I have a 2018 Massimo Buck 400 with 278 miles. Having issues with my brakes. Took the buggy hunting and when I let my foot off the gas pedal it pulls without pressing on the brake. I looked and the pads on all 4 wheels are all toast. The E-Brake hasn’t been on since I have had it. I am guessing it may be a master cylinder issue because all 4 pads are gone. They all seem to have worn evenly that’s why I think the master cylinder. Just got the machine used from a older couple and they said it sat for some time in there pole barn. Possibly the brake lines? Calipers? I took one brake apart and when I depressed the caliper it didn’t stay. Any help is muck appreciated.

2020 Massimo Buck 400 - Won't start. Can hear the starter spinning, but motor never turns. Relay? Starter? Worked fine one day and not the next. Thanks for any help you can provide.

Please help I have a Massimo 400 buck that has an oil leak. The oil is leaking on the front side of the motor. It leaks out of a u-shaped steel pipe that has two banjo style fittings on it. I have tried using RTV and different banjo washers and have had no luck. It drips about one drip per second while it's running. I can't find parts for it at this time.

Does anybody have any experience with a Buck 400 on the road? I have license plates on mine and was curious to know if anyone else does too. Also if anyone knows if this thing can sustain 40mph for and extended amount of time.

Just wondering if anyone has or had this issue with high idle. When I start my UTV, it idles at 3 RPMs making it hard to shift without it grinding gears. This just happened and I haven't had very many miles on it at all. I called customer service and they told me it could be the idle control sensor. I bought a new one and replaced it but it didn't solve my problem. Is there any other adjustments or something else I need to replace? I don't see any adjustments to lower my idle on throttle body unless I am missing something?

I have changed spark plug, starter solenoid relay and battery. It has power but will not crank. Just a click and nothing else. Lights and dash come on. What is it I am missing? Need help. Thanks.

Hi all.....I have a strange happening with my Massimo Buck 400. I tried to start it half way through the winter and it wouldn't fire as the battery was low (I should have disconnected the ground before winter), nonetheless it cranked a few times then when I turned the key to shut it off to be dealt with in the spring it kept trying to start itself, no key turned at this point. Spring comes and I charge the battery up, but it continues to do the same thing with the machine trying to start itself when no key was inserted. I suspect it might have to do with the solenoid, or a faulty key switch. After repeated tries it finally started, and is now functioning properly. Does anyone have any idea as to why this might have happened.

Hey guys.... Have a buck 400 that the shifter lever has all but frozen up on. Is it a linkage or cable design? It got more stiff last year during deer season and after sitting for months in my barn will not really move in either direction. I do not want to force it to free it up and risk breaking something. I guess I have to pull the front clip off to see what the issue is but thought I might ask beforehand what type of operating system was ased on yhis model. Linkage or cable....Thanks.... Lee

Does anyone know of a generic cable that will fit? Massimo do not stock parts for this model, they sold me it last year new , now inform me they carry no parts! Crazy bad customer service. Anyhow I got Boss order in but it's back ordered. Buck is parked up untill I can either find a cable that will fit from another make, or have one made or wait until part is available a Boss. Anyone?

I purchased this Buck 400 last year and having a few issues. Maybe some members have had these and fixed them. Here are my current issues with the B400. 1. Starting has become a challenge. Not the actual starting of the engine but to keep it running. When I turn the key, it starts up but as soon as I let go of the key and it turns back, the 400 dies. I have learned if I hold the key for a few seconds it will remain running. Not a clue as to what would cause this or how to fix it? 2. This thing is very hard to get in gear now. It grinds a lot before it goes in gear. Maybe the clutch needs adjusting? 3. I jerks a lot on take off. This could also be the clutch? Any help would be appreciated.

Buck 400 at first would not turn off. Sounded like starter was still running. Finally got it to shut off. Turned back on and ran about 50 yards and it died. Now when I turn the key, absolutely nothing happens. Battery hot.

I've looked long and hard and can't find an oil filter. Wondering if there is one. Any help would be much appreciated. Also, live in Canada - we have no Massimo service centers or dealers, only HiSun. Are HiSun and Massimo related?

Hello, I'm back from Kawasaki 2004 3110 Mule land and now am struggling thru the Massimo Buck 400 swamp. I bought a 2019 Buck 400 with 200 hours on it and am going thru the owner's manual. I have noticed a couple of things needing addressed after driving it home. I t is rough starting off, like maybe the drive clutches and or belt are not exactly right. also the parking brake is a question mark. The manual shows (seems to me) that pulling the handle down should disengage the parking brake, not this one, pulling up disengages the parking brake, also the handle is really hard to move while holding the super strong button. The handle will only go down a smidgining past half way. Do I need to work on this? This old man will ask for help in a NY minute! please stand at ease, I' will be in the area. Actually that was 200 MILES and only 22 Hours.

I have a new Buck 400 with about 60 miles on it. It runs great but can only get it up to 23mph. Is this normal? If not what speed are others gettting.

I have a Massimo 400 Buck that won't start. When I turn the key, I get nothing, no lights, the meter doesn't light up, etc... I replaced the ECU and everything lit up, it cranked perfect, ran for a couple of minutes and shut down again. I have tried calling Massimo, they are pathetic, have been waiting a week for a return call. Any idea where to look?

My Massimo 400 Buck jerks and surges in reverse when cold. Help! Only 60 miles on it.

I just bought a new buck 400x golf and just signed up to this forum. Lots of good info and glad to be here. I took off seat to see the engine and noticed a black circular pipe just sitting exposed leading to the engine bay. As well as a rectangular pipe coming off crank case and possibly even an electrical harness or two with nothing obvious to plug them into? Does anyone have the buck 400x golf and take a picture or look in their engine bay and let me know if this is normal or if there is something missing on my cart. I reached out to massimo and let them know that it was unusable if this is actually an important missing part it probably shouldn't be driven, they said I should hear back in 3-5 days but that they are very busy. I figure if one of you has one you can take a look for me and I don't have to wait around on massimo to answer me on what a normal engine bay looks like. Thanks for your help,

My new Buck 400 EFI has to rev over 4,000 RPM before it moves and seems to be slipping when placed under a load. Is this normal?
