    Need help

    It is important you understand the hydraulic flows on your tractor. The main pump feeds the loader valve. The loader valve has 7 ports on it. 6 of these are strictly for loader functions. The 7 port is a power beyond port which is the hydraulic supply to the 3 pt hitch and any rear remotes...

    M5040 vs M6040

    I have a M7040 bought in 2012. The M6040 and M7040 seem to have the same base engine but the turbo may be the difference. NIW has posted previously on the reliability and desirability of the 7040. One feature which has changed is the brakes. The later model M7040 and perhaps 6040 have much...

    Burning Belts

    Has anyone been adding coolant to the AC? The kits with a can can easily result in an overfilled system. If you do not know the history of the machine from day one, consider getting a mobile truck mechanic to come and put his gauges on your tractor's AC system before stating to replace parts. An...

    RC60-72H on b7200hstd

    Could you please post a photo of broken end of the blade bolt. When you have replaced the broken bolt, slowly rotate the blade and make certain the end of the blade stays the same distance from the underside of the mower deck. To break a bolt repeatedly, something is wrong. If the spindle is...

    Stabilizer of Kubota 2660

    A stabilizer with a slender shaft will be strong when in tension, i.e. pulling but very weak in compression, i.e. backing up. The stabilizer to use a technical term is BUCKLING You need to be raising any implement on the 3 point hitch when your stabilizer is of this style. "In engineering...

    End cap

    It will help if you describe which cylinder on your LA302 FEL. What were you doing when it broke. There are things you should never do with a load like pushing with the bucket tilted. If you are using long pallet forks the risks are even greater. Dave

    B2710 hydraulic system not working after changing fluid and filters

    Another trick which has helped some is to use a shop vac on the blow setting and pressurize the transmission thru where you added oil with the engine running. Suction air leaks usually do not involve fluid leaking out which is why they are so hard to find Dave

    K725KH no start

    If you followed Kohler's instructions and their motor does not work, this means in their world you have determined the problem lies with the motor so stop checking anything on the machine. Did you download and read the Kohler WSM that I provided the link for? What happened when you removed the...

    K725KH no start

    I have a Toro with a Kohler Engine. I always find Kohler's web site is very useful when it comes to no start situations. Kohler CV742 service manual Kohler recommends you break the connector which ties the engine to the equipment. In that connector is a white wire which is the 'KILL" wire for...

    This is my 3pt ballast..............

    David I make this comment because I worry too much. If your log pulling is placing loads on your tractor above the level of the draw bar you may run the risk of the tractor flipping over backwards if a log snags on a stump. Would "wheelie bars" be a possible addition? Dave

    This is my 3pt ballast..............

    Nice work! Since you are working with solid material, do you do anything to get welds which involve the complete cross section of the steel pieces? I am not a welder but have been watching this Australian fixing a big bulldozer blade and am amazed at the tricks he uses to do the repairs...
