ARMS??

    I've read here that the PAT'S easy change system lengthens the lower arms by about 4", which may cause PTO shaft to be short. I guess it's cheaper to get longer PTO shaft than to replace lower arms with shorter ones. Anyone know what shorter lower arms might cost for replacement??

    $19.95 would certainly be the better option. Thanks.

    I'm pretty sure that 4" figure you read would have been one of the larger PEC sizes. I think the Cat 1 is closer to 2.5", so you might want to recheck your numbers before spending money unnecessarily

    I just looked at mine (Deere 790, Cat 1). It's a good 4".

    I don't doubt you measured 4" someplace Roy. But my Cat 2 PEC measures 4" from the center of the swivel ball pin to the center of the implement lift pin. So if a Cat 2 is extended 4", it stands to reason that a Cat 1 would be less than 4" - by virtue of the smaller Cat 1 hook size and lift pin diameter.

    That said, I've never actually measured a Cat 1 myself - I'm just repeating that 2-3/4" measurement posted by another Cat 1 PEC owner last year. Perhaps there's been a design change at Greenwell since that measurement, and/or since my Cat 2 was purchased.

    I believe they use the same forging for both Cat 1 and Cat 2...just the hole sizes are different (Cat 2 has a bigger hole diameter).

    All I can say is the distance from the ball (on the lower link) hole to the center of the lifting lug on my Cat 1 PEC is 4".

    Think about what you just wrote Roy. The Cat 2 PEC hook has to to be sized to pick up a Cat 2 lift pin 1-1/8" in diameter. It also has to be of sufficient strength to safely pick up a Cat 2 implement. The Cat 1 would be constructed to deal with 7/8" pins and lighter implement weights.

    I measured mine with an implement mounted, a boxblade wearing Cat 2 lift pins. Center of lift pin to center of swivel pin is 4". I'm struggling to see how the smaller Cat 1 PEC - unless redesigned since I bought mine - would measure the same.

    Perhaps George's question would be more accurately answered by simply calling Greenwell's at (888) 243-4204. That way he could get a measurement on the current Cat 1 design.
