cafoose 3,668 #1 Posted yesterday at 01:32 PM Been having problems with traction on my 953 I got from @Ed Kennellwith the SMS-50. I first put chains on it and that improved it a lot but it was very bumpy. I found four used 14 inch side by side tires on FB for $20 Put the 27-9-14s on it and it pulls like a dozer I still have the 27-11-14s I'm thinking of trying but I need wider wheels. What size wheels for the 27-11-14? 5 2 Share this post Link to post Share on other sites
oliver2-44 11,326 #2 Posted yesterday at 02:26 PM (edited) FWIW if you go wider you will lose some of your traction, or you will need to add more weight. Edited yesterday at 03:13 PM by oliver2-44 3 1 Share this post Link to post Share on other sites

Pullstart 69,237 #5 Posted yesterday at 05:34 PM It looks like the right side tire has more traction? I’d flip flop that to the left, and add left side weight however you can. I stacked two weights on the left and have none on the right of my 753 sickle machine. 2 1 Share this post Link to post Share on other sites

I stacked two weights on the left and have none on the right of my 753 sickle machine. Noticed the sickle side was much heavier when I jacked it up to change the tires I may have to add more weight to the opposite side Maybe I'll put an 8 speed in it so I can go slower and cut more efficiently sometimes even first gear seems too fast for the sickle Does your 753 have high/low range Kevin? 1 Share this post Link to post Share on other sites

If you have an extra GT-14 axle and differential around they could go into the six speed for the limited slip feature. 1 Share this post Link to post Share on other sites

GT-14 all have limited slip? Is there room for the high/low lever in the 953 without modification? What all have the six speed?

Perhaps the reference was to the longer axles in the GT-14 which could be paired with an LSD from elsewhere? 5060 and 5071 Unidrives are "6-speed with limited slip differentials". 5060 with aluminum endplates and 5071 with steel.

My 1970 GT-14 has a limited slip transaxle. I installed a six speed in a 953 many years ago, at the time I didn't know about the GT-14 axle swap. I did have to drill and tap a new hole in the case for the mounting point and elongated a hole in the mounting plate. No Pictures but it was no big deal. This thread will give you all the answers about six and eight speeds. 1 Share this post Link to post Share on other sites
Handy Don 16,057 #14 Posted 1 hour ago The external characteristics for “6-speeds” are: - 1-2-3-R shifter - Hi-lo shifter - No top-side hole for a dipstick - A 1” pipe extension on the oil fill at the lower left rear of the transaxle (allows filling oil to a higher level) - ¾” input drive shaft (that’s also shorter than later 8-speeds’ ⅝” shaft) - A brake drum that brings the brake band to within an inch of the rear axle housing casting - A brake drum that turns clockwise when the tractor is moving forward There was at least one “8-speed” that also had a LSD--I think it was the 5073. This had a topside dipstick port and the brake drum was farther from the rear axle and turned counter-clockwise and had a ⅝” input shaft making it externally indistinguishable from an open-differential 8-speed. As for the rest, the link to the thread in @953 nut’s post (above) has the relevant information. 1 Share this post Link to post Share on other sites
