    My single cylinder bucket seems to have a loose connection between the shaft and the pressure plate , for lack of better words. The part of the cylinder that moves when oil pressure is applied. See video and frozen frames of video in pics. My strain is lifting the weight of the bucket. It made...

    Questions for Kubota BX 2680 owners with FEL

    I have a new BX2680 and just added a FEL LA344. With out the FEL, it drove fine and no noticeable effect of 4wd. With a load of dirt in the 54 bucket, when I turn , it feels like I can feel the gears in the front end not grinding but engaging. With going really slow it seems like I can count...

    I am switching to a BX2680 model from a B3350. ( Unit too big) My B unit has the GCK60-30B catcher. The base blower is the same, just the mount system. Because to the larger B tires, the blower was hung further back. I am planning to copy the Kubota design and have bought some tractor...

    Buying Advice Downsizing from B3350 to BX2680 or BX23S

    I love the B3350 cab model with A/C and heat. I pickup my grass with the rear pto driven bagger. Works great using the 60 deck. But the machine is too heavy (2400lbs) and constantly tears up the lawn. Not full sun so weak grass. DPF issues have been solved for me but I know I will take a hit...

    Add a cab, get a lift platform---re-purpose a ROPS

    Last year, I added a Laurin cab to my L39 that replaced the factory ROPS. With no interest found in the ROPS parts, they hung around. I needed a platform to get to a camera so I tried the plane roof liner( sheet metal and ribs) and found I need side rails for safety and comfort. I cut down...

    I've finished my Laurin cab installation. I added extra lights and replaced the factory lights with LEDs. Looking forward to deep snow. I can't bring myself to cut up the ROPS without a serious try at a new home. I don't have a project requiring the steel either. So, see the pictures and...

    I had planned on telling my experience when I was done. But I've come to this group for several issues and I have another. The heater core threads were BSP (british standard pipe) and I got my parts from McMaster Carr and they fit the engine. Thanks to KWentling and rScotty However, I have...

    Adding a heater to a Kubota. Metric Threads?

    I'm adding a heater core and the recommendation dedicated coolant ports have plugs. They are close to a 3/8" NPT but I only get 2 turns and they stop hard where the plug goes in all the way. I'm looking for the right thread size rather than deform the brass adapter. It's approx 19 threads...

    Adding a new Lauren Cab to Kubota L39tlb. What to do with old ROPS.

    I'm in the process of installing my new Lauren Cab. I see no future in ever returning it to original ROPS. Does anyone need replacement ROPS support members? I'm reusing the tupperware roof but it seems a shame to scrap out the tubular supports and subroof. I suspect they're only good for an...

    Chipper Kubota L39 TLB needing 12v for attachment

    I've just added a BearCat pto chipper and need 12 v for the controller. I've previously tapped the battery for a snow blower but I was wondering if anyone already solved this issue like from tapping the seat or the side console for 12 volts. Key switched would be nice. Most power is key...

    3-Point Hitch PTO Output for wood chipper

    I was wondering about the PTO power out rating on tractors. To use my tractor as an example, it's rated at 39 hp gross and 37.4 hp net with a max pto at 30.5 hp. It makes sense that the sum of the power users can't exceed the source. And I would expect some mechanical losses in the drive...

    Chipper Under powered PTO Chipper

    I was wondering if anyone could comment on having a PTO chipper with a recommended pto hp of 35-60 powered with 30hp. Or under powered from recommended. The unit has an intelligent feed system that supposedly slows/stops the feed to let the cutter catch up. My speculation is that the max...

    Modifications to Front FEL hydraulic snowblower on Kubota L39TLB

    A couple of changes to my Loftness front hydraulic snow blower. I changed the hydraulic motor from an OEM 4.9 cu inch to a 3.6 cu inch. This was because the L39 has a maximum flow of 11 gpm at its front aux. This gives me a maximum rpm of 686 (measured) at engine rpm of 2650. The performance...

    Snow Attachments How to not break the hoses from a L39 TLB to a Front mount Hydraulic snowblower

    I want any mechanical ideas on how not to break the hoses or fittings when I inadvertently raise the FEL and tip all the way down-- Picture A. I'd like to take the slack out of the hoses and mount the cushion valve but too short and I'll break them on some numbingly cold day when I forget I...

    Floor jack not holding under pressure

    My 3 ton floor jack will move its entire range with no load. When I tried to lift my tractor to add chains, it would " slip" and not lift. No oil leakage in its life at least where I stored it. I'm giving it away but thought "working" would be nicer. What is the most common failure for...
