Kubota GR2100 Owners

[davepage]

Yo Acolar-

I have a 2005 GR2100 with catastrophic HST failure as well. I'm a commercial turf maintenance contractor, and i'm trying like **** to get it fixed before April when mowing season fires up again. I just recently learned via the internet that Kubota has extended the warrant on this HST to 4 years, not clear yet if that applies to commercial users. My failure was discovered at 2yr. 15 days, 365 hrs. I have the work shop manual and parts list, and since i believed it to be out of warranty, tried to fix it myself. Beware, the trans has been redesigned and I don't think the old guts are compatible with the new case. I've cracked 2 cases trying to put this back together, would have been nice if someone in the loop had said something when they saw these part orders coming through[is that for a GR series HST?????? Stop the presses]. It ain't over yet but it's been a battle to this point to try and get any support.

Simple adjustment guys... remove key, chock wheels, remove back cover and release park brake assembly. ( have a Beer) loosen locknut on brake spring adjusting nut, have your bud lift up the brake petal by hand or pull up and block ( if no bud available) a woman can be substituted for this procedure but they will become bored and impatient quickly... promise to take them shopping after adjustment. ( have another Beer) Next measure spring tension... Should be 73 to 74mm length under tension, if not proceed with tighting the adjusting nut until the spring contacts the base of the brake arm. ( have another Beer) now mark a flat on the adjusting nut with her lip stick ( this gets a reaction out of her and takes her mind off the operation) back the nut off three complete turns and tweek the adjusting nut to get the 73 -74 mm and now tighten the double nut back. ( have another Beer) Don't put the cover on yet ( we may have to go back) now gently remove her hand from the brake and tell her how wonderful it is to be spending time with your two favorite things in life ( have some paper towels available things can get wet) Check the free travel of the brake petal by hand for 15 to 25 mm engagement. If not found, repeat step 2 but use a BUD this time or a block and recheck compressed spring length again (and I don't mean (B)ig (U)gly (D)ish you watch Satellite TV on or feed your dog with) check free petal engagement again and this time engage the park pawl with your left foot while depressing the brake petal with your right foot ( you should be sitting in the seat while you have another Beer ) Now gently climb off the seat and get down low enough to see that the locking dog is fully engaged in the detent. ( have another Beer) now if the locking pawl is not fully seated into the petal cross shaft linkage start throwing everything you can grab in site...because you will need to pull the seat, fender and wiring and look for bent linkage and measure against factory drawings to see what needs replaced. ( have another Beer ) If you used a Woman in step two you must now keep your promise to go shopping ( have anothver Bere ) she gets to drive!

This brings up a good question for Ob1,our gr2100 guru. I'm experiencing the same problem that larrystrollo is haveing with the parking brake. I work on very steep terrain and once, just from my weight mounting the mower the brake disengaged on it's own. Now I carry a 4x4 chock for the wheels when I park on the slope. Often it takes several stabs at the foot lever to engage the parking brake. It also seems that the natural vibration from diesel engine over rides the locking mechanism. Is there an adjustment that can make the parking brake more positive?

Have the same problem with my GR2100 (April 2005). Have you looked at the ratchet assembly for the parking break. The teeth on that are so small you could use them in a wrist watch. My thoughts are that if the teeth wear just a little over time it will not hold.
