Hi-Lo Setup on Broadmoor

Recommended Posts

Brent_Baumer
The 707 Broadmoor I have for sale (parts only) there is a Hi-Lo shift lever. I was told by the previous Owner the Hi-Lo did not work. Upon inspection, I cannot tell how it was supposed to work. It looks like something is missing. I am not at all familar with this setup to know and have gotten a couple of inquiries about selling it off the tractor. Question - can anyone tell what I have (or don't have) here? http://www.simpletractors.com/club2/uploaded/Brent_Baumer/HiLo3.jpg http://www.simpletractors.com/club2/uploaded/Brent_Baumer/HiLo4.jpg See pics in my photogallery. Cannot make them attach here for some reason. Thanks, Brent

Brent, Be aware that the high-low for the Broadmoor won't fit Landlords and Sovereigns, at least without some significant engineering/machining. You have some parts missing. I've included a picture of the Landlord setup, just to point out some missing pieces, and how it works... You're missing at least the pivots and bushings on each side of the linkage. In this picture, above, those pivots are the little things on the very bottom of the "hoop-shaped" shift linkage, down where two layers of steel are visible. Just above them is a shoulder bolt that this "hoop" swivels on. There's a pivot and a shoulder bolt on each side of the hoop. The pivots are aluminum (or something similar) with rubber inserts, and a slot in them that the tall flange of the pulley rides in. The pivots have shoulders on them, and just stick into a hole that goes through both the layers of steel down at the bottom of the hoop. When you move the shifter knob to the left, the linkage hoop swivels on the shoulder bolts, pushing the bottom of the linkage hoop and the pivots to the right. The slot in the pivots grasp the tall flange on the pulley and push the pulley out to the right. The outside half of the pulley slides (the inside half is locked on the tranny input shaft with set screws) out, and the main drive gear inside engages a set of 6 (?) small spur gears like those in a differential. These provide a 1/3 gear reduction -- i.e. low speed range. When you move the shifter knob to the right, the hoop swivels and the slot in the pivots pushes the outer half of the pulley back in, disengaging the main drive gear from the spur gears, and engaging a ring gear instead, giving a 1:1 gear ratio -- i.e. high speed range. It looks like you may also be missing something that functions as a stop to stop the outside of the pulley from turning while you are in the low speed range. On the Landlords, this is the piece just above the center of the pulley, held on by two long bolts that also hold the bracket that the hoop swivels on. When you push the pulley out, that stop will go down between the small, square-shaped "nuts" that are visible around the pulley, preventing the outside of the pulley from turning.... Hope this explanation helped, though I don't have any pictures (at least loaded to the site) that show all the parts of the Broadmoor setup... The foot-draggin' Clubhouse Custodian...

I think Sam is right.I have 2 of them for the Broadmoors and both of mine have the plastic style pivots.In fact I just replace them on my 728.I have the manual for the Broadmoor HI/LO kit.It shows the part # for the pivots to be:156261.I belive they are about $11 each. mowerman1193

Yes, I now remember Sam saying earlier that the pivots were plastic on the Broadmoor... the shaft sizes are different, and there was one other major difference, but I can't remember what it was... What functions as the "stop" on the Broadmoor design? Or, is there one? The foot-draggin' Clubhouse Custodian...

Thanks for the info fellas. Hey mowerman, would it be possible for you to scan a pic or drawing from your manual and email or post it? Thanks again, Brent Oh 1 more thing - are there any tricks I need to know if I remove the hi-lo from the tranny? Any small parts that may go flying or anything that is easy to damage if you have messed with one of these before? Brent
