Lawn Mower: Replacing 54" Hustler mower blades: Torque specs and tool tips?

Fri, 28 Aug 2026 01:27:51 -0700

Hi all, blades on my 54" Hustler zero-turn are pretty chewed up at this point, probably hit a rock or two more than I'd like to admit.

Anyone actually run these instead of OEM? Curious how they hold up.

Also, before I get under there — what's the actual torque spec for the blade bolts on this deck? And I don't own an impact wrench or a dedicated blade-locking tool, so what's the safest way people have blocked the blades to break the old bolts loose without one? Don't want to round anything off or end up fighting it with a pipe wrench and a prayer.

Thanks.

Dewalt Rotary Hammer DCH133B TYPE 1 2016: DCH033 Chuck Won't Hold Bits

Thu, 27 Aug 2026 17:15:02 -0700

The chuck on my Dewalt hammer drill DCH033 won't hold bits. I purchased a chuck repair kit, but that wasn't the problem. There's a gap below the sliding tube that should not be there, and I can't figure out why or how to fix it. The drill is fairly new and has only been used a few times.

FixHub Smart Soldering Iron: FixHub Web Console Connection Error on Ubuntu(Solved: user permission)

Wed, 26 Aug 2026 14:08:37 -0700

I was encountering a "Connection error" when trying to connect my FixHub Smart Soldering Iron to the web console at ifixit.com/fixhub/console. I am running Ubuntu 24.04.2 LTS and using the latest Google Chrome browser.

The error message stated: "Make sure you do not already have another connection open and try again."

I tried the following troubleshooting steps without success:

Fresh boot with no other applications or browser tabs open.
Tried multiple USB ports.

The solution that worked for me was adding my user account to the dialout group. I used the command: sudo usermod -a -G dialout (replacing with my actual username). After running this command and then logging out and back in, I verified I was added to the group using groups and was then able to connect to the web console successfully after a reboot.

This seems to be a common permission issue on Linux systems for accessing serial ports.

Toshweld ARC-200: Toshweld ARC-200 inverter welder: fan works but display and power ligh

Wed, 26 Aug 2026 06:12:29 -0700

I have a Toshweld ARC-200 inverter welding machine.

The problem is intermittent. When I turn the machine ON, the cooling fan runs, but the digital display does not turn on and the green power LED does not light up. There is also no welding output.

The power switch has been checked and it is working correctly. When the power switch is ON, the fan runs. When the power switch is OFF, the fan stops.

Previously, the same problem occurred. The next day I turned the machine ON again and it worked normally: the display came on, the green power light came on, and the welding output worked. Later, the same fault returned and now the fan runs but the display, power light and welding output do not work.

The machine specifications are:
Model: ARC-200
Input: 220/230V, 1 phase, 50/60Hz
Rated output: 200A
No-load voltage (Vo): 62V
Duty cycle: 60%

I want to troubleshoot and repair this machine step by step. Please help me identify which section I should check first. In particular, I would like to know where the auxiliary/control power supply for the digital display, green power LED and welding control circuit comes from after the main power switch.

I have a basic electrical tester and screwdrivers, but I currently do not have a digital multimeter with test leads.

I can provide photos of the machine and PCB if needed.

Toro Walk-Behind Lawn Mower: Motor stalls when it gets higher grass to cut

Fri, 21 Aug 2026 09:01:16 -0700

Motor stalls when cutting load increases and sometimes dies entirely. It can be restarted easily but is basically useless for mowing a lawn with more than an inch to be cut. Acts like it can no longer increase gas to engine when rpm decreases due to cutting load.

Ryobi Cordless String Trimmer P2009 2019: What could make a string trimmer motor suddenly stop working?

Fri, 21 Aug 2026 08:03:29 -0700

Trimmer is 3-4 years old, lightly used. It was working normally for several minutes and suddenly stopped. Had run into some vines, but none were wrapped around the head after stopping. Fully charged battery, not overheating. When trigger was pressed the motor slight "bumped"--did this several times, but then no more reaction from trigger.

Took apart--thoroughly cleaned the contacts on unit and batteries. I see no issues with wiring anywhere. The motor turns freely (with slight bumps every quarter inch, which I assume is normal. Don't know how to test if motor is issue, or trigger component or circuit board.
Replacement motor (could only find one, $108--too much to put into an older Ryobi) and don't know that this is the issue.

What could make a small motor like this suddenly stop working? Is there any way to take it apart and repair something inside the motor?

As the title suggests, I'm wondering if I can fit the Mako driver kit inside of the Pro Tech Toolkit Go's Tool-roll. I opt for this instead of buying the pro tech toolkit because all I want are more bits, and I am not looking forward to buying an additional kit just because of the bit-count.

FixHub Portable Power Station: PowerStation bricked after firmware update

Wed, 19 Aug 2026 20:47:20 -0700

Hi,

I just purchased my FixHub Soldering Toolkit today and decided to upgrade to the latest firmware. It came with 1.0.3 and after upgrading to 1.0.7 it no longer detected the soldering iron. I decided to downgrade back to 1.0.3, but this errored during the 'resetting device' stage after it uploaded the firmware.

The display no longer shows anything at all and the device seems to not power on. I opened it and disconnected the battery for 10 minutes then reconnected it and tried to power it on with no luck.

I can put the device into DFU mode by holding down the silver knob while connecting a USB cable to the back port. It will load up in the web console, but it still shows 1.0.7 on the device and no downgrades succeed nor will the device power on.

Please help!

My saw no longer holds blades tightly. The "key" just keeps turning in the "collar". The threads on either the key or inside the collar must be worn or damaged. Can I remove and replace the "collar" device? Removal instructions would be helpful.
